Product Description
Product Description
The 310S type of the grade consists lower carbon content (about 0.08% max), while other composition remains the same. It is mainly used in high-ductility than high temperature strength applications. It is also used under wet corrosive environments at comparatively lower temperatures. The creep resistance enables the alloy to be used under thermal cyclic applications, also the alloy can be used in moderately carburizing, nitriding and sulphuric environments. Hence, it is widely used in chemical processing industries.
