ASTM A790 Uns S32750 High Strength Dual Phase Hot Rolled 18inch Sch80 Od. 457.2mm ISO9001 Certificate Stainless Steel Pipe
S32760 stainless steel is a high alloy super duplex stainless steel with strong steel strength and corrosion resistance, and excellent comprehensive performance.S32760 (F55, 1.4501) is a high alloy super duplex stainless steel mainly used in various highly corrosive environments. S32760 dual phase steel has strong strength and corrosion resistance, mainly used in chemical processing, petrochemical industry, and underwater equipment. It has strong resistance to chloride corrosion, high thermal conductivity, and low coefficient of thermal expansion. The high content of chromium, molybdenum, and nitrogen gives it high resistance to spot corrosion, crack corrosion, and other corrosion. The excellent comprehensive properties of S32760 dual phase steel are superior to ordinary dual phase steel, such as 2205, S31803, etc.
S32760 dual phase steel is resistant to various inorganic and organic acids, and its added copper element gives it excellent resistance to non oxidizing acid corrosion. S32760 is also resistant to strong alkaline corrosion
2, Physical properties of S32760 super duplex stainless steel:
Density: 8.0g/cm3, melting point: 1400-1450 ºC, specific heat (J/kg K): 460, resistivity( μ Ω cm): 90.0, thermal conductivity (W/m K): 12.8
3, S32760 super duplex stainless steel mechanical properties: tensile strength: σ B ≥ 750Mpa, yield strength σ B ≥ 550Mpa: Elongation: δ≥ 45%, hardness: 270 (HB)
4, S32760 Super Duplex Stainless Steel Material Characteristics:
Reliable corrosion resistance (resistance to pitting coefficient (PREN ≥ 40), excellent resistance to chloride ion pitting and crevice corrosion, excellent resistance to sulfur acidity, excellent resistance to stress corrosion cracking in chloride ion and acidic (such as hydrogen sulfide) media environments, resistance to erosion corrosion and corrosion fatigue, excellent mechanical properties, and good weldability.
5, The main applications of S32760 super duplex stainless steel are:
Neutral chloride environment, refining industry, petrochemical and chemical industry, transportation pipelines for chemical industry, petroleum and natural gas industry, pulp and paper industry, fertilizer industry, urea industry, phosphate fertilizer industry, seawater environment, energy and environmental protection industry, light industry and food industry, equipment for food and pharmaceutical industry, high-strength structural components, submarine pipelines, flue gas desulfurization, osmotic desalination equipment, sulfuric acid plants, Marine engineering fasteners, etc.
