Duplex Stainless Steel Lined Pipe - China

Liner: 2205 (S31803), 2506 (S31804, S32740), 2507···Etc;

Backing: API 5L, API 5CT, ASTM, ASME···Etc Duplex stainless steel (DSS) refers to the ferrite and austenite each accounted for about 50% of the content is generally less phase also need to reach at least 30% of the stainless steel.

Because the characteristics of two-phase structure, by properly controlling the chemical composition and heat treatment process, so that duplex stainless steel combines advantages of austenitic stainless steel and ferritic stainless steel.

The duplex stainless steel has a combination of high strength and resistance to chloride stress corrosion of ferritic stainless steel and excellent toughness and weldability of austenitic stainless steel, it is these superior properties make duplex stainless steel as a structural materials welded rapid development, since the 1980s has be juxtaposed with martensitic, austenitic and ferritic stainless steel.
