Product Description ASTM A335 P91 P11 Seamless Alloy Steel Tube Available Stock A335/SA335 Grade P22 Alloy Steel Seamless Pipes are Carbon steel pipes with addition of chromium, molybdenum, and sometimes vanadium. Chromium, or chrome, improves high-temperature strength, increases oxidation resistance and raises the tensile, yield and hardness at room temperatures. Molybdenum increases the strength, elastic limit, resistance to wear, impact qualities and hardenability. It increases the resistance to softening, restrains grain growth and makes chromium steel less susceptible to embrittlement. Moly is also the most effective additive for increasing high temperature creep strength, or creep resistance, and it also enhances the corrosion resistance of steel and inhibits pitting. Grade P22 is used for high temperature service applications and is tolerant to variations in its microstructure.Widely used in Pharmaceutical equipmentChemical equipmentSea water equipmentHeat exchangersCondensersPulp and paper industryOff-shore oil drilling companiesPower generationPetrochemicalsGas processingSpecialty chemicalsSpecifications TypeSeamless StandardASME B 36.10M Material ASTM A335 Grade P22 Size Range 1/2 "-24" (DN15-600)Wall Thickness SCH20, SCH30, STD, SCH40, SCH60,SCH80,SCH100,SCH120, SCH140,SCH160, SCHXXS Length5.8m, 6m, 11.8m, 5-7m,6-9m or as on request.SurfaceAnti-rust oil, varnish on requestPackingfurnish bared, hex. bundles ,standard seaworthy.Marking Logo, standard , material, size, heat no.Quality guarantee100% UT passed mechanical testing including resistance test, chemical analysis, positive material classification, flattering test, micro and macro Test, pitting conflict test, flaring Test, inter granular decay testMill's Test CertificateEN10204 3.1 Chemical composition & mechanical propertiesCarbon - 0.05% - 0.15%Manganese - 0.30% - 0.60%Phosphorus, max - 0.025%Sulfur, max - 0.025%Silicon, max - 0.50%Chromium - 1.90% - 2.60Molybdenum - 0.87% - 1.13%Tensile strength, min, PSI, (MPa) - 60,000 (415)Yield Strength, min, (MPa) - 30,000 (205)Company ProfileFrom 1989 to now, Kingmetal Steel focus on manufacturing and distributing pipeline products including piping, fitting, flange, valve and fastener in stainless, carbon, alloy and duplex steel.
