Khoom Description
1.4449 Weled Stainless Hlau Tube
1.4449 stainless hlau yog austenitic chromium-nickel hlau alloy nrog cov khoom sib xyaw siab dua li 316 hom kev tshuaj xyuas, nrog 3-4% molybdenum. Qhov siab dua ntawm molybdenum zoo heev txhim kho Hom 317 tsis kam rau pitting thiab crevice corrosion. Nrog rau kev tiv thaiv corrosion, Hom 317 kuj muaj lub zog tensile thiab creep lub zog ntawm qhov kub siab.

1.4449 Weled Stainless Hlau Tube
Hom 317 stainless hlau muaj peev xwm sawv tawm tsam kev tawm tsam los ntawm sulphurous, acetic, formic, citric thiab tartaric acids thiab tiv thaiv pitting vim phosphorous acid, chlorides, bromides thiab iodides Qhov no ua rau nws xaiv zoo tshaj plaws ntawm qib steel hauv cov haujlwm thiab cov xwm txheej uas ib puag ncig yuav tsum tau stainless hlau nrog corrosion kuj ntau dua los ntawm kev sib cuam tshuam tshuaj, muaj kuab paug los yog ntsev ntau dhau.
Alloy 317L (UNS S31703) yog molybdenum-cov kabmob austenitic stainless hlau uas muaj zog tiv thaiv tshuaj tua kab mob zoo li piv rau cov pa chromium-nickel austenitic stainless hlau xws li Alloy 304. Tsis tas li ntawd, Alloy 317L muaj ntau dua creep, kev nyuaj siab-rau- rupture, thiab tensile lub zog ntawm qhov kub siab tshaj li cov pa stainless hlau. Nws yog cov pa roj carbon tsawg lossis "L" qib uas muab kev tiv thaiv rau rhiab heev thaum vuam thiab lwm yam txheej txheem thermal.
