Product Description Product Description IntroductionLORK is a special stainless steel manufacturer with 20 years of manufacturing experience. Stainless steel Super Duplex 2507 is designed to handle highly corrosive conditions and situations were high strength is required. High molybdenum, chromium and nitrogen content in Super Duplex 2507 help the material withstand pitting and crevice corrosion. The material is also resistant to chloride stress corrosion cracking, to erosion corrosion, to corrosion fatigue, to general corrosion in acids. This alloy has good weldability and very high mechanical strength.Duplex Stainless 2507 Applications ? Oil and gas industry equipment? Offshore platforms, heat exchangers, process and service water systems, fire-fighting systems, injection and ballast water systems? Chemical process industries, heat exchangers, vessels, and piping? Desalination plants, high pressure RO-plant and seawater piping? Mechanical and structural components, high strength, corrosion-resistant parts? Power industry FGD systems, utility and industrial scrubber systems, absorber towers, ducting, and piping2507 Standards2507 -S32750-SAF2507-00Cr25Ni7Mo4N ASTM/ASME ...….

The interpass weld temperature should not exceed 300°F or the weld integrity can be adversely affected. The root should be shielded with argon or 90% N2/10% H2 purging gas for maximum corrosion resistance. The latter provides better corrosion resistance.Chemical CompositionElementContent (%)Chromium, Cr24 - 26Nickel, Ni6 - 8Molybdenum, Mo3 - 5Manganese, Mn1.20 maxSilicon, Si0.80 maxCopper, Cu0.50 maxNitrogen, N0.24 - 0.32Phosphorous, P0.035 maxCarbon, C0.030 maxSulfur, S0.020 maxIron, FeBalanceMechanical PropertiesUltimate Tensile Strength, ksi116 min.0.2% Offset Yield Strength 0.2%, ksi80 min.0.1% Offset Yield Strength 0.2%, ksi91 min.Elongation in 2 inches, %15 min.Hardness Rockwell C32 max.Impact Energy, ft.-lbs.74 min.Available Sizes And Specification2507/S32750 stainless steel coil sizes and specificationsGrade2507/S32750Cold rolled stainless steel coilThickness: 0.3mm- 3.0mm, Width: 1000mm - 2000mm,Surface: 2B/BA/SB/8K/HL/1D/2D etcHot rolled stainless steel coilThickness: 3.0mm - 16mm, Width: 1000mm - 2000mmSurface: No.1/picklingStandardASTM A240/A480, ASTM B688, ASTM B463/SB463, ASTM B168/SB168, ASTM B443/SB443/B424/SB424B625/SB625 B575/SB575, JIS G4303, BS 1449, DN17441, G430 DetectionProcessing Packaging & ShippingCompany ProfileFAQQ1: Do you accept the trial order ?A1: Yes,if we have the exactly size in stock.we can delivery even 1 piece/meter .Q2: Can I have free sample before making orders?A2: Yes,we can supply free sample as requirement,but buyer needs to pay the freight charges ,the freight fee will return to buyer after making order.Q3: How do you control the quality ?A3: MTC and PMI will be sent before shipment,any 3rd party inspection if need .Q4: How about your delivery time ?A4: Generally delivery time is 15 working days .Q5: How can I quickly get the price list ?A5: Directly click "chat now" or send us email with detail specifications,you will get the official price list in 1 hour .
