Taw qhia
Cov ntawv hlau stainless yog cov khoom siv nrov tshaj plaws uas tau siv rau ntau xyoo tam sim no. Nws yog tsim los ntawm ntau qib ntawm stainless hlau thiab muaj cov khoom sib txawv thiab cov yam ntxwv. Cov qib ntawm cov ntawv hlau stainless yog categorized los ntawm American Iron and Steel Institute (AISI) raws li hauv qab no: 2XX Series, 3XX Series, 4XX Series, thiab 5XX Series. Hauv tsab xov xwm no, peb yuav tham txog cov ntsiab lus ntawm cov ntawv hlau stainless, lawv cov khoom, thiab lawv siv.
2 XX Series
2XX series ntawm stainless hlau los xij yog tsim los ntawm ob hom stainless hlau: austenitic thiab ferritic. Qib feem ntau ntawm austenitic stainless hlau los xij yog qib 201. Nws yog ib qho tsis tshua muaj nickel stainless hlau uas muaj cov ntsiab lus siab manganese thiab tsis tshua kim dua lwm hom stainless hlau. Nws yog feem ntau siv hauv cov khoom siv hauv chav ua noj, cov khoom siv ua zaub mov, thiab cov tais diav.
Lwm qib ntawm austenitic stainless hlau nplooj ntawv hauv 2XX series yog qib 202. Qib no muaj chromium, npib tsib xee, thiab manganese thiab muaj zog dua li qib 201. Nws yog feem ntau siv rau hauv kev siv tsheb, khoom siv hauv tsev, thiab hose clamps.
Ob qib nrov tshaj plaws ntawm ferritic stainless hlau ntawv hauv 2XX series yog qib 409 thiab 430. Qib 409 yog siv rau hauv cov tshuab muffler thiab cov tshuab tso pa hauv tsheb, thaum qib 430 yog siv rau hauv cov khoom siv thiab cov khoom siv hauv tsheb.
3XX Series
3XX series ntawm stainless hlau los xij yog cov qib feem ntau siv stainless hlau. Nws yog austenitic stainless hlau uas muaj nickel, chromium, thiab molybdenum. Cov qib nrov tshaj plaws ntawm 3XX series yog qib 304 thiab 316.
Qib 304 yog qib feem ntau siv stainless hlau hauv ntiaj teb. Nws yog siv nyob rau hauv ntau yam kev siv, nrog rau cov khoom noj khoom haus, cov khoom siv tshuaj, thiab cov khoom siv kho mob. Qib 316 feem ntau yog siv rau hauv kev siv dej hiav txwv, khoom siv tshuaj lom neeg, thiab tshuaj.
4XX Series
4XX series ntawm stainless hlau los xij yog ib pawg ntawm ferritic thiab martensitic stainless hlau uas muaj 11% mus rau 30% chromium. Qee cov qib nrov hauv cov koob no yog qib 405, 409, thiab 434. Qib 405 yog siv rau hauv cov khoom siv hluav taws xob thiab cov tshuab tso pa tawm, qib 409 yog siv rau hauv cov mufflers thiab cov pa tawm, thiab qib 434 yog siv rau hauv cov khoom siv tsheb.
5 XX Series
5XX series ntawm stainless hlau los xij yog qib nrov tshaj plaws ntawm nag lossis daus-hardening stainless hlau. Lawv muaj npib tsib xee, chromium, tooj liab, thiab lwm yam khoom uas muab lub zog thiab corrosion kuj. Cov qib nrov tshaj plaws hauv cov koob no yog qib 17-4 PH, uas yog siv hauv aerospace, tshuaj ua haujlwm, thiab cov khoom siv kho mob.
Xaus
Stainless hlau ntawv tuaj nyob rau hauv ntau qib thiab siv nyob rau hauv ntau yam kev siv. Cov qib ntawm cov ntawv hlau stainless yog categorized los ntawm American Iron thiab Steel Institute (AISI) raws li 2XX Series, 3XX Series, 4XX Series, thiab 5XX Series. Txhua qib nws muaj nws cov khoom thiab cov yam ntxwv uas ua rau nws haum rau cov ntawv thov tshwj xeeb. Yog tias koj tab tom npaj siv cov ntawv hlau stainless hauv koj qhov project tom ntej, nws yog ib qho tseem ceeb uas yuav tau xaiv cov qib zoo ntawm stainless hlau uas yuav ua tau raws li koj cov kev xav tau.
