Features and application scope:

1Cr17Ni2钢属于马氏体型不锈耐酸钢,具有较高的强度和硬度。

1Cr17Ni2钢对氧化性的酸类(一定温度、浓度的硝酸、大部分的有机酸),以及有机酸水溶液都有良好的耐腐蚀性能,适宜制造在腐蚀介质作用下的塑料模具和透明塑料制品模具等。但该钢焊接性能不好,易产生裂纹,制造模具时,不宜进行焊接。

1Cr17Ni2 steel is a martensitic stainless and acid resistant steel with high strength and hardness.

1Cr17Ni2 steel has good corrosion resistance to partially oxidizing acids and organic acid aqueous solution at a certain temperature. It is suitable for manufacturing plastic molds and transparent plastic product molds under the action of corrosive media. However, the steel has poor welding performance and is easy to produce cracks. It is not suitable to weld when manufacturing molds.
