Physical Properties of B16 Alloy Steel
- B16 alloy is typically hardened by oil quenching and tempering after the part has reached room temperature
- In diameters over 7” water quenching may be used to meet Charpy impact properties
Mechanical Properties of B16 Alloy Steel
- Generally, B16 alloy steel bar is supplied in the quenched and tempered condition where the hardness is normally Rc 35-43. In the annealed condition, hardness is typically 187 BHN.
- Generally supplied in the quenched and tempered condition, machinability is similar to standard AISI alloys such as 4340.
