What is ASTM A276 UNS S32750 Super Duplex Round Bar ?
UNS S32750 stainless steel round bar is an austenite-ferrite duplex stainless steel (equivalent to grades 2507 and F53), which belongs to the third generation of duplex steel. Its strength is 2.7 times that of 304 stainless steel, and its fatigue resistance is improved by 30%. Its pitting equivalent PREN≥40 and Cl⁻ concentration resistance is up to 200,000ppm, which is superior to 2205 duplex steel and 904L stainless steel, and meets the requirements of LNG cryogenic, high temperature and high pressure working conditions.
In addition, GNEE provides ASTM A276 material certificate, NACE MR0175 anti-sulfur certification, and supports API 6A/ASME BPVC standards.
