304 stainless hlau thiab 304L stainless hlau yog ob hom stainless hlau cov ntaub ntawv uas muaj qee qhov sib txawv me me hauv cov tshuaj muaj pes tsawg leeg uas yuav cuam tshuam rau lawv cov khoom siv kho tshuab, suav nrog304L stainless hlau tensile zog. Txawm li cas los xij, cov nyhuv no feem ntau yog me me thiab tej zaum yuav tsis yog qhov tseem ceeb rau feem ntau daim ntawv thov.
304 stainless hlau yog ib hom stainless hlau uas zoo heev corrosion kuj thiab txhua yam khoom. Nws muaj 18% chromium thiab 8% npib tsib xee, nrog rau qee cov pa roj carbon, manganese thiab lwm yam khoom. 304L stainless hlau yog ib qho qis-carbon version ntawm 304 stainless hlau. Nws cov ntsiab lus qis dua cov pa roj carbon monoxide pab txo qis kev nyiam carbonize thaum vuam.
Nyob rau hauv cov nqe lus ntawm tensile zog, feem ntau,lub zog tensile ntawm 304 stainless hlautej zaum yuav siab dua me ntsis ntawm 304L stainless hlau vim tias cov ntsiab lus carbon ntau dua hauv 304 stainless hlau. Txawm li cas los xij, qhov sib txawv ntawm lub zog tensile yuav tsis pom zoo heev thiab tseem cuam tshuam los ntawm lwm yam xws li kev kho cua sov thiab kev ua haujlwm.
Thaum xaiv 304 stainless hlau thiab 304L stainless hlau, qhov kev xaiv yuav tsum yog raws li cov kev xav tau tshwj xeeb thiab kev ua haujlwm. Yog tias tsis muaj kev txwv tshwj xeeb rau qhov sib txawv me me hauv304 stainless hlau tensile zog, ob leeg tuaj yeem txiav txim siab. Xav txog yam xws li cov khoom siv kho tshuab, kev tiv thaiv corrosion, thiab weldability los xaiv cov khoom zoo tshaj plaws rau koj daim ntawv thov.
