Iron+&+Steel+Chat

Alejandra Pelay: Helloo!!

Alejandra Tarazona: Hi!

chiquinisabel: Hi! as they are ..? Alejandra Tarazona: how are you?

chiquinisabel: fine fine

Alejandra Pelay: Veryy well!!

Alejandra Tarazona: Today I have another issue, known as iron and steel?

chiquinisabel: perfect, hopefully we can clarify our doubts about it: what if we start first with the steel? they know about it?

Alejandra Pelay: Well, iron is one of the best materials for construction

Alejandra Pelay: sorryy

Alejandra Pelay: Steel

Alejandra Tarazona: is an alloy of iron with minor amounts of carbon which has high hardness and elasticity, steel retains the characteristics of iron metal in the pure state, but the addition of carbon and other elements of both metallic and nonmetallic improved physicochemical properties. currently used in buildings, and focusing our work area.

chiquinisabel: if, besides the steel is the name commonly given to an engineering metal alloy of iron with a carbon amount variable between 0.1 and 2.1% by weight of its composition, although these values ​​are normally between 0.2% and 0.3%. If the alloy has a carbon concentration greater than 2.0% are produced foundries, as opposed to steel, are brittle and cannot be forjarlas but must be molded.

Alejandra Tarazona: accurate, also considered a "major innovation in architecture" chiquinisabel: but that makes it so innovative? so what are the particular characteristics that have?

Alejandra Pelay: The steel is more uniformly strong, elastic, and workable, and its high resistance in all stresses (tension, compression and bending) can be closely calculated.

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">chiquinisabel: we also can specify a nice little features like these to be in high mechanical strength: <span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">The steels are materials with high mechanical strength when subjected to tensile and compression and is supported by the chemical contribution having steels. By means of laboratory tests determining the tensile and compression evaluating its elastic limit and the breaking strain. <span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">For Elasticity: The elasticity of steel is very high, in a tensile test of steel to stretch before reaching its elastic limit returns to its original condition. <span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">In Weldability: A material that can be attached by welding and thanks to this you can compose a series of structures with straight pieces. <span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">And in Ductility: The steels have a high capacity to work them, bending and twisting. <span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Forgeability: It means that when heated

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Alejandra Pelay: Depending on the temperature, the steel can contract, expand or merge. <span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Is a very tough, especially in some of the alloys used to make tool. <span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Relatively ductile. It is obtained with thin threads called wires. <span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">It is malleable. Thin films can be obtainedtin, usuallycallscoatedelectrolytically, by tin. <span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">It allows good machining on machine tools before receiving a heat treatment. <span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Some forms of steel compositions and hold more memory, and to deform beyond its elastic limit. Steel has many features.

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Alejandra Tarazona: Can be welded easily. which gives it the ability to adapt to any type of structure, andits greatdensityandresistance. good but we must also consider the iron. iron are saying? What is your opinion about iron?

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">chiquinisabel: good and going to the iron we can say that iron is a malleable metal, silver-gray and has magnetic properties, is ferromagnetic at room temperature and atmospheric pressure. It is extremely hard and heavy. <span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">It is found in nature as part of numerous minerals, including many oxides, and rarely is free. To obtain iron in the elemental state, the oxides are reduced with carbon and is then subjected to a refining process to remove impurities. <span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Alejandra Pelay: It is also widely used as construction material. Bears some resemblance to the steel.

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">chiquinisabel: given all of these features is that it has grabbed so important after the twentieth century

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Alejandra Tarazona: interesting, Alejandra P, and Isabel, well I can say is that iron carbide is the most used, cast iron, was used in bridge construction 1779. Their ability to withstand loads and ability to acquire an infinite variety of forms in addition to fire resistance and corrosion quickly encouraged architectural adaptations, first as columns and arches and later in skeletal structures.

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">chiquinisabel: Alejandra T exactly very good your bounding

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Alejandra Tarazona: thanks...

