Why stainless steel castings have good corrosion resistance

Stainless steel castings are steel castings made of various stainless steel materials, which are mainly used for corrosion of various media. Stainless steel castings are made of stainless steel, so what is the corrosion resistance of stainless steel castings?

The corrosion resistance of stainless steel castings depends on chromium, but chromium is one of the components of steel, so the protection method is different. When the chromium addition amount reaches 10.5%, the atmospheric corrosion resistance of the steel is significantly improved, but when the chromium content is high, although the corrosion resistance is improved, it is not obvious. The reason is that when steel is alloyed with chromium, the type of surface oxide becomes a surface oxide formed by pure chromium metal. This tightly attached chromium-rich oxide protects the surface and prevents further oxidation.

The corrosion resistance of stainless steel castings is still very good. If you need stainless steel castings, you can contact us Hongzhe Precision Casting. We have various casting methods.
