The “corten” form of this material, which is designed to resist weathering, (10[1])is an example of its HSLA type. The properties of this material as it is cooled are displayed on TTT and CCT diagrams, such as how it transitions from an FCC to BCC structure during the austenite-to-martensite (10[1])phase change. Reinforced concrete gets its tensile strength (10[1])from this non-elemental (10[1])material’s “rebar”. Air is blown over a certain metal’s “pig” form in order to produce this material in the Bessemer process. (10[1])Either performing galvanization or adding 11% chromium to this alloy is used to avert corrosion. For 10 points, name this strong alloy of iron and carbon, which comes in a “stainless” variety. ■END■