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">chiquinisabel: good and if we compare the iron and steel with other class materials such as brick or stone .. they feel about this comparison?

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">chiquinisabel: ie what are the advantages of iron and steel on stone and brick?

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Alejandra Pelay: These new materials are more resistant than many previously used in construction, are safer, more durable and give complete security to the construction.

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Alejandra Pelay: However, these old materials such as brick or stone are still used in construction but the main ones are the iron and steel

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">chiquinisabel: the difference is that iron and steel provide strength, durability (currently), ability to be united com efficiency, supporting layers of high and complex structures

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Alejandra Pelay: Exactly

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Alejandra Tarazona: well, when compared with that material, I must say it supports the idea of ​​using the iron and steel, as those materials currently that adapt to the demands of modern architecture. Is best for theirCharacteristicsand Benefits, Beforeexplain to meas, and mentions Isabel. And stone and brick with more for simple things or decorative.

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Alejandra Pelay: Yes, I agree with you

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Alejandra Pelay: But steel has certain disadvantages in the building, which they believe would be the disadvantages?

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">chiquinisabel: the disadvantages can be <span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Oxidation: The steels have a high ability to oxidize when exposed to air and water simultaneously and can cause corrosion of the material if it is salt water. <span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Heat transfer and electricity: Steel is a high power transmitter and in turn becomes very weak at high temperatures, so it is preferable to use nickel steel or aluminum or try to protect them and avoid making vented fuel or plastics factories with this type of material. <span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">These two disadvantages are manageable considering the use of materials and maintenance to be given to them.

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Alejandra Tarazona: Well, I would call a disadvantage the fact good as Isabel says, is very prone to oxidation alsobea greattoolconstruction, but cannot be used everywhere and for all sorts of things, eg you cannot use as door or window frames, not as floor, is not well seen in the aesthetics of modernarchitecture.

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Alejandra Pelay: Exactly, and in construction with these materials is widely used solders! What is its importance? Its characteristics.

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Chiquinisabel: well, I can say thatweldingis simply theunionsof two metals, melt both at the sametime,joinand let cool , then havea fixed connection.

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Alejandra Tarazona:isabel exact, there are also various types ofwelding,TIGweldingwhichhighlightortungsteninertgasarc welding , laserwelding , ultrasonicweldingand many more,but alldepend on thematerial beingwelded.

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Alejandra Pelay: interesting, butis specialin construction?

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Alejandra Tarazona: is of great importance, since from thatfirst used inthe 20th century, materials such as boltsor rivetshave declinedsince thesolderprovides betterbenefits,I can alsosayit's saferthan justa weldrivet,not the worstIdespiseorthe rivetor boltsas it isstill used , but simpleworks.

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Chiquinisabel: Exactly aljandraT.I must add that welding has become an essential element for building the most sophisticated machines that man has done in its history. This progress has been possible only through understanding and creative application of the physical processes that exist during welding. So it is that today, unlike fifty years ago.

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Alejandra Tarazona: good as we've talked aboutthe steel andirons, whichare heavy metals,do you think thealuminumor alloysarealsoheavy metals?

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Chiquinisabel:Otherwise, the aluminum is not a heavy metal; the opposite is primarily considered a lightweight metal, as well as having many uses in the construction field.

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Alejandra Pelay: exact, it is most become so importantthat it isused alsoto improve otherbuilding elements, such as coatingfor steelto prevent corrosion. But keepin mind thatmosthave beendevelopedfor areasthat areoutdoors.

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Alejandra Tarazona: is true and I thinkingthey are better fortheenvironmentbyits resistanceto oxidation anddeteriorationof the climateall.

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Chiquinisabel: Well, againit was funtalkingwith you.ButI have to go.

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Alejandra Tarazona: Indeed,it was fun and pleasure, see you later, take care, bye

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Alejandra Pelay: See you soon, it was a pleasure talkingwith you again. Bye bye.

<span style="color: #2d6565; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 120%;">Chiquinisabel: also, see you soon,bye.
