Alloy 446 Stainless Steel
High chromium ferritic stainless steel used in high heat applications.
Applications
Alloy 446 stainless steel is used to make parts and equipment that require excellent high temperature resistance to oxidation and corrosion. 446 stainless steel pipe and fittings are often found in burners, boiler parts, thermocouple protectors, injector nozzles in molten compounds, flame rods and metal to glass bonding parts.
Properties
Alloy 446 stainless steel is a high chromium ferritic stainless steel commonly used in high temperature applications from 1500 °F to 2200 °F. 446 stainless steel is the most oxidation resistant steel among the 400 series stainless’. Its resistance to cyclic oxidation is equal to or better than 309 and 310 steels, but has lower strength at elevated temperatures.
