2205 Duplex Stainless Steel Plate

Duplex 2205 is a two-phase, ferritic, austenitic, 22% chromium, 3% molybdenum, 5% to 6% nickel alloy stainless steel. It is the most widely used duplex stainless steel grade and is characterized by high yield strength, which is twice that of standard austenitic stainless steel grades. It also exhibits good fatigue strength and excellent resistance to stress corrosion, cracking, pitting, erosion and general corrosion in harsh environments.
