2507 Duplex stainless steel round bar/rod is a super duplex stainless steel bar, composed of austenite and ferrite, with high strength and excellent corrosion resistance. Its high content of chromium (about 25%), nickel (about 7%) and molybdenum (about 4%) makes it show excellent resistance to stress corrosion cracking, pitting and crevice corrosion in chloride environments.
The mechanical strength of 2507 duplex stainless steel round bar/rod is significantly higher than that of ordinary austenitic stainless steel, and it has good weldability and machinability. It is widely used in oil and gas, chemical industry, marine engineering, seawater treatment and other fields, especially suitable for highly corrosive media and high strength requirements. It is an efficient and economical choice.
