ASTM A789 UNS S31803 Duplex 2205 Tube

 

Core Standards thiab Basic Specifications

Ua raws li tus qauv: Nws nruj me ntsis ua raws li ASTM A789 / ASME SA - 789 tus qauv, uas yog qhov kev tso cai tshwj xeeb rau cov raj duplex stainless hlau tsim los ntawm American Society for Testing and Materials. Nws kuj ua raws li cov qauv sib xws xws li ASTM A790 thiab ASTM A928.

Dimensional Range: Cov tubing muaj nyob rau hauv ob qho tib si seamless thiab welded hom. Lub seamless version feem ntau npog ib txoj kab uas hla sab nraud ntawm 6.0 - 630 hli, nrog phab ntsa thickness ntawm 0.6mm mus rau 6.0mm, thiab ntev feem ntau yog li ntawm 1 - 6 meters, uas tuaj yeem kho raws li xav tau. Cov kev kho mob feem ntau suav nrog beveled xaus thiab qhov kawg, thiab cov khoom tiav yog ntau haiv neeg, xws li annealed & pickled, ci annealed, thiab polished nto.

Tshuaj muaj pes tsawg leegCov tshuaj lom neeg muaj pes tsawg leeg ntawm lub raj no yog qhov sib luag kom ntseeg tau tias nws ob - theem qauv thiab kev ua tau zoo. Cov khoom tshwj xeeb (qhov siab tshaj plaws lossis ntau qhov feem pua) yog raws li hauv qab no: Chromium ({2}}%), Nickel (4.50 - 6.50%), Molybdenum (2.50 - 3.50%), Nitrogen ({5}}%), Carbon (tsawg dua lossis sib npaug li 0.030%), Manganese (Less dua lossis sib npaug li 2.00%), Silicon tshaj los yog sib npaug li 1.00%), Phosphorus (Less tshaj los yog sib npaug rau 0.030%), Sulfur (Less tshaj los yog sib npaug rau 0.020%), thiab hlau raws li qhov sib npaug. Qhov sib ntxiv ntawm nitrogen tsis tsuas yog txhim kho nws cov corrosion kuj, tab sis kuj txhim kho nws cov weldability.
