Product Description

UNS S32205 SAF2205 S22253 022Cr23Ni5Mo3N Duplex steel seamless pipe and tube 

Product Description

Material Summary
Duplex S32205 are the most common duplex grades in the market. They have very good resistance to localized corrosion and stress corrosion cracking in combination with high mechanical strength. They are widely used in oil & gas, hydro power, pressure vessels, pulp & paper, structural components and chemical tankers. The alloys are not intended to be used at temperatures above 300°C due to embrittlement
