Super Duplex Stainless Steel Welded/Seamless Pipes ASTM A790 UNS S32760

Super Duplex UNS S32760 Characteristic

S32760 super duplex stainless steel is developed to be used in aggressive environments. Properties of S32760 include toughness, high strength, corrosion resistance in a large number of organic and inorganic acids. Finally it features high resistance to strong alkalis and resists corrosion in a number of non-oxidizing acids. While involving extended exposure to temperatures more than 572F use of S32760 is not recommended. The chemical composition of UNS S32750 and UNS S32760 are similar; however, the latter contains slightly more copper and tungsten. The copper content (min. 0.5, max 1.0) permits excellent resistance to corrosion in many non-oxidizing and mineral acids like hydrochloric and sulfuric acid

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

Use

Chemical processing, transport and storage Oil and gas exploration and offshore rigs
Oil and gas refining
Marine environments
Pollution control equipment
Pulp & paper manufacturing
Chemical process plant
