Stainless Steel 310 / 310S Pipe
High-Temperature Heat Resistant Stainless Steel Pipes
SS 310 Pipe is a high-chromium and nickel austenitic stainless steel designed for use in high-temperature corrosion-resistant applications. Grade 310S is the low-carbon version of 310, offering better weldability and preventing embrittlement in service. These pipes are capable of resisting oxidation up to 1100°C in mildly cyclic conditions, making them ideal for furnace parts and heat exchangers.
