- Q:Heat treatment of mild steel? Process description macro-micro
- Mild steel is a solution of carbon within iron, etc. When the steel is very hot the carbon is well distributed. As the steel is cooled iron crystals form excluding the carbon that will then collect at the boundaries (grain boundaries) between iron crystals. If cooling is rapid at any point in the cool down crystal growth will cease (affecting final grain size and the mix of carbon and iron at the grain boundaries). The ductility or hardness of the resulting steel will be determined by the grain sizes and makeup of the carbon/iron mix between grains. Ductile iron permits 'slabs' of iron to slip past each other within iron crystals and location of carbon atoms may help prevent slip resulting in hardness. Therefore, heat treatment usually consists of 'soaking' the steel at a temperature high enough to dissolve all the carbon uniformly then cooling it down slowly or rapidly to obtain optimum grain size and interstitial carbon between grains to obtain desired properties.

- Q:How does Steel help us in society?
- steel comes from iron. Iron is a natural resource and is abundent in nature. so being able to turn it into steel means it can be used for alllll sorts of things! from buildings, cars, piping and tubes, to washing machines, appliances and many other things. its used in our everyday life and is a great, strong material.
- Q:Can carbon steel be solution annealed?
- No. Carbon steel has two different crystal structures, FCC and BCC , depending on the temperature. when you heat steel up and then quench it, it locks the crystal structure into the BCC form. this makes it hard. whereas precipitation hardened austentic stainlesses remain BCC regardless of the temp, so the hardness change is not a function of thermally induced strain. you can anneal carbon steel but the thermal profile is closer to the precipitation profile of PH stainlesses than it is to the Solution annealing profile.

- Q:can my 3 nylon guitar strings be replaced with steel ones?
- Depends okorder.com Classical guitars aren't able to handle the tension of steel strings for the most part. Be careful with deciding which type and gauge string to put on certain guitars.
- Q:When did Chevrolet switch from wood spoke wheels to steel disk wheels?
- Wooden Spoke Wheels
- Q:Site that tells the history of Stainless Steel dining Utensils?
- The development of 18/10 stainless steel was the brainchild of Harry Brearley who, in 1913, was working on a project to prevent rifle barrels from corroding so much during use. His analysis of the rifle barrels involved having to dissolve them in acid but, by chance, he noticed that steel which had a high chromium content did not dissolve in the acid. He experimented with varying proportions of chromium and finally produced a stainless steel with 12.8% chromium. He moved to Thos Firth Sons in 1914 and commercial production of stainless steel cutlery began. Refinements were necessary because early versions of stainless steel knives were harder to produce and polish, and they would not cut as well as the existing knives.
- Q:How is steel galvanized and why?
- Steel can be galvinised by electroplating process. Galvinising means providing a zinc coating on steel surface. It protects the material from rusting and loosing the shinining.
- Q:why does steel rust?????????????
- Steel is made by refining iron. Iron is mined as a red powdery ore. Unfortunately, when moisture and oxygen are present, the steel attempts to revert to its original state.
