Dab tsi yog cov txiaj ntsig ntawm cov kav hlau stainless?
Stainless hlau yeeb nkab cov txiaj ntsig
1, lub neej ua haujlwm ntev
Cov kav hlau stainless muaj lub neej ua haujlwm ntev tshaj plaws. Los ntawm kev soj ntsuam ntawm daim ntawv thov txheej txheem ntawm stainless hlau kav hauv tsev thiab txawv teb chaws, daim ntawv thov lub neej ntawm stainless hlau kav mus txog 100 xyoo, tsawg kawg yog 70 xyoo, uas yog ntev li ntev raws li lub neej kev pab cuam ntawm lub tsev.
2, muaj zog corrosion kuj
Ib qho ntawm qhov zoo tshaj plaws ntawm cov kav hlau stainless yog nws cov kev tiv thaiv corrosion zoo heev, vim tias cov hlau tsis muaj zog tuaj yeem cuam tshuam nrog oxidants, yog li nws yog qhov zoo dua me ntsis ntawm ntau yam kav dej.
3, zoo tshav kub tsis kam thiab rwb thaiv tsev kev ua tau zoo
Lub thermal conductivity ntawm stainless hlau yeeb nkab yog 1/25 ntawm cov yeeb nkab tooj liab thiab 1/4 ntawm cov yeeb nkab steel, uas yog qhov tsim nyog rau kev thauj mus los ntawm cov dej kub. Feem ntau siv stainless hlau hauv kev lag luam dej yog 316 thiab 304 stainless hlau, uas tuaj yeem ua tau raws li feem ntau ntawm kev kho dej thiab kev thauj mus los.
4, siab compressive zog
Lub zog tensile ntawm 304 stainless hlau yeeb nkab yog 2 npaug ntawm cov yeeb nkab steel, thiab 8 mus rau 10 npaug ntawm cov yeeb nkab yas. Lub zog compressive ntawm cov khoom txiav txim siab seb cov yeeb nkab dej puas muaj zog thiab sib tsoo-resistant, nyab xeeb thiab ruaj khov. Kev nyab xeeb thiab kev ruaj ntseg yog tus qauv tseem ceeb tshaj plaws rau kev tsim cov dej hauv tsev, nyob rau hauv cov ntaub ntawv ntawm kev quab yuam sab nraud lossis lwm yam, qhov tshwm sim ntawm cov dej tsis muaj dej tsis zoo yog qhov tsawg heev.
304 yog ntau yam stainless hlau yeeb nkab, uas yog dav siv nyob rau hauv zus tau tej cov cuab yeej thiab qhov chaw uas yuav tsum tau muaj zoo comprehensive zog (corrosion kuj thiab formability). 304 stainless hlau yeeb nkab yog qib stainless hlau ua raws li American ASTM tus qauv, uas yog sib npaug rau Tuam Tshoj tus 0Cr19Ni9 (0Cr18Ni9) stainless hlau. 304 muaj 19% chromium, 9% npib tsib xee, yog cov khoom siv dav 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.
