Duplex Stainless Steel Pipe - China

We can produce and deliver nearly any duplex material requirement in

pipe, tube or fittings.

While Duplex 2205 is the most common duplex

product we supply, we can also deliver Duplex 2304 and Duplex 2207 with

reduced lead times as these alloys are stocked.

Alloy 2205 (UNS

S32305/S31803) is a 22% chromium, 3% molybdenum, 5-6% nickel, nitrogen

alloyed duplex stainless steel pipe with high general, localized, and

stress corrosion resistance properties in addition to high strength and

excellent impact toughness.

Alloy 2205 provides pitting and crevice corrosion resistance superior to 316L or 317L austenitic stainless steel tube in almost all corrosive media.

It also has high corrosion and erosion fatigue properties as well as lower thermal expansion and higher thermal conductivity than austenitic.

Standard: ASTM/ASME A789/SA789, A790/SA790

Steel Grade: UNS S32750, S31803, S32760 etc.

Applications:

General service, fluid transportation, pressure, high and low temperature, structural, heat exchanger, oil and gas service, ornamental, chemical and fertile

Duplex stainless steel 2205 has below capability:

High intensity and good impact toughness

It can bear stress corrosion well

Good ability to avoid patch and crack

Low heat expand modulus and better heat transmit

High pressure work

Weldable

Delivery requirment:

Marking: SunnySteel, material grade, standard, specification, heat no.
