白钢件就是不锈钢件，，0Gr18Ni9Ti.-00Gr17Ni14等，，是国标型号，，美标A316L,A304等。。。大连细密零部件加工中就是耐侵蚀钢，，就是铁铬镍的合金，，按金相组织分为，，铁素体，，奥氏体，，马氏体，，详细用途各不相同。。。

White steel parts are stainless steel parts, 0Gr18Ni9Ti- 00Gr17Ni14 and other models are national standard models, including American standard A316L and A304. In the processing of precision components in Dalian, corrosion-resistant steel is used, which is an alloy of iron chromium nickel. According to the metallographic structure, it can be divided into ferrite, austenite, and martensite, with different specific uses.
