ATSM A790 Duplex Stainless Steel Pipe S32750 Use of Oil and gas industry equipment

Product Discription:

ASTM A789 ASME SA 789 2507 UNS S32750 (EN 10216-5 1.4410) Stainless steel is a super duplex stainless steel containing 25% chromium, 4% molybdenum and 7% nickel, designed for demanding applications requiring extremely high strength and corrosion resistance, such as chemical processes. Petrochemical and seawater equipment. It has excellent corrosion resistance to various media, due to its high chromium, molybdenum, nitrogen content, has excellent pitting and crevice corrosion resistance in seawater and other chlorine-containing environments, and the critical corrosion temperature exceeds 50℃. The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity and low coefficient of thermal expansion. Compared to 300 Series austenitic stainless steel or conventional duplex alloys, S32750 stainless steel offers enhanced resistance to pitting and crevice corrosion. This can be attributed to the increased amounts of chromium, molybdenum and nitrogen found in these materials. Alloy 2507 is the most common "super" biphase grade.

The characteristics of Duplex 32750:

• High resistance to chloride stress corrosion cracking
• High Strength
• Superior resistance to chloride pitting and crevice corrosion
• Good general corrosion resistance
• Suggested for applications up to 600° F
• Low rate of thermal expansion
• Combination of properties given by austenitic and ferritic structure
• Good weldability and workability

Use of S32750 duplex stainless steel:

Sea Water Desalination plants and pumps, Petrochemical industries, Oil & Gas Industry,

Fertilizer plant, Power Industry, Mining Extraction systems, Sewage
