Duplex Steel S32205
Duplex Steel S32205
Product Description
Duplex 2205 (UNS S31803 F51 /S32205 F60)/SAF 2205/Alloy 1.4462
Duplex 2205 is a two-phase, ferritic, austenitic 22% chromium, 3% molybdenum, 5 to 6% nickel alloyed stainless steel. It is the most widely used duplex stainless steel grade and is characterized by high yield strength, double that of the standard austenitic stainless steel grades. It also demonstrates good fatigue strength, as well as outstanding resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion in severe environments.
