Heat Treatment of Stainless Steel | KI Castings

Stainless steel is one of the most widely used alloys in metal casting — prized for its strength, hardness, and resistance to corrosion. But unlike other metals, the end of the casting process does not necessarily mean the product or component is market-ready. Heat treatment after stainless steel casting is often required to achieve the desired qualities of the finished product.
