Heat treatment Related
Slowly heated to 850 ℃ and allow enough times, let the steel to be thoroughly heated, Then cool slowly in the furnace. The 40CR alloy steel will get MAX 250 HB (Brinell hardness).
Heated slowly to 880-920°C, Then after adequate soaking at this
temperature quench in oil. Temper as soon as tools reach room
temperature.
