S31803 2205 f51 din1.4462 is a ferritic-austenitic duplex stainless steel . It provides a valuable combination of high strength, excellent corrosion resistance and stress-corrosion cracking resistance as well as very good pitting resistance. In addition, it is highly resistant to stress and provides a low level of thermal expansion. These materials have a variety of applications that include heat exchangers, piping, pressure vessels, tanks, fans, rotors, pulp and paper production equipment, oilfield equipment and press rolls. Standard: astm a276, a479, a182. We offer the materials in form of stainless steel round rod, stainless steel square bar, stainless steel wire rod, stainless steel forging, stainless steel flat strip, stainless steel forged cylinder, stainless steel forged ring, stainless steel forged tube sheet.
S32750 2507 f53 din1.4410 is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel. The high chromium, molybdenum and nitrogen levels provide excellent resistance to pitting, crevice and general corrosion. This material has excellent resistance to chloride stress corrosion cracking, high thermal conductivity and a low coefficient of thermal expansion, further, the impact strength is also high. These materials are designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment. Standard: astm a479, a182. We offer the materials in form of stainless steel round rod, stainless steel square bar, stainless steel hexagon bar, stainless steel wire rod, stainless steel forging, stainless steel flat strip, stainless steel forged cylinder, stainless steel forged ring, stainless steel forged tube sheet.
