白钢件就是不锈钢件，0Gr18Ni9Ti.-00Gr17Ni14等，是国标型号，美标A316L,A304等。大连精密零部件加工中就是耐腐化钢，就是铁铬镍的合金，按金相组织分为，铁素体，奥氏体，马氏体，具体用途各不相同。

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.
