Duplex 2205 Stainless Steel

Duplex 2205 stainless steel is an advanced quality stainless steel alloy that contains at least 22% chromium, 6% nickel, and 3% molybdenum. SAF 2205 material provides incredibly good strength against fatigue and excellent corrosion protection against pitting, erosion, cracking, and more. This stainless steel alloy also provides superior mechanical strength than lower grade alloys, with approximately twice the proof of strength of austenitic stainless steel. In addition, Duplex 2205 material performs well up to 600°F and offers excellent workability and weldability.
