Product Description

Duplex 2205 Stainless Steel Pipe

We offer 2205 stainless steel pipe & tube in wide large of sizes, duplex 2205 possesses high strength and excellent corrosion resistance, so it can be applied in harsh environment, which other stainless steels can not replace, 2205 is the most used grade in duplex stainless steel, approx 60% for proportion.

2205 Stainless Steel Pipe & Tube Specifications

ASTM A789, ASME SA789
Seamless and Welded Ferritic/Austenitic Stainless Steel Tubing for General Service

ASTM A790, ASME SA790
General Requirements for alloy and Stainless Steel Pipe

Duplex 2205 Stainless Steel

2205 a duplex grade with a ferritic-austenitic microstructure, nearly 50% ferritic and 50% austenitic, containing contain larger amounts of chromium (22%), 5% nickel, 3.2% molybdenum and other alloying elements such as nitrogen and manganese, the high chromium, molybdenum and nitrogen contents provide good corrosion resistance, it is superior to 316/316L and 317L.
