UNS32750 S31803 Duplex Stainless Steel Pipe With Super Duplex 2507 Bright Annealed Surface

Production Name : Super Duplex Stainless Steel Pipes Size : 14'' We are Super Duplex Factory Specialized in Duplex 2250 /2507

Product Description

Duplex Steel appeared in the marketplace due to the need to combat the shortcomings of austenitic and ferritic steels. It was found that a mixture of these two materials resulted in higher strength, reduced weight, good weld ability and increased resistance to stress corrosion cracking.

Unlike similar steels, duplex also displays an improved resistance to localised corrosion, particularly pitting, crevice corrosion and stress corrosion cracking. Due to its ferritic qualities, duplex also shows very good resistance to stress corrosion cracking when compared to standard austenitic. In some cases, the strength of duplex stainless steel can be up to double that of the most commonly used grades of stainless steel.

Duplex – The Benefits

• Stronger than 300 series stainless steel which also brings weight advantages
• High resistance to pitting, crevice corrosion and stress corrosion cracking
• Higher heat conductivity and lower thermal expansion than austenitic steels

Duplex Uses

• Pipes for production and transportation of oil and gas
• Structural and mechanical components
• Heat exchangers
• Cooling pipes
