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. Dalian precision parts processing is corrosion-resistant steel, 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.
