This alloy is a high chromium-nickel corrosion-resistant martensitic stainless steel. It is extremely corrosion resistant and offers very good strength and toughness. It is typically used in aerospace and defence applications or where higher mechanical properties than 410<\/a> are required and where corrosive conditions are not too severe.<\/p>

The grade is generally supplied in the hardened and tempered condition. This grade is one of the most corrosion resistant grades of martensitic stainless steels, displaying excellent strength and toughness, resistance to stress corrosion and to oxidation up to 800\u00b0C.<\/p>

316H<\/a> stainless steel is a high-carbon, high-temperature variant of 316<\/a>, combining enhanced tensile strength at elevated temperatures with excellent corrosion resistance. It is widely used in power generation, chemical processing, aerospace, and industrial applications where both high strength and corrosion resistance are essential.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t
