不锈钢铸件，是用各种不锈钢材料生产的铸钢件总称，主要用于各种介质腐蚀条件下。
Stainless steel casting is the general name of steel castings produced with various stainless steel materials. It is mainly used under various medium corrosion conditions.
早在1910年就已发现，钢中的含Cr量超过12%时，就有良好的抗腐蚀和抗氧化性能。典型的不锈钢除含Cr12%以上外，还含有一种或多种其他合金元素，如Ni 、Mo、 Cu、 Nb、 Ti 和N2等。
As early as 1910, it has been found that when the Cr content in steel exceeds 12%, it has good corrosion and oxidation resistance. In addition to Cr12%, typical stainless steel also contains one or more other alloy elements, such as Ni, Mo, Cu, Nb, Ti and N2.
