  • As one of the leading industrial flanges manufacturers in China, Yuhong Group can do ASTM A182/ASME A182 flange super duplex with material grades S31803, S32750, S32760, etc.

Super Duplex Steel Flanges Features

  • Duplex steel has the characteristics of both austenitic and ferritic stainless steel. Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, and significantly improved intergranular corrosion resistance and welding performance.

  • At the same time, the flange super duplex also maintains the 475 ℃ brittleness and high thermal conductivity of ferritic stainless steel and has the characteristics of superplasticity.
