Overview
Grade 310 Stainless Steel Tubes or UNS S31000 Tubes is one of the most widely used grades of heat-resistant stainless steel having good strength and oxidation resistance in continuous service temperatures up to 2000 Deg F (1093 Deg C). The key properties of this material are its high chromium and medium nickel content making its resistance to oxidation, sulfidation and other forms of hot corrosion its main characteristics.
It has resistant to resist high temperatures and can be preferred for heat treatment equipment and furnace. The SS 310 is mixture of manganese, carbon, phosphorus, silicon, chromium, sulfur, nickel, molybdenum, nitrogen material. This mixture gives unique strength and features.
