Product Description

Material Summary

310 stainless steel is a highly alloyed austenitic stainless steel used for high temperature application. The high chromium and nickel content give the steel excellent oxidation resistance as well as high strength at high temperature. This grade is also very ductile and has good weld ability enabling its widespread usage in many applications.

Stainless Steel 310H is the preferred metal of choice for high temperature conditions out of the 310 Stainless Steel grades. It finds use in the heat treatment industry, including the containment of concentrated acids. 310H is often exposed to sulfur dioxide environments and displays a high level of resistance to negative effects, as well as those from oxidation at high temperatures. The metal also displays increased resistance against creep corrosion.
While 310S is the low carbon version of the 310 grades, 310H is the high carbon modification of the metal specifically designed for better resistance to creep, as aforementioned. Its resistance to corrosion in high temperature environments exceeds that of many other stainless steel alloys. However, it does not display the same resistance against aqueous corrosion. In wet environments, its high carbon content works as a limitation.
