Description

Duplex 2205 (UNS S31803 F51 /S32205 F60)/SAF 2205/Alloy 1.4462

S32205 duplex stainless steel 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. S32205 stainless steel also demonstrates good fatigue strength, as well as outstanding resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion in severe environments.
