2205 Duplex Stainless Steel Coil | 022Cr22Ni5Mo3N Duplex Stainless Coil

Duplex structure of ferrite + austenite, much higher strength than ordinary austenitic stainless
Outstanding resistance to chloride pitting & stress corrosion cracking
Good toughness, fatigue resistance and weldability
Lower thermal expansion coefficient than austenitic stainless steel
Ideal choice for heavy corrosive offshore, oil & gas and desalination equipment

Product Overview

2205 duplex stainless steel coil GB grade 022Cr22Ni5Mo3N, AISI 2205, EN1.4462 (X2CrNiMoN22-5-3). This duplex grade combines ferrite and austenite dual phase structure. It has higher yield strength and far better chloride stress corrosion resistance than conventional 304 / 316L austenitic stainless steel.

We can supply hot rolled and cold rolled 2205 stainless coil, surface No.1 / 2B. Custom slitting service for narrow stainless steel strip. Widely applied in offshore platform equipment, oil & gas pipeline, seawater desalination, chemical reactor, pulp and paper industry.
