Heat Treatment
Annealing:
440B stainless steel is annealed at 843-871°C (1550-1600°F) and then cooled very slowly in a furnace. Hardening:
440B stainless steel is heated at 760°C (1400°F), soaked at 1010°C (1850°F) and finally cooled in oil or air. Tempering:
440B stainless steel is tempered at 148°C (300°F) to obtain maximum properties and the maximum hardness that can be obtained is RC58.
