ASTM A789 UNS S31803 tube

Duplex 2205 Seamless Welded Tube and Super Duplex Seamless Welded Tube.

We are a recognised supplier of ASME SA 789 UNS S32205 tube in India

The ASTM A789 standard specification covers ferritic austenitic stainless steel in duplex and super duplex seamless welded tube for high temperature service like water heaters. .

ASTM A789 Duplex Seamless Welded Tube

ASTM A789 Tube

ASTM A789 is ferritic-austenitic stainless steel with good abrasion and erosion resistance. These duplex tubes have have wall thickness of 0.08mm-15mm with outer diameter 0.3mm-10mm in hardness form as soft, hard, half hard, etc.

As a stockist, we offer SA 789 S32750 seamless and welded stainless steel tubing use for services requiring general corrosion resistance

Scope And Manufacturing

ASTM A789 specification covers seamless tube and welded tube of duplex and super duplex (UNS S32205, UNS S31803, UNS S32760, UNS S32750)stainless steel. These Duplex steel tube are more prone to precipitation of sigma phase, nitrides and carbides than corresponding austenitic steels, causing embrittlement and reduced corrosion resistance. The formation of intermetallic phases such as sigma phase occurs in the temperature range 600-1000°C and decomposition of ferrite occurs in the range 350-500°C (475°C embrittlement). The high tensile strength of duplex steel tube also implies high fatigue strength. Due to their high chromium content, duplex steels offer excellent corrosion resistance in many media.
