Feem ntau, VJ Piping yog ua los ntawm stainless hlau xws li 304, 304L, 316 thiab 316Letc.Ntawm no peb yuav qhia luv luv txog cov yam ntxwv ntawm ntau yam khoom siv stainless hlau.

SIB 304

304 stainless hlau yeeb nkab yog tsim nyob rau hauv raws li American ASTM tus qauv ntawm ib hom ntawm stainless hlau.

304 stainless hlau yeeb nkab yog sib npaug rau peb 0Cr19Ni9 (OCr18Ni9) stainless hlau yeeb nkab.

304 stainless hlau raj li stainless hlau yog dav siv nyob rau hauv cov khoom noj khoom haus, khoom siv tshuaj, thiab atomic zog kev lag luam.

304 stainless hlau yeeb nkab yog universal stainless hlau yeeb nkab, nws yog dav siv nyob rau hauv zus tau tej cov kev ua tau zoo (corrosion resistance thiab formability) khoom thiab qhov chaw.

304 stainless hlau yeeb nkab yog feem ntau siv stainless hlau, kub resistant hlau.Siv rau hauv cov khoom siv khoom noj khoom haus, khoom siv tshuaj lom neeg, nuclear zog, thiab lwm yam.

304 stainless hlau raj tshuaj muaj pes tsawg leeg specifications C, Si, Mn, P, S, Cr, Ni, (Nickel), Mo.

Stainless hlau 304 thiab 304L Kev Ua Haujlwm Sib Txawv

304L yog ntau corrosion resistant, 304L muaj tsawg carbon, 304 yog ib tug universal stainless hlau, thiab nws yog dav siv nyob rau hauv zus tau tej cov khoom thiab qhov chaw uas yuav tsum tau muaj kev kawm zoo (corrosion kuj thiab formability).304L yog qhov sib txawv ntawm 304 stainless hlau nrog cov ntsiab lus qis dua thiab siv rau kev siv vuam.Cov ntsiab lus qis dua txo qis carbides nag lossis daus nyob rau hauv thaj chaw tshav kub uas nyob ze ntawm qhov vuam, uas tuaj yeem ua rau muaj kev cuam tshuam ntawm intergranular corrosion (welding yaig) hauv cov hlau tsis muaj steel hauv qee qhov chaw.

304 yog dav siv, nrog zoo corrosion kuj, tshav kub tsis kam, kub tsis tshua muaj zog thiab txhua yam khoom;Zoo thermal ua, xws li stamping thiab dabtsi yog khoov, tsis muaj kev kho cua sov hardening tshwm sim (tsis muaj hlau nplaum, siv kub -196 ℃ -800 ℃).

304L muaj kev tiv thaiv zoo heev rau cov qoob loo ciam teb tom qab vuam lossis kev ntxhov siab: nws tuaj yeem tswj tau zoo corrosion txawm tias tsis muaj kev kho cua sov, kev ua haujlwm kub -196 ℃ -800 ℃.

SIB 316

316 stainless hlau kuj muaj cov tshuaj chloride yaig zoo, yog li nws feem ntau siv nyob rau hauv Marine ib puag ncig.

Corrosion resistant stainless hlau raj Hoobkas

Corrosion kuj yog zoo dua li 304 stainless hlau, nyob rau hauv cov txheej txheem ntawm cov ntaub so ntswg thiab ntawv muaj corrosion kuj zoo.

Thiab 316 stainless hlau kuj yog resistant rau Marine thiab aggressive industrial atmospheres.Thaum tshav kub kub tsis kam nyob rau hauv 1600 degrees hauv qab qhov kev siv tsis tu ncua thiab nyob rau hauv 1700 degrees hauv qab no siv tas mus li, 316 stainless hlau muaj oxidation zoo.

Nyob rau hauv qhov ntau ntawm 800-1575 degrees, nws yog qhov zoo tshaj plaws kom tsis txhob siv 316 stainless hlau txuas ntxiv, tab sis nyob rau hauv qhov kub thiab txias sab nraum qhov kev siv tsis tu ncua ntawm 316 stainless hlau, cov hlau tsis muaj hlau muaj qhov kub zoo.

Carbide nag lossis daus tsis kam ntawm 316 stainless hlau yog zoo dua li ntawm 316 stainless hlau thiab tuaj yeem siv rau hauv qhov kub thiab txias.

316 stainless hlau muaj kev ua haujlwm zoo vuam.Yuav tau welded siv tag nrho cov txheej txheem vuam txoj kev.Vuam tuaj yeem siv tau raws li kev siv 316Cb, 316L lossis 309CB stainless hlau muab tub lim lossis electrode vuam.Yuav kom tau txais qhov zoo tshaj plaws corrosion kuj, welded seem ntawm 316 stainless hlau yuav tsum tau annealed tom qab vuam.Post weld annealing tsis tas yuav tsum yog 316L stainless hlau siv.

Kev siv cov khoom siv: cov khoom siv pulp thiab ntawv cov khoom siv hluav taws xob sib hloov, cov khoom siv dyeing, cov cuab yeej tsim cov yeeb yaj kiab, cov kav dej, thiab cov khoom siv rau sab nrauv ntawm cov tsev hauv nroog hauv cov ntug dej hiav txwv.

Antibacterial Stainless hlau

Nrog rau txoj kev loj hlob ntawm kev lag luam, stainless hlau nyob rau hauv kev lag luam khoom noj khoom haus, catering kev pab cuam thiab daim ntawv thov ntawm tsev neeg lub neej yog ntau thiab ntau dav, nws yog cia siab hais tias nyob rau hauv tas li ntawd mus stainless hlau tsev cov tais diav thiab tableware, kaj thiab huv si raws li tshiab nta, tab sis kuj muaj. qhov zoo tshaj plaws mildew, antibacterial, ua kom tsis muaj menyuam.

Raws li peb txhua tus paub, qee cov hlau, xws li nyiaj, tooj liab, bismuth thiab lwm yam muaj cov kab mob tua kab mob, cov kab mob bactericidal, lub npe hu ua antibacterial stainless hlau, yog nyob rau hauv stainless hlau los ntxiv cov khoom tsim nyog nrog cov tshuaj tua kab mob (xws li tooj liab. , silver), zus tau tej cov hlau tom qab antibacterial tshav kub kho, nrog ruaj khov kev ua tau zoo thiab zoo antibacterial kev ua tau zoo.

Tooj liab yog lub hauv paus tseem ceeb ntawm cov kab mob tua kab mob, ntau npaum li cas ntxiv yuav tsum tsis tsuas yog xav txog cov cuab yeej tiv thaiv kab mob, tab sis kuj ua kom cov khoom zoo thiab ruaj khov ntawm cov hlau.Qhov zoo tshaj plaws ntawm tooj liab sib txawv nrog steel hom.Tshuaj muaj pes tsawg leeg ntawm antibacterial stainless hlau tsim los ntawm Nyiv Nissin Steel yog qhia nyob rau hauv Table 10. 1.5% tooj liab yog ntxiv rau ferritic steel, 3% rau martensitic steel thiab 3.8% rau austenitic hlau.
