Stainless Steel 310/310S/310H
Grade 310 is a medium carbon austenitic stainless steel, for high temperature applications such as furnace parts and heat treatment equipment. It is used at temperatures up to 1150°C in continuous service, and 1035°C in intermittent service. Grade 310S is a low carbon version of grade 310.
Application Industries
These materials are not a single material but the name for a family of corrosion resistant steels. Like many scientific breakthroughs, the origins of stainless steel lies in a lucky accident. From the smallest part of the zipper to the largest building skyscraper.
Metal fabrication is widely used across various industrial sectors such as mining, construction, manufacturing, shipbuilding, automotive, aerospace, and energy.
