Grade 20Cr Steel Composition, Properties, Material EquivalentCompared with 15Cr steel, 20Cr has higher strength and hardenability. The critical hardenable diameter in oil is 4-22mm, and the critical hardenable diameter in water is 11-40mm, but the toughness is poor. The machinability is good under high temperature normalizing or quenching and tempering conditions, but it is poor after annealing.
The standard will replace GB/T 3077-1988 from the date of the implementation of this standard.
