Hardness as surface hardened about 54HRC Physical properties (average values) at ambient temperature Modulus of elasticity [103*N/mm2] : 210 Density [g/cm3] : 7.80 Soft Annealing Heat lo 680-720C, cool slowly in the furnace. This will produce a maximum Brinell hardness of 241. Normalizing Temperature:840-880°C Hardening Harden from a temperature of 820-680°C followed by oil water quenching Tempering Tempering
