What is Stainless Steel Investment Castings?
Stainless steel investment casting is a dewaxing investment casting process in which molten stainless steel material is poured into a mold and allowed to solidify, resulting in a solid stainless steel casting in the desired shape.
When we have requirements for the properties and corrosion resistance of steel. Stainless steel castings are a better choice.
Advantages of Stainless Steel Castings
01 Excellent wear and corrosion resistance
02 High temperature and pressure resistance
03 Excellent surface finish
04 High dimensional accuracy
05 Extremely complex parts can be cast
06 Almost any metal can be cast
07 No flash or mold lines
