Duplex Steel Buttweld Fittings

Duplex Steel Buttweld Fittings
Stub End Short Pattern 12" Sch40 Super Duplex SS2507 UNS S32750
Duplex steel buttweld fittings have better resistance to sea water than stainless steel grade 316 pipe fittings, and so as the mechanical properties.

We offer a complete range of butt weld elbow, tee, reducer, bend, cap, cross and stub end, which are available in various size, specification, thickness and shapes for meeting customer’s requirements.

Duplex Steel are known by it’s highly corrosion resistance properties with respect to the standard austenitic grades or high alloyed ferrite.

What is the Duplex Steel Grades?
ASTM A815 UNS S31803 Buttweld Fittings
People described 31803 as a duplex stainless steel with a microstructure of 50:50 austenite and ferrite. The steel combines good mechanical strength (typically up to over 480 MPa yield strength) and ductility with moderate to good corrosion resistance in a variety of environments.

ASTM A815 UNS S32205 Buttweld Fittings
2205 is a duplex stainless steel, with a chemical composition of nearly equal proportions of austenite and ferrite. This combination allows the alloy to be stronger and tougher than standard austenitic steels.
