Duplex stainless steel flange contain alloying elements such as Mo, Cu, Nb, Ti, and N.

DUPLEX STEEL FLANGE PROVIDED BY YUHONG

Duplex stainless steel flanges are made from austenitic-ferritic stainless steel, which was designed to deliver higher strength and corrosion resistance than 300 series stainless steel.

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

SUPER DUPLEX STEEL FLANGES FEATURES

Duplex steel flanges 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.

YUHONG GROUP with 30 years of development and experience, now is the largest ss pipe manufacturer in China. We specialize in the production of Stainless Steel, Duplex Steel, Copper Nickel alloy steel, Nickel Alloy Steel pipe & tube, and related fitting & flange, etc. Our products are widely used in various important sectors like Mining, Energy, Boiler & Heat Exchanger, Petrochemical, Chemical Industry, Food plant, Paper plant, Gas and Fluid Industry, etc.
