2205 Duplex Stainless Steel Pipe

2205 Duplex Stainless Steel Pipe

Stainless steel pipe or tube is an alloy steel that is not easy to rust. Its surface is smooth and clean.  We have many stainless steel pipes in different specifications and different materials and it can be customized according to customer requirements

Products Description

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.
