FAQ
Q1: Dab tsi yog qhov txawv ntawm 310S thiab zoo tib yam 310 stainless hlau?
310S yog qhov hloov kho qis- carbon version ntawm 310 stainless hlau. Nws cov ntsiab lus carbon yog nruj me ntsis tswj hauv qab 0.08%, uas zoo inhibits chromium carbide nag lossis daus nyob rau hauv ntev - lub sij hawm siab - kub. Nws tsis txhob cuam tshuam kev cuam tshuam ntawm kev sib tsoo thiab vuam tawg, ua kom zoo dua siab dua - qhov kub thiab txias thiab kev pab cuam lub neej ntev, ua rau nws tsim nyog rau kev ua haujlwm tsis tu ncua siab - qhov kub thiab txias ua haujlwm tshaj li tus qauv 310 steel.
Q2: Cov txiaj ntsig ntawm softened & descaled kho yog dab tsi?
Cov tshuaj softened annealing kho tshem tawm cov kev ntxhov siab sab hauv uas tsim los ntawm kub dov, optimizes cov qauv nplej, thiab txhim kho cov phaj ductility, khoov kev ua tau zoo thiab weldability, txo cov txheej txheem tawg. Cov txheej txheem descaling tag nrho tshem tawm cov oxide txheej thiab impurities, ua kom lub tiaj tiaj thiab huv si, txhim kho kev ua haujlwm tom qab xws li txiav, vuam thiab pleev xim, thiab txhim kho kev tiv thaiv corrosion thiab zoo nkauj.
Q3: Dab tsi yog qhov siab tshaj plaws ua haujlwm kub ntawm 310S stainless hlau phaj?
Qhov kub dov 310S phaj no tuaj yeem tiv taus qhov kub thiab txias mus txog 1100℃nyob rau hauv ib txwm muaj cua sov cua sov, thiab tuav ruaj khov oxidation tsis kam thiab txhua yam khoom. Nws tuaj yeem hloov kho mus rau qhov sib txawv siab - qhov kub thiab txias ua haujlwm siab tshaj 1100 degree, uas yog qhov zoo tshaj rau 304, 316L thiab lwm cov pa roj carbon monoxide qib hauv siab -kub tsis kam.
Q4: Puas yog kho qhov loj me thiab qhov chaw kho mob puas muaj?
Yog lawm. Peb txhawb customized thickness, dav, ntev thiab txiav ua raws li cov neeg siv khoom kos duab. Dhau li ntawm tus qauv softened & descaled tiav, peb tseem tuaj yeem muab polishing, pickling, sandblasting thiab lwm yam kev kho deg kom tau raws li qhov sib txawv ntawm daim ntawv thov thiab kev ua tiav.
Q5: Cov ntawv pov thawj thiab cov ntawv xeem twg tuaj yeem muab tau?
Tag nrho cov khoom ua raws li ASTM A240 tus qauv. Peb tuaj yeem muab cov ntaub ntawv pov thawj ntawm cov khoom siv hauv Hoobkas (MTR), cov ntaub ntawv txheeb xyuas tshuaj lom neeg, daim ntawv pov thawj kev ntsuas kev ua haujlwm, thiab thib peb -cov ntaub ntawv tshuaj xyuas tog (SGS, BV, thiab lwm yam) los txhawb cov neeg siv khoom pov thawj zoo thiab qhov kev lees paub.
Q6: Lub sijhawm xa khoom thiab ntim khoom yog dab tsi?
Cov pa ntau thiab tsawg yog nyob rau hauv Tshuag nrog ceev ceev. Customized sizes siv sijhawm 3-7 hnub ua haujlwm. Txheem export ntim txais cov ntawv tsis muaj dej + yas zaj duab xis + ntoo pallet / steel ncej packing los tiv thaiv xeb, deformation thiab kev puas tsuaj thaum lub sij hawm ntev hiav txwv thiab av thauj mus los, ua tau raws li thoob ntiaj teb export ntim cov qauv.
Q7: 310S stainless hlau phaj puas tuaj yeem welded thiab ua tiav?
kiag li. Tom qab softened annealing kev kho mob, lub phaj muaj zoo heev processability. Nws txhawb cov txheej txheem vuam zoo xws li argon arc vuam thiab hluav taws xob vuam nrog cov nyhuv vuam ruaj khov thiab tsis muaj kev tshaj tawm - vuam tsis ua haujlwm. Nws tuaj yeem raug txiav dawb, khoov, xuas nrig thiab machined rau theem nrab molding.
