Feb 01, 2013· For example, intake valves operate at lower temperatures than exhaust valves and, therefore, are typically made of chrome, nickel, or tungsten steel. However, since exhaust valves must endure much higher temperatures they are usually made of more heat resistant metals such as inconel, silicon‑chromium or cobaltchromium alloys.

The SAE steel grades system is a standard alloy numbering system for steel grades maintained by SAE International.. In the 1930's and 1940's, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels. These efforts were similar and overlapped significantly. For several decades the systems were united into a joint system ...

The first experimental site designed for nitriding of ferroalloys by SHS with productivity of 100 ton of the alloy per year was built in 1979 in Tomsk. Nitrided ferroalloys of vanadium, silicon, and chromium are widely used in metallurgy. Nitrided ferrochrome and chromium are added to .
Production Process. Ferrochrome (FeCr) is a corrosionresistant alloy of chrome and iron containing between 50% and 70% chrome. Ferrochrome production is essentially a carbothermic reduction operation taking place at high temperatures. Cr Ore, an oxide of chromium and iron, is reduced by coal and coke to form the ironchromium alloy.
