SCr420 Steel AISI 5120 20Cr4 G51200 1.7027

The SCr420 alloy steel will get MAX 250 HB Brinell hardness. Hardening of JIS Alloy structural steel SCr420; First quenching heated slowly to 880°C, Then after adequate soaking at this temperature quench in oil or water. Temper as soon as tools reach room temperature. Second quenching heat to 780 820°C then quenching in oil or water.SCr420H steel Steel GradesTool & Die Steels Inc.

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.
