Feem ntau, VJ Piping yog ua los ntawm cov hlau tsis xeb xws li 304, 304L, 316 thiab 316Letc. Ntawm no peb yuav qhia luv luv txog cov yam ntxwv ntawm ntau yam khoom siv hlau tsis xeb.
SS304
304 stainless hlau yeeb nkab yog tsim tawm raws li American ASTM tus qauv ntawm ib hom stainless hlau.
304 cov yeeb nkab stainless hlau yog sib npaug rau peb cov yeeb nkab stainless hlau 0Cr19Ni9 (OCr18Ni9).
304 stainless hlau raj ua stainless hlau yog feem ntau siv rau hauv cov khoom siv khoom noj khoom haus, cov khoom siv tshuaj lom neeg dav dav, thiab kev lag luam atomic energy.
304 stainless hlau yeeb nkab yog ib qho yeeb nkab stainless hlau thoob ntiaj teb, nws yog dav siv rau hauv kev tsim cov khoom siv thiab qhov chaw ua tau zoo (kev tiv taus corrosion thiab formability).
304 stainless hlau yeeb nkab yog cov hlau stainless hlau uas tiv taus cua sov feem ntau siv. Siv rau hauv cov khoom siv tsim khoom noj, cov khoom siv tshuaj dav dav, lub zog nuclear, thiab lwm yam.
304 stainless hlau raj tshuaj lom neeg cov lus qhia C, Si, Mn, P, S, Cr, Ni, (Nickel), Mo.
Stainless Steel 304 thiab 304L Kev Ua Tau Zoo Sib Txawv
304L yog cov hlau uas tiv taus xeb ntau dua, 304L muaj cov pa roj carbon tsawg dua, 304 yog cov hlau tsis xeb uas siv tau rau txhua yam, thiab nws siv dav hauv kev tsim cov khoom siv thiab cov khoom uas xav tau kev ua haujlwm zoo (kev tiv taus xeb thiab kev ua kom zoo). 304L yog ib qho sib txawv ntawm 304 stainless hlau nrog cov pa roj carbon tsawg dua thiab siv rau kev siv vuam. Cov pa roj carbon tsawg dua txo cov carbides nag hauv thaj chaw kub ze ntawm qhov vuam, uas tuaj yeem ua rau muaj kev xeb intergranular (kev vuam puas tsuaj) hauv cov hlau tsis xeb hauv qee qhov chaw.
304 yog siv dav, nrog kev tiv thaiv corrosion zoo, tiv thaiv kub, lub zog kub qis thiab cov khoom siv kho tshuab; Kev ua haujlwm thermal zoo, xws li stamping thiab khoov, tsis muaj kev kho cua sov hardening phenomenon (tsis muaj magnetic, siv qhov kub -196 ℃ -800 ℃).
304L muaj kev tiv thaiv zoo heev rau kev xeb ntawm cov ciam teb tom qab vuam lossis kev ntxhov siab: nws tuaj yeem tswj tau qhov kev tiv thaiv xeb zoo txawm tias tsis muaj kev kho cua sov, kev ua haujlwm kub -196 ℃ -800 ℃.
SS316
316 stainless hlau kuj muaj cov khoom zoo chloride erosion, yog li nws feem ntau siv rau hauv Marine ib puag ncig.
Hoobkas ua cov yeeb nkab tsis xeb uas tiv taus xeb
Kev tiv thaiv corrosion zoo dua li 304 stainless hlau, hauv cov txheej txheem ntau lawm ntawm pulp thiab ntawv muaj kev tiv thaiv corrosion zoo.
Thiab 316 stainless hlau kuj tiv taus Marine thiab kev lag luam hnyav. Kev tiv taus cua sov hauv 1600 degrees qis dua kev siv tsis tu ncua thiab hauv 1700 degrees qis dua kev siv tas mus li, 316 stainless hlau muaj kev tiv thaiv oxidation zoo.
Nyob rau hauv qhov ntau ntawm 800-1575 degrees, nws yog qhov zoo tshaj plaws kom tsis txhob siv 316 stainless hlau tas li, tab sis nyob rau hauv qhov kub thiab txias sab nraum kev siv tas mus li ntawm 316 stainless hlau, cov hlau stainless hlau muaj kev tiv thaiv cua sov zoo.
Qhov tsis kam ntawm carbide nag lossis daus ntawm 316 stainless hlau zoo dua li ntawm 316 stainless hlau thiab tuaj yeem siv rau hauv qhov kub siab tshaj.
316 stainless hlau muaj kev ua haujlwm vuam zoo. Yuav siv tau txhua txoj kev vuam txheem. Kev vuam siv tau raws li kev siv 316Cb, 316L lossis 309CB stainless hlau filler rod lossis electrode welding. Yuav kom tau txais qhov zoo tshaj plaws corrosion tsis kam, qhov welded seem ntawm 316 stainless hlau yuav tsum tau annealed tom qab welding. Post weld annealing tsis tas yuav yog 316L stainless hlau siv.
Cov kev siv ib txwm muaj: cov khoom siv hloov pauv cua sov ntawm cov khoom siv pulp thiab ntawv, cov khoom siv zas xim, cov khoom siv tsim zaj duab xis, cov kav dej, thiab cov ntaub ntawv rau sab nraud ntawm cov tsev hauv nroog hauv thaj chaw ntug dej hiav txwv.
Cov Hlau Stainless Hlau Tiv Thaiv Kab Mob
Nrog rau kev txhim kho ntawm kev lag luam, cov hlau tsis xeb hauv kev lag luam zaub mov, kev pabcuam catering thiab kev siv hauv tsev neeg tau dav dua thiab ntau dua, nws vam tias ntxiv rau cov khoom siv hauv tsev thiab cov tais diav tsis xeb, nws kuj tseem ci thiab huv si, tab sis kuj muaj cov pwm zoo tshaj plaws, cov kab mob tua kab mob, thiab cov haujlwm tua kab mob.
Raws li peb txhua tus paub, qee cov hlau, xws li nyiaj, tooj liab, bismuth thiab lwm yam muaj cov nyhuv antibacterial, bactericidal, qhov thiaj li hu ua antibacterial stainless hlau, yog nyob rau hauv stainless hlau ntxiv cov khoom kom raug nrog cov nyhuv antibacterial (xws li tooj liab, nyiaj), tsim cov hlau tom qab antibacterial cua sov kho, nrog kev ua haujlwm ruaj khov thiab kev ua haujlwm zoo antibacterial.
Tooj liab yog qhov tseem ceeb ntawm cov tshuaj tua kab mob, ntau npaum li cas ntxiv yuav tsum tsis txhob tsuas yog xav txog cov khoom tua kab mob xwb, tab sis kuj tseem xyuas kom meej tias cov khoom ua tiav zoo thiab ruaj khov ntawm cov hlau. Qhov ntau ntawm tooj liab zoo tshaj plaws sib txawv nrog cov hom hlau. Cov tshuaj lom neeg ntawm cov hlau tsis xeb tiv thaiv kab mob tsim los ntawm Japanese Nissin Steel tau qhia hauv Rooj 10. 1.5% tooj liab yog ntxiv rau cov hlau ferritic, 3% rau cov hlau martensitic thiab 3.8% rau cov hlau austenitic.
