Cr1 2属于高碳高铬莱氏体钢 ,也是应用广泛的冷作模具钢。该钢具有较好的淬透性、耐磨性、热加工性。碳化物在钢中分布较好 ,可用于制造形状复杂、工作条件繁重下的各种冷作模具。如冷冲模冲头、螺纹滚模、拉丝模、料模、冶金粉模、木工切削工具、冷切剪刀钻套及量规等工具。我们在研制中 ,经过反复探索和试验 ,制订了合理的冶炼工艺和特殊的锭模及锻造工艺 ,使材质组织达到均匀一致 ,另外对标准物质加工 ,大胆创新 ,采用双刀切屑新工艺 ,极大提高了功效 ,缩短了周期 ,降低了成本。
Cr1 2 is a high-carbon, high-chromium, austenitic steel, which is also widely used in cold-working die steel. The steel has better hardenability, wear resistance, hot workability. Carbide distribution in the steel better, can be used to create complex shapes, working conditions under a variety of cold-working die. Such as die-punch, thread rolling die, drawing die, die, metallurgical powder mold, woodworking cutting tools, cold cut scissors drill and gauges and other tools. We have been in the development, after repeated exploration and testing, developed a reasonable smelting process and special ingot and forging process, the material organization to achieve uniform, the other on the standard material processing, bold innovation, the use of double-chip cutting new technology, pole Large increase in efficiency, shorten the cycle and reduce costs.
