2205 Duplex Stainless Steel Characteristics
Alloy 2205 (UNS S32305/S31803) is a duplex stainless steel composed of 22% chromium, 3% molybdenum and 5-6% nickel-nitrogen alloy. It offers high strength, excellent impact toughness, and superior overall and local stress corrosion resistance.
Key Advantages
Superior pitting and crevice corrosion resistance compared to 316L and 317L austenitic stainless steel
High corrosion resistance with lower thermal expansion coefficient and higher thermal conductivity
Twice the compressive strength of austenitic stainless steel, enabling weight reduction and cost savings
Excellent performance in temperature range of -50°F to +600°F
