Product Introduction

Duplex 2205 Pipe refers to a pipe made of austenite and ferrite. Duplex S32205 contains high chromium, which is good for oxidizing acids, and sufficient molybdenum and nickel to resist corrosion in moderately reducing acidic media. Duplex 1.4462 is much more resistant to chloride stress corrosion cracking than austenitic stainless steel 304 or 316. We are a duplex steel pipe supplier with 15+ export experience. We can provide Duplex 2205 seamless pipe and welded pipe. Contact us for more information and free quotes!

2205 Duplex Stainless Steel Structure

Nickel is an element that stabilizes austenite. Nickel promotes the crystal structure of stainless steel from body-centered cubic structure (ferrite) to face-centered cubic structure (austenite).
