The alloy resists oxidation up to 1900°F (1038°C) under non-cyclic conditions. Frequent thermal cyclingreduces oxidation resistance to approximately 1850°F (1010°C).Because of its high chromium and low nickel content, Alloy 309 can be utilized in sulfur containing atmospheres up to1832°F (1000°C). The alloy is not recommended for use in highly carburizing atmospheres since it exhibits only moderateresistance to carbon absorption. Alloy 309 can be utilized in slightly oxidizing, nitriding, cementing and thermal cyclingapplications, albeit, the maximum service temperature must be reduced.When heated between 1202 - 1742°F (650 - 950°C) the alloy is subject to sigma phase precipitation. A solution annealingtreatment at 2012 - 2102°F (1100 - 1150°C) will restore a degree of toughness.309S (UNS S30908) is the low carbon version of the alloy. It is utilized for ease of fabrication. 309H (UNS S30909) is ahigh carbon modification developed for enhanced creep resistance. It most instances the grain size and carbon content ofthe plate can meet both the 309S and 309H requirements.Alloy 309 can be easily welded and processed by standard shop fabrication practices.2: Chemical CompositionTianjin Zhongyantiancheng Steel Co.,LtdCommodityStainless Steel Pipe/Welded Steel Tube/Seamless Steel PipeMaterial309SStandardGBJISASTM/ASMEDIN06Cr23Ni13SUS309S309S1.4833Chemical CompositionCMnPS<=0.08<=2.00<=0.045<=0.03SiCrNNi<=0.0322--24No12--15Outside Diameter4mm--720mmThickness0.5mm-68mmLengthProduce as customers' requestSurfaceBlack/BrightmanufactureHot Rolled/Cold DrawnPackingPacked in bundles with standard export sea-worthy packageDelivery TimeWithin 15 working days, according to customers' quantitiesQualityHigh Quality.SGS inspection is accepted if neededPlace of OriginTianjinProductivity500 MT/MonthPaymentT/T,L/CMOQ1 MTApplicationFoodstuff, Gas, metallurgy, biology, electron, chemical etc.NoteWe can also do other materials3: Stainless Steel Seamless Pipe Or Welded Pipe Process4: Stainless Steel Seamless Or Welded Pipe Package5: Company Introduction
