产品说明
产品参数

7Mn15Cr2Al3V2WMo鋼是一種高M(jìn)o-V系無(wú)磁鋼。該鋼在各種狀態(tài)下都能保持穩(wěn)定的奧氏體，具有低的磁導(dǎo)系數(shù)，高的硬度、強(qiáng)度，較好的耐磨性。

產(chǎn)品介紹

由于高錳鋼的冷作硬化現(xiàn)象，切削加工比較困難。采用高溫退火工藝，可以改變碳化物的顆粒尺寸、形狀與分布狀態(tài)，從而地改善鋼的切削性能。采用氣體軟氧化工藝，進(jìn)一步提高鋼的表面硬度，增加耐磨性，顯著提高零件的使用壽。該鋼適于制造無(wú)磁模具、無(wú)磁軸承及其它要求在強(qiáng)磁場(chǎng)中不產(chǎn)生磁感應(yīng)的結(jié)構(gòu)零件。此外，由于此鋼還具有高的高溫強(qiáng)度和硬度，也可以用來(lái)制造在700℃～800℃以下使用的熱作模具。
