What are Super Duplex Steel ASTM A790 UNS S32750 Pipes?

Super Duplex Steel ASTM A790 UNS S32750 Pipes is a high chromium, high molybdenum, high nitrogen containing ferritic-austenitic stainless steel pipe. It has a higher pitting resistance, crevice corrosion resistance, and stress corrosion cracking resistance due to its composition. It has a higher yield strength than common duplex grades of steel and thus finds its suitability especially in structural applications where high yield strength is needed. It finds its usage as a material of choice in aggressive environments due to its very high mechanical qualities as well as corrosion resistance.

Advantages of Super Duplex Steel ASTM A790 UNS S32750 Pipes?

One of the major advantages of Super Duplex Steel ASTM A790 UNS S32750 Pipes is its high ratio of strength to weight, which facilitates thinner material usage with superior mechanical characteristics.

• Outstanding Corrosion Resistance – Its high chromium and molybdenum levels give this pipe greater resistance to stress corrosion cracking and pitting due to chloride action.
• High-Tensile Strength – It provides almost double the yield strength of standard stainless steel, which maintains the structural integrity under harsh conditions.
• Exceptional Weldability – It has excellent weldability without sacrificing its high strength, minimizing fabrication issues.
• Cost-Effective Solution – Due to its long lifespan and less maintenance requirements, it proves to be an affordable option for different industries.
• Higher Thermal Stability – The pipe has high resistance to temperature and thus can withstand high temperature operations with pressure applications.
