ASTM A790 S31803 Duplex Seamless And Welded Pipe Corrosion Resistant

ASTM A790 S31803 Duplex Seamless And Welded Pipe Corrosion Resistant

UNS S31803, F51, 1.4462 duplex stainless steel is designed to combine improved resistance to stress corrosion cracking, pitting, crevice corrosion and high strength when compared with other stainless alloys.

These attributes mean that Duplex UNS S31803, F51, 1.4462 can be used successfully as an alternative to standard stainless steel specifications in applications where higher strength and resistance to stress corrosion cracking is required.

Duplex Stainless Steel Features

Duplex stainless steels have Austenitic and Ferritic stainless steel microstructure, and possess properties in two groups stainless steel, however, there are different.

Versus Austenitic

Higher yield strength
Greater corrosion resistance
Stress corrosion cracking resistance
Not common, used temperate under 250 C.
Fabricability not good as Austenitic
Strictly control heat treatment and welding process
Price stability

Versus Ferritic

Good toughness than Ferric, not hard
Greater corrosion
Fabricability is better
Better weldability
Wide usage than Ferritic
Higher price

APPLICATIONS:

· Chemical processing, transportation and storage

· Oil and gas exploration and offshore drilling rigs

· Oil and gas refining

· The marine environment

· Pollution control equipment

· Pulp and paper manufacturing

· Chemical process plant
