Stainless Steel 310S Forged Threaded Fittings has excellent strength and toughness at cryogenic temperatures. Heat resistant SS 310S Forged Socket Weld Fittings have poor agreement between different specification systems. SS 310S Forged Threaded Tee Fittings is great for use in elevated temperature and sulfur-bearing gas environments. SS 310S Forged Socket Weld Tee Fittings is superior to Stainless Steel 304 Forged Fittings and Stainless Steel 309 Forged Fittings in most environments. SS 310S Forged Threaded Elbow Fittings does not respond to heat treatment. Heat this SS 310S Forged Socket Weld Elbow Fittings from 1050 Deg C to 1150 Deg C and water quench. This treatment in Stainless Steel 310S Forged Threaded Cross is not required for high temperature service, but welding slag should be thoroughly removed. Cold forming of pieces with long-term exposure to high temperatures is not recommended since Stainless Steel 310S Forged Socket Weld Cross Fittings is subject to carbide precipitation and sigma phase precipitants.
LIST OF STAINLESS STEEL 310S FORGED FITTINGS
Stainless Steel 310S Forged Threaded Reducer Fittings will be sensitized to intergranular corrosion after service at temperatures in range 550 ° C – 800 ° C. SS 310S Forged Socket Weld Reducer has good characteristics suited to all standard methods. Stainless Steel 310S Forged Threaded Cap has outstanding resistance to creep deformation and environmental attack. SS 310S Forged Socket Weld Cap maintains very good corrosion resistance and also has exceptional resistance to oxidizing and carburizing atmospheres.
