41xx steel is a family of SAE steel grades, as specified by the Society of Automotive Engineers (SAE). Alloying elements include chromium and molybdenum, and as a result these materials are often informally referred to as chromoly steel (common variant stylings include chrome-moly, cro-moly, CrMo, CRMO, CR-MOLY, and similar).

4140 [definition needed] 6150, a chromium-vanadium alloy. Similar to 4140, 6150 is a tough steel with high impact resistance. It can be hardened to the mid-50s on the HRC scale. [citation needed] While a common material for swords or hatchets, it is less than ideal for most knives because of its limited attainable hardness.
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 involved in efforts to standardize such a numbering system for steels.
