Steelage Alloys LLP is involved in manufacturing, supplying and exporting a wide gamut of Duplex Steel Flanges(UNS S31803) in various sizes, dimensions and standards at market leading prices.Duplex Stainless Steel Flanges are often used in chemical processing, transport and storage – pressure vessels, tanks, piping, and heat exchangers.It has higher corrosion resistance than SS 316 in a wide variety of corrosive chemicals including sulphuric, phosphoric and nitric acids. Stress corrosion cracking occurs when stainless steels are subjected to tensile stress, while in contact with solutions containing chlorides.These Duplex Flanges (UNS S32205) are also offered to our patrons at customized sizes, dimensions and standards. Although 2205 has good high temperature oxidation resistance, this grade – like other duplex stainless steels – suffers from embrittlement if held for even short times at temperatures above 300 DegC.
