护坡模具制作工艺特性
Manufacturing process characteristics of slope protection mould
1．可锻性
1. Malleability
具有较低的热锻变形抗力，塑性好，锻型槽模具 井盖钢模具 保定雅思 一次性止血带 保定养老院  保定水处理设备 一次性止血带  造温度范围宽，锻裂冷裂及析出网状碳化物倾向低。
It has low hot forging deformation resistance, good plasticity, wide forging temperature range, low tendency of forging crack, cold crack and precipitation of network carbide.
2．退火工艺性
2. Annealing process
球化退火温度范围宽，退火硬度低且波动范围小，球化率高。
The spheroidizing annealing temperature range is wide, the annealing hardness is low and the fluctuation range is small, and the spheroidizing rate is high.
3．切削加工性
3. Machinability
切削用量大，刀具损耗低，加工表面粗糙度低。
Large cutting parameters, low tool loss and low machining surface roughness
