Processing characteristics of slope protection mould
It has low hot forging deformation resistance, good plasticity, wide forging temperature range, low tendency of cold cracking and precipitation of network carbide.
2. annealing process
Spheroidizing annealing has wide temperature range, low annealing hardness, small fluctuation range and high spheroidizing rate.
The cutting parameters are large, the tool loss is low, and the machined surface roughness is low.
4. sensitivity of oxidation and decarburization
When heated at high temperature, the oxidation resistance is good, the decarbonization rate is slow, and it is insensitive to the heating medium, so the tendency of pitting is small.
After quenching, it has uniform and high surface hardness.
After quenching, a deeper hardened layer can be obtained and quenched with a mild quenching medium.
7. The tendency of quenching deformation and cracking is small in volume change, slight in shape warping and distortion, and low in abnormal deformation. The sensitivity of conventional quenching is low, and it is not sensitive to quenching temperature and workpiece shape.
The relative loss of grinding wheel is small, the limit grinding amount without burn is large, and it is insensitive to the quality of grinding wheel and cooling condition, and is not easy to occur grinding damage and grinding cracks.
