Stainless Steel Investment Castings

The Stainless Steel casting process produces very little waste and is often the preferred method for avoiding the high costs of Stainless Steel. Stainless Steel investment castings can achieve high levels of corrosion and abrasion resistance without plating or machining, thereby making it one of the most investment casting friendly metals available.
