Description

Duplex Stainless Steel Pipes ASTM A789 S31803 19.05*1.65 for Chemical Process Plant

UNS S31803 is a duplex grade with a ferritic-austenitic microstructure. The alloy consists of around 40-50% ferrite in the annealed condition. The duplex microstructure has the high strength of the ferritic grades whilst retaining the corrosion resistance of the austenitic grades.

YUHONG SPECIAL STEEL deal with Austenitic Stainless Steel, Nickel Alloy Steel(Hastelloy , Monel, Inconel, Incoloy ) seamless and welded pipe and tube already more than 25 years, every year sell more than 80000 tons of steel pipe and tube.
