Dab tsi yog qhov txawv ntawm 201 stainless hlau thiab 304 stainless hlau?
Ob leeg 201 thiab 304 stainless hlau yog austenitic stainless hlau, tab sis 304 stainless hlau muaj ntau dua nickel cov ntsiab lus (8-10.5%) thiab chromium cov ntsiab lus (18-20%), yog li muab superior corrosion kuj. 201 stainless hlau (nrog qis nickel cov ntsiab lus thiab siab dua manganese cov ntsiab lus) muaj zog dua, muaj zog ntau dua, hardness thiab tsim nyog. rau qhov chaw nyob sab hauv tsev nrog qis corrosive tej yam kev mob, xws li kho vajtse Cheebtsam . 304 stainless hlau, ntawm qhov tod tes, yog haum rau hnyav ib puag ncig thiab cov khoom siv hluav taws xob.
Puas yog 304 stainless hlau zoo zoo?
Ntxiv rau nws cov kev tiv thaiv corrosion, 304-qib stainless hlau kuj muaj cov khoom siv zoo heev, weldability, thiab formability. Nws muaj lub zog tensile siab heev, ua rau nws siv dav hauv ntau qhov chaw. Nws cov khoom siv kho tshuab tsuas tuaj yeem txhim kho los ntawm kev ua haujlwm txias. 304- qib stainless hlau yog nyob rau hauv kev xav tau siab hauv kev lag luam khoom noj.
201 Stainless hlau
Feem ntau muaj 201 stainless hlau yog austenitic stainless hlau. Nws cov khoom tseem ceeb suav nrog 16-18% chromium thiab 4-6% npib tsib xee. Cov yam ntxwv tseem ceeb ntawm 201 stainless hlau yog nws tus nqi qis thaum tseem tswj hwm qee qib ntawm kev tiv thaiv corrosion.
304 Stainless hlau
304 stainless hlau yog ib qho ntawm feem ntau siv austenitic stainless hlau. Nws tseem hu ua 18/8 stainless hlau, muaj ntau dua 18% chromium thiab tshaj 8% npib tsib xee, thiab yog li ntawd tsis yog -magnetic. Nws yog lub npe hu rau nws zoo heev corrosion kuj, durability, thiab zoo formability. Yog li, nws raug suav hais tias yog qib siab dua - cov khoom siv rau stainless hlau cookware.
