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 delivers exceptional strength, impact toughness, and comprehensive corrosion resistance.

Key Advantages

Superior Corrosion Resistance: Outperforms 316L and 317L austenitic stainless steel in pitting and crevice corrosion resistance.
High Strength: Twice the compressive strength of austenitic stainless steel, enabling weight reduction and cost savings.
Thermal Properties: Lower thermal expansion coefficient and higher thermal conductivity compared to austenitic grades.
Temperature Range: Optimal performance between -50°F to +600°F, with considerations for welded structures beyond this range.
