Qhov sib txawv ntawm 904 stainless hlau rooj plaub thiab 316L stainless hlau rooj plaub

Feem ntau cov khoom siv saib tuaj yeem muab faib ua cov hlau tseem ceeb xws li kub, platinum, sawv kub; Cov ntaub ntawv tshwj xeeb zoo li carbon fiber, sapphire siv lead ua, thiab lwm yam, thiab tus yuam sij rau tus nqi ntawm lub moos yog cov khoom siv ntawm lub moos, yog li nyob rau hauv ntau cov ntaub ntawv, stainless hlau saib nqi yog qhov ze tshaj plaws rau cov neeg.

Txawm hais tias nws raug hu ua stainless hlau, cov khoom siv stainless hlau saib tuaj yeem muab faib ua ob hom, ib qho yog 316L stainless hlau, thiab lwm yam yog 904L stainless hlau. Qhov txawv ntawm ob yog dab tsi? Cia peb kawm ntxiv.

316L stainless hlau
Lub ntsiab Cheebtsam ntawm 316L stainless hlau yog hlau, chromium, npib chromium, thiab yuav tsis cuam tshuam rau cov hlau tib neeg, yog li ntawd ntxiv rau kev siv los ua cov ntaub ntawv, kev siv ntawm 316L stainless hlau ua los ntawm cov saw tseem muaj ntau heev. Cov txheej txheem tsim khoom rau 316L stainless hlau yog qhov xav tau heev. Tom qab thawj casting, cov hlau yog remelted rau hauv lub tshuab nqus tsev ntim, purified kom tshem tawm impurities, thiab soj ntsuam los ntawm ib tug electron microscope kom paub meej tias qhov zoo ua ntej nws yuav siv tau los ua ib tug saib. Vim tias 316L stainless hlau yog ib qho nyuaj heev, cov txheej txheem tom ntej xws li kev ua haujlwm tseem yog qhov nyuaj, thiab cov txheej txheem muaj pes tsawg leeg tsis yooj yim li xav.

904L stainless hlau
904L stainless hlau yog tsuas yog siv rau hauv cov khoom siv xws li tshuaj reactors, seawater processors thiab lwm yam kev sib cuag nrog cov tshuaj corrosive heev, yog li cov corrosion kuj muaj zog dua 316L. Yog vim li cas rau qhov sib txawv no yog nyob rau hauv muaj pes tsawg leeg ntawm cov hlau alloy, 316L steel thiab 904L steel yog tiag tiag zoo sib xws, lub ntsiab Cheebtsam yog npib tsib xee, chromium, molybdenum, tab sis qhov kev faib ua feem yog sib txawv, thiab 904L kuj muaj ib tug me me tooj liab, yog li ntawd. corrosion kuj thiab hnav tsis kam yog muaj zog tshaj 316L, thiab ob lub zog thiab hardness thiab tsis muaj ntau qhov sib txawv. Thiab vim yog cov hlau purity siab ntawm 904L steel, nws tuaj yeem ua polished heev, yog li nws tuaj yeem tau txais cov nyhuv ci dua thiab zoo nkauj tom qab sib tsoo. Tsuas yog tus nqi ntawm kev siv 904L steel yog qhov siab, vim tias qhov kev sib tsoo ntawm 904L yog qhov nyuaj, thiab cov nqi tsim khoom kuj tseem yuav nce ntxiv. Yog tias tsuas yog rau kev tiv thaiv corrosion thiab zoo nkauj dua, thiab yuav tsum tau hloov tag nrho cov kab ntau lawm ntawm cov cav tov, qhov kev coj ua no yog qhov zoo li Rolex ua nws, yog li 904L kuj muaj lub npe menyuam yaus ntawm "labor steel".
