Product Description

 
Production Name : Seamless Duplex Stainless Steel Pipe Standard : ASTM A790 Material : S31803 NACE MR0175

 
 
 

MATERIAL DESCRIPTION

 
Duplex UNS S31803 is the most common duplex grade in the market. It has very good resistance to localized corrosion and stress corrosion cracking in combination with high mechanical strength. It is widely used in oil & gas, hydro power, pressure vessels, pulp & paper, structural components and chemical tankers. The alloy is not intended to be used at temperatures above 300°C due to embrittlement.

APPLICATIONS

The main applications are for details with special requirements for high corrosion resistance.
S31803 is characterized by:
• High resistance to stress corrosion cracking in halide containing environments.
• High resistance to pitting and crevice corrosion.
• High resistance to general corrosion.
• High mechanical strength.
• High resistance to erosion corrosion and corrosion fatigue.
