SUS304 (SUS txhais tau tias stainless hlau rau hlau) stainless hlau austenite feem ntau hu ua SS304 los yog AISI 304 hauv Japanese. Qhov sib txawv tseem ceeb ntawm ob cov ntaub ntawv tsis yog cov khoom siv lub cev lossis cov yam ntxwv, tab sis txoj kev uas lawv tau hais hauv Tebchaws Meskas thiab Nyij Pooj.
Txawm li cas los xij, muaj qhov sib txawv ntawm ob lub hlau. Hauv ib qho piv txwv, SS304 cov qauv tau txais los ntawm Asmeskas cov peev txheej thiab SUS304 cov qauv tau los ntawm Nyij Pooj tau raug xa mus rau chav kuaj sim.
SUS304 (JIS tus qauv) yog ib qho ntawm feem ntau siv cov qauv ntawm stainless hlau. Nws yog tsim los ntawm 18% Cr (chromium) thiab 8% Ni (nickel). Nws tseem tuaj yeem tuav nws lub zog thiab kub ua haujlwm ntawm qhov kub thiab txias. Nws kuj muaj qhov zoo weldability, mechanical zog, txias workability thiab corrosion kuj ntawm chav tsev kub. SS304 (ANSI 304) yog feem ntau siv stainless hlau thaum tsim lwm yam stainless hlau cov ntaub ntawv, thiab feem ntau yog yuav nyob rau hauv txias los yog annealing tej yam kev mob. Zoo ib yam li SUS304, SS304 kuj muaj 18% Cr thiab 8% Ni, yog li nws hu ua 18/8. SS304 muaj zoo weldability, tshav kub tsis kam, corrosion kuj, tsis tshua muaj kub lub zog, workability, mechanical zog, kub kho tsis hardened, dabtsi yog khoov, stamping isothermal workability yog zoo. SS304 yog dav siv nyob rau hauv ntau lub lag luam, nrog rau cov khoom noj, kev kho mob thiab kho kom zoo nkauj ua hauj lwm. Tshuaj muaj pes tsawg leeg ntawm SUS304 thiab SS304

Corrosion tsis kam ntawm 304 stainless hlau Raws li peb txhua tus paub, 304 stainless hlau ua tau zoo nyob rau hauv ntau qhov chaw ntawm huab cua thiab corrosive media. Txawm li cas los xij, nyob rau hauv ib puag ncig sov chloride, thaum qhov kub siab tshaj 60 ° C, nws yooj yim rau pitting corrosion, crevice corrosion thiab stress corrosion. Ntawm qhov kub thiab txias, nws kuj tseem pom tau tias muaj peev xwm tiv taus cov dej haus uas muaj txog li 200 mg / l chloride.Lub cev yam ntxwv ntawm SUS304 thiab SS304
Ob qho khoom siv tau zoo heev hauv lub cev thiab tshuaj lom neeg, yog li nws yooj yim hais tias lawv yog cov khoom siv tib yam. Ib yam li ntawd, qhov sib txawv tseem ceeb ntawm ob lub teb chaws yog kev tsim qauv ntawm Tebchaws Meskas thiab Nyij Pooj. Qhov no txhais tau hais tias tshwj tsis yog cov kev cai tshwj xeeb lossis cov kev cai tshwj xeeb tau teev tseg los ntawm lub tebchaws lossis cov neeg siv khoom, txhua yam khoom siv tuaj yeem hloov pauv.
