Product Description

Duplex Steel S32205 Slip on Flanges uses biphasic steel as raw material for production, the so-called biphasic stainless steel is in the solid solution of its ferrite phase and austenitic phase about half, the general amount of small phase content also needs to reach 30%. When the content of C is low, the content of Cr is 18%-28% and the content of Ni is 3%-10%.

Some steels also contain Mo, Cu, Nb, Ti, N and other alloying elements. This kind of steel has the characteristics of austenitic and ferritic stainless steel, compared with ferrite, plasticity, toughness is higher, no room temperature brittleness, intergranular corrosion resistance and welding performance are significantly improved, but also maintain the ferritic stainless steel 475℃ brittleness and high thermal conductivity, with superplasticity and other characteristics. Compared with austenitic stainless steel, it has higher strength and better resistance to intergranular corrosion and chloride stress corrosion. Duplex stainless steel has excellent corrosion resistance, is also a nickel nickel stainless steel.

Performance and Features of Duplex Steel S32205 Slip on Flanges

1. Yield strength is more than twice as high as that of ordinary austenitic stainless steel, and it has enough plastic toughness required for molding.

2. Excellent stress corrosion rupture resistance, especially in chloride ion environment.

3. Super duplex steel has very high corrosion resistance, in some media, such as acetic acid, formic acid and even higher can replace high alloy austenitic stainless steel, and even corrosion resistant alloy

4 has good local corrosion resistance, compared with the alloy content of austenitic stainless steel, its wear corrosion resistance and fatigue corrosion performance are better than austenitic stainless steel
