3. Hardness
Q+T pre-harden steel, 28-34 HRC
4. Charateristics
P20+Ni steel has good mechanical property and quenching, make surface have equal hardness after deal with it. Nice polishing and low roughness. Normally make the heat-treatment to harden condition before used, it can be used directly after the mould machined.
