2205 Duplex Stainless Steel

2205 Duplex Stainless Steel

Duplex 2205 (UNS S32205, UNS S31803, EN 1.4462, SAF 2205, X2CrNiMoN22-5-3) is the most widely used duplex stainless steel grade and is characterized. Its yield strength is twice that of austenitic stainless steel. This feature allows designers to reduce weight when designing products, making this alloy more advantageous than 316 and 317L. Gnee offers high-quality duplex stainless steel in a wide range of grades and sizes, with ample inventory. Contact us for a quotation!

The main chemical composition of 2205 duplex stainless steel is 22% chromium, 4.5% nickel, 2.5% molybdenum and other alloying elements. It has high resistance to stress corrosion cracking and high mechanical strength. Excellent resistance to stress corrosion cracking, crevices, pitting, erosion and general corrosion in harsh environments.
