ASTM A276 310S Stainless Steel Round Bar Manufacturer & Supplier
We are a professional manufacturer of ASTM A276 310S stainless steel round bar,310S is a low-carbon austenitic stainless steel ,With a high content of chromium (24-26%) and nickel (19-22%), 310S stainless steel offers superior corrosion resistance and high temperature resistance compared to lower alloyed grades.
This grade is known for its behavior of corrosion resistance at high temperature. The additions of carbon are optimized in order to improve its creep deformation resistance. The steel can easily be welded. AISI 310S is projected for high temperature applications, up to 1100°C, in oxidating atmospheres.The steel can also be used under conditions of slightly oxidating atmosphere, nitriding, cementation and sulfuring as well as with thermal cycles, although temperature must be reduced.
We stock and supply 310S round bars in various finishes and sizes, suitable for petrochemical, thermal processing, and furnace applications.
Type 310S is a high temperature chromium nickel austenitic stainless steel with high creep strength that resists oxidation at temperatures up to 2000˚F in dry air.
310 is a highly alloyed austenitic stainless steel used for high temperature applications. The high chromium and nickel contents give the steel excellent oxidation resistance and excellent strength at high temperatures. This grade is also very ductile and has good weldability enabling its widespread usage in many applications.310S, due to its lower carbon content, is recommended for applications where sensitisation and subsequent corrosion by high temperature gases or condensates.
