Qhov sib txawv tseem ceeb ntawm cov hlau phais thiab cov hlau tsis muaj steel yog cov hlau tsis muaj steel muaj ntau yam kev siv thaum phais hlau yog hom stainless hlau feem ntau muaj kev siv biomedical.
Kev phais hlau thiab stainless hlau yog ob hom alloys. Ib qho alloy yog sib xyaw ntawm ob lossis ntau lub ntsiab lus. Nws yog tsim los ntawm kev sib xyaw hlau nrog qee cov khoom siv (hlau lossis nonmetals, lossis ob qho tib si) kom tau txais cov khoom siv uas muaj cov khoom zoo dua qub piv rau cov hlau qub. Surgical steel yog ib hom stainless hlau muaj txiaj ntsig hauv kev siv biomedical. Stainless hlau yog cov hlau alloy uas muaj cov ntsiab lus chromium siab. Ob hom hlau no muaj txiaj ntsig zoo rau ntau daim ntawv thov vim lawv cov khoom tiv thaiv corrosion thiab lub zog zoo.
Surgical Steel yog dab tsi?
Kev phais hlau yog hom stainless hlau muaj txiaj ntsig hauv kev siv tshuaj lom neeg. Muaj qee qib ntawm cov hlau no, suav nrog austenitic SAE 316 stainless hlau thiab martensitic SAE 440, SAE 420 thiab 17-4 stainless hlau. Kev phais stainless hlau feem ntau muaj lub zog zoo thiab corrosion kuj.
Ntxiv mus, SAE 316 thiab SAE 316L muaj chromium, npib tsib xee, thiab molybdenum alloy, uas muaj lub zog zoo thiab zoo corrosion kuj. Tsis tas li ntawd, 316L yog cov pa roj carbon tsawg ntawm 316 steel. 316L steel yog biocompatible piv rau lwm hom hlau. Yog li ntawd, peb tuaj yeem siv lawv hauv kev hloov kho lub cev cog. Tsis tas li ntawd, peb tuaj yeem siv qib 316 rau kev tsim khoom thiab tuav cov khoom noj thiab tshuaj rau kev txo qis ntawm cov khoom siv hlau.
Stainless Hlau yog dab tsi?
Stainless hlau yog cov hlau alloy uas muaj cov ntsiab lus chromium siab. Yog li ntawd, nws muaj zoo corrosion kuj. Feem ntau, cov hlau no muaj txog 10.5% chromium thiab 1.2% carbon los ntawm qhov hnyav ntawm cov hlau. Nrog nce chromium cov ntsiab lus, lub corrosion kuj kuj nce. Tsis tas li ntawd, qhov sib ntxiv ntawm qee cov molybdenum rau hauv qhov sib xyaw no tuaj yeem ua rau muaj zog tiv thaiv acids. Stainless hlau muaj nyob rau hauv daim ntawv, daim hlau, tuav, xov hlau, raj, thiab lwm yam.
Cov txheej txheem ntawm cov hlau tsis muaj steel muaj ntau cov kauj ruam tseem ceeb: melting thiab casting, sib sau, kho cua sov, descaling, txiav thiab xov. Tsis tas li ntawd, cov ntaub ntawv tseem ceeb rau kev tsim khoom no yog hlau ore, chromium, silicon, nickel, carbon, nitrogen, thiab manganese. Los ntawm kev ntxiv ntau yam ntawm cov ntsiab lus no, peb tuaj yeem tau txais cov khoom sib txawv raws li qhov xav tau. Piv txwv li, ntxiv nitrogen ntxiv yuav ua rau kom lub zog tensile.
Dab tsi yog qhov txawv ntawm Kev phais Hlau thiab Stainless Hlau?
Kev phais hlau thiab stainless hlau yog qhov muaj txiaj ntsig hauv ntau daim ntawv thov vim lawv cov khoom tiv thaiv corrosion thiab lub zog zoo. Stainless hlau yog cov hlau alloy uas muaj cov ntsiab lus chromium siab. Muaj ntau qib thiab cov ntaub ntawv ntawm stainless hlau. Surgical steel yog ib qho ntawm lawv. Nws muaj kev tiv thaiv corrosion siab heev thiab yog biocompatible, tsis zoo li feem ntau lwm yam stainless hlau. Qhov sib txawv tseem ceeb ntawm cov hlau phais thiab cov hlau tsis muaj hlau yog cov hlau tsis muaj hlau muaj ntau yam kev siv thaum phais hlau yog hom stainless hlau feem ntau muaj kev siv biomedical.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm cov hlau phais thiab stainless hlau.
Summary – Surgical Steel vs Stainless Steel
Kev phais hlau thiab stainless hlau muaj txiaj ntsig zoo hauv ntau daim ntawv thov vim lawv cov khoom tiv thaiv corrosion thiab lub zog zoo. Qhov sib txawv tseem ceeb ntawm cov hlau phais thiab cov hlau tsis muaj hlau yog cov hlau tsis muaj hlau muaj ntau yam kev siv thaum phais hlau yog hom stainless hlau feem ntau muaj kev siv biomedical.
