Muaj zog npaum li cas yog 304 stainless hlau?

Stainless hlau yog ib hom hlau alloy dav siv nyob rau hauv ntau yam kev lag luam thiab pej xeem kev lag luam, vim nws cov corrosion kuj, zoo nkauj tsos, ua tau yooj yim thiab lwm yam ntxwv. Ntawm ntau hom stainless hlau, 304 stainless hlau tau dhau los ua ib qho ntawm ntau hom stainless hlau nyob rau hauv kev ua lag luam vim nws cov kev ua tau zoo heev thiab ntau yam kev siv. Yog li, muaj zog npaum li cas yog 304 stainless hlau? Nyob rau hauv daim ntawv no, lub zog ntawm 304 stainless hlau yog luv luv soj ntsuam los ntawm qhov pom ntawm cov khoom siv mechanics.

Muaj pes tsawg leeg thiab cov yam ntxwv ntawm 304 stainless hlau

304 stainless hlau yog ib hom austenitic stainless hlau, nws cov khoom tseem ceeb muaj xws li hlau, chromium, npib tsib xee thiab lwm yam khoom. Ntawm lawv, cov ntsiab lus ntawm chromium feem ntau yog 18% -20%, thiab cov ntsiab lus ntawm nickel yog 8% -10.5%. Qhov sib ntxiv ntawm cov ntsiab lus no ua rau 304 stainless hlau muaj kev tiv thaiv corrosion zoo thiab ua haujlwm, tshwj xeeb tshaj yog nyob rau hauv chav tsev kub, nws cov corrosion kuj zoo heev.

Lub zog Performance index ntawm 304 stainless hlau

Lub zog tensile: Lub zog tensile ntawm 304 stainless hlau feem ntau yog nruab nrab ntawm 520MPa thiab 700MPa, nyob ntawm seb lub xeev kho cua sov thiab cov txheej txheem ntawm cov khoom siv. Lub zog tensile yog ib qho kev ntsuas ntawm lub peev xwm ntawm cov khoom siv los tiv thaiv kev puas tsuaj thaum lub sij hawm tensile txheej txheem, thiab yog ib qho tseem ceeb parameter los ntsuas lub zog ntawm cov khoom.
Yield zog: Lub zog tawm los yog lub ntsiab lus tseem ceeb uas cov khoom pib ua rau cov yas deformation nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam. Lub zog tawm los ntawm 304 stainless hlau feem ntau yog nruab nrab ntawm 205MPa thiab 310MPa.
Elongation: Elongation yog qhov siab tshaj plaws ntawm deformation uas cov khoom tuaj yeem tiv taus ua ntej tensile tawg, xav txog cov yas deformation muaj peev xwm ntawm cov khoom. Lub elongation ntawm 304 stainless hlau yog feem ntau ntawm 40% thiab 60%.

Lub zog ntawm 304 stainless hlau daim ntawv thov

Vim tias 304 stainless hlau muaj kev tiv thaiv corrosion zoo heev thiab nruab nrab lub zog, nws yog dav siv hauv kev tsim kho, tshuaj, khoom noj, kev kho mob thiab lwm yam. Nyob rau hauv kev tsim kho, 304 stainless hlau feem ntau yog siv los ua lub qhov rooj thiab qhov rais, railings, hniav panels, thiab lwm yam. Nyob rau hauv cov tshuaj thiab zaub mov teb, nws yog siv los ua cia tank, pipelines, khoom siv, thiab lwm yam, vim nws corrosion kuj; Hauv kev kho mob, 304 stainless hlau yog siv los ua cov cuab yeej phais thiab cov cuab yeej kho hniav vim nws cov biocompatibility thiab corrosion kuj.

Cov ntsiab lus

304 stainless hlau yog cov khoom siv stainless hlau nrog lub zog nruab nrab, zoo corrosion kuj thiab ua haujlwm. Nws lub zog tensile, yield zog thiab elongation thiab lwm yam ntsuas tau zoo heev, yog li nws muaj ntau yam kev siv hauv ntau qhov chaw. Txawm li cas los xij, nws yuav tsum raug sau tseg tias thaj chaw sib txawv muaj qhov sib txawv ntawm cov khoom siv, yog li thaum xaiv 304 stainless hlau ua cov khoom siv, cov khoom tsim nyog xaiv thiab tsim yuav tsum tau ua raws li kev siv tshwj xeeb thiab cov kev cai.
