Description
8620 is a harden chromium, molybdenum, nickel low alloy steel often used for carburizing to develop a case-hardened part. This case-hardening will result in good wear characteristics.
Applications
Gears, shafts and other applications where a hard carborized case and a tough core are desired.
Physical properties (average values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210 Density [g/cm3]: 7.86
Soft Annealing
Heat to 650-700℃, cool slowly. This will produce a maximum Brinell hardness of 212.
