  • Surface Treatment of Metal Casting Parts

    Surface Treatment of Metal Casting Parts

    Metal surface treatment is a process of artificially forming a surface layer on the surface of a metal base material that is different from the mechanical, physical and chemical properties of the base. The purpose of surface treatment is to meet the product's corrosion r...

  • Heat Treatment of Precipitation Hardening Stainless Steel Castings

    Heat Treatment of Precipitation Hardening Stainless Steel Castings

    Precipitation hardening (PH) martensitic stainless steel generally contains alloying elements such as copper, lead, molybdenum, and titanium that form a hardened phase. These alloying elements have greater solubility in austenite, but very little in martensite. Therefore...

  • Heat Treatment of Austenitic Stainless Steel Castings

    Heat Treatment of Austenitic Stainless Steel Castings

    The as-cast structure of austenitic stainless steel castings is austenite + carbide or austenite + ferrite. Heat treatment can improve the corrosion resistance of austenitic stainless steel castings.   Equivalent Grade of Austenitic Stainless Steel AISI ...
