DUPLEX STAINLESS STEEL PIPE

ASTM A790 UNS S31803 is a specification in duplex steel material. The material is an alloy of steel with chromium and molybdenum in it. The addition of these materials makes the pipes stronger and much corrosion resistant. The SA 790 UNS S31803 one of the super duplex grades which is stronger and corrosion resistant.

Super Duplex pipes are made from a form of austenitic-ferritic stainless steel, based upon iron with alloying additions of chromium, nickel and molybdenum. As such, Super Duplex pipes are pipes made out of this material.

ASTM A790 UNS S32205 is a duplex steel type that is a mixture of different elements. There are chromium, molybdenum and nitrogen in the composition of SA 790 UNS S32205 steel material. The composition calls for corrosion resistance and strength in the mid-range among the other duplex steel types.

ASTM A790 UNS S32750(Duplex 2507) is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel, it can be the Seamless and Welded Ferritic/Austenitic Stainless Steel Pipe.

ASTM A790 UNS S32760 is a super duplex grade which contains 25% chromium, 4% molybdenum and 7% nickel in its composition. The composition makes the pipe stronger and corrosion resistant. The SA 790 UNS S32760 is therefore used in acidic environments where corrosion is high.

Duplex 2205 is used in environments where resistance to general corrosion and chloride stress corrosion cracking is important. Duplex 2205D is used in environments where resistance to general corrosion and chloride stress corrosion cracking is important.

Duplex Steel UNS S32950 Tube designed for high strength, stress corrosion cracking, resistance to pitting, erosion corrosion and corrosion fatigue. Duplex pipes and tubes used in various application industries like chemical, refineries, power plant, nuclear plant, construction etc.
