Product Description

37CrNi3 With high toughness, high hardenability, oil cooling can be completely Φ 150 mm parts hardening.At 450° the creep resistance is stable.Low temperature impact toughness is good.In the range of 450 ~ 550℃, there is a second type of temper brittleness, which tends to form white spots.Because the hardenability is very good, must use normalizing and high temperature tempering to reduce the hardness, improve the machinability.It is generally used in the quenched condition
