Up to 2 percent chromium is added to low-alloy steel to improve hardenability, wear resistance, and high-temperature strength. |
Improved hardenability is achieved by adding such elements as manganese, molybdenum, chromium, nickel, and boron. |
While nickel and copper do not affect hardenability nearly as much, they segregate to graphite nodule sites and do not form detrimental carbides. |
First, in a case-hardened steel, the hardenability of both case and core must be considered. |
Because of the relatively high hardenability of A. R. Steel preheating and maintaining this interpass temperature is required on all thicknesses. |
The ability of steel to form martensite on quenching is referred to as the hardenability. |
