白鋼件就是不銹鋼件，0Gr18Ni9Ti.-00Gr17Ni14等，是國標型號，美標A316L,A304等。大連精密零部件加工中就是耐腐蝕鋼，就是鐵鉻鎳的合金，按金相組織分為，鐵素體，奧氏體，馬氏體，具體用途各不相同。

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.
