ASTM A790 UNS S31803 Pipe
Super Duplex Stainless Steel is a highly alloyed, good performance duplex steel with a pitting resistance. Super duplex offers good resistance to pitting and crevice corrosion.Super duplex is suited for use in aggressive environments. It has good resistance to stress corrosion cracking in chloride and sour environments and has good resistance to erosion corrosion and corrosion fatigue.
Application:
Oil and gas industry equipment.
Offshore platforms, heat exchangers, process and service water systems, fire - fighting systems, injection and ballast water system.
Chemical process industries, heat exchangers, vessels, and piping.
Desalination plants, high pressure RO - plant and seawater piping.
Mechanical and structural components, high strength, corrosion - resistant parts.
power industry FGD systems, utility and idustrial scrubber systems, absorber towers, ducting, and piping.

2507 should be hot worked between 18750F and 22500F. This should be followed by a solution anneal at 19250F minimum and a rapid air or water quench.
Cold Forming:
Most of the common stainless steel forming methods can be used for cold working 2507. The alloy has a higher yield strength and lower ductility than the austentic steels so fabricators may find that higher forming forces, increased radius of bending and increased allowance for springback are necessary. Deep Drawing, stretch forming and similar processes are more difficult to perform on 2507 than on an austenitic stainless steel. When forming requires more than 10% cold deformation, a solution anneal and quench are recommended.
Heat Treatment:
2507 should be solution annealed and quenched after hot or cold forming solution annealing should be done at a minimum of 19250F. (1025 - 1125 centigrade) Annealing should be followed immediately by a rapid air or water quench to obtain maximum corrosion resistance, heat treated products should be pickled and rinsed.
Welding:
2507 possesses good weldability and can be joined to itself or other materials by shielded metal arc welding, gas tungsten arc welding, plasma arc welding, flux cored wire or submerged arc welding. 2507/P100 filler metal is suggested when welding 2507 because it will produce the appropriate duplex weld structure.

What is ASTM A790 uns S31803 material?
STM 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.What is a material equivalent to uns S31803?
S31803 is a duplex stainless steel based on a chromium content of 22% and can also be referenced as DIN 1.4462 and ASTM A182 F51 when supplied as round bar.Is S31803 the same as 2205?
Duplex S31803, also known as stainless steel grade 2205, is a standardized formulation that conforms to UNS specification regulations. Its temperature range is typically listed as -50° to 300° C (-58° to 572° F); outside of this range, its performance characteristics degrade.Material Standards And Grades ASTM A790 UNS S31803 Pipe
