1. Cracks appear on the surface of 15CrMo steel after carburizing
Reason:
a.The concentration of surface penetration layer for 15CrMo steel is too high.
b.15CrM
The alloy layer of the NM500 steel has high wear resistance, and the service life of the parts after surfacing is relatively long, which will increase by about
·Cutting. Use plasma cutting, carbon arc cutting and grinding wheel saw to cut large-area composite NM500 wear-resistant steel plates into required shape
Impact resistance. The impact resistance of the NM500 wear-resistant plate is very good. In the process of conveying materials, even if there is a very high dro
Quenching can improve the plasticity and toughness of 15CrMo steel and reduce its brittleness, but it often inevitably reduces the strength and hardness of 15Cr
15CrMo steel belongs to pearlitic heat-resistant steel. It is mainly composed of chromium and molybdenum alloying elements. The alloying element chromium can fo
Carburizing is a heat treatment process in which steel is placed in a medium with sufficient carbon potential and heated to an austenite state and kept warm to
