SAE steel grades
The SAE steel grades system is a standard alloy numbering system (SAE J1086 - Numbering Metals and Alloys) for steel grades maintained by SAE International.
In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both in ...

high-speed steel
High-speed steel (HSS or HS) is a subset of tool steels, commonly used as cutting tool material.
It is often used in power-saw blades and drill bits. It is superior to the older high-carbon steel tools used extensively through the 1940s in tha ...

[Efunda (Retrieved September 30, 2012):] Chromium and vanadium both make the steel more suitable for
hardening. Chromium also helps resist abrasion, oxidation, and corrosion.
Chromium and carbon can both improve elasticity.
