Cov txheej txheem tsim khoom ntawm stainless hlau riam, diav rawg thiab rab diav me me rau noj hmo yog tsim los ntawm ntau txoj hauv kev xws li stamping, vuam thiab sib tsoo.
Cov khoom siv hauv tsev stainless hlau tuaj yeem muab faib ua 201, 430, 304 (18-8) thiab 18-10.
430 stainless hlau:
Hlau + ntau tshaj 12% chromium tuaj yeem tiv thaiv oxidation los ntawm tej yam ntuj tso.Nws yog hu ua stainless hlau.Hauv JIS, nws yog code npe 430, yog li nws tseem hu ua 430 stainless hlau.Txawm li cas los xij, 430 stainless hlau tsis tuaj yeem tiv taus oxidation los ntawm cov tshuaj hauv huab cua.430 stainless hlau tsis yog feem ntau siv rau lub sijhawm, tab sis nws tseem yuav oxidized (rusted) vim yog yam tsis zoo.
18-8 stainless hlau:
Hlau + 18% chromium + 8% nickel tuaj yeem tiv taus tshuaj oxidation.Qhov no stainless hlau yog No. 304 hauv JIS code, yog li nws tseem hu ua 304 stainless hlau.
18-10 stainless hlau:
Txawm li cas los xij, muaj ntau thiab ntau cov tshuaj lom neeg nyob hauv huab cua, thiab txawm tias 304 yuav xeb hauv qee qhov chaw muaj kuab lom;Yog li, qee cov khoom lag luam qib siab yuav ua los ntawm 10% npib tsib xee kom ua rau lawv ruaj khov thiab tiv taus corrosion.Hom stainless hlau no hu ua 18-10 stainless hlau.Hauv qee cov lus qhia tableware, muaj cov lus hais zoo ib yam li "siv 18-10 qib siab tshaj plaws kev kho mob stainless hlau".
Raws li kev txheeb xyuas ntawm cov ntaub ntawv tshawb fawb chaw, stainless hlau tuaj yeem muab faib ua peb pawg: austenitic stainless hlau, ferritic stainless hlau thiab martensitic stainless hlau.Cov khoom tseem ceeb ntawm stainless hlau yog hlau, chromium thiab nickel alloys.Tsis tas li ntawd, nws tseem muaj cov kab mob xws li manganese, titanium, cobalt, molybdenum thiab cadmium, uas ua rau kev ua haujlwm ntawm stainless hlau ruaj khov thiab muaj xeb kuj thiab corrosion kuj.Austenitic stainless hlau tsis yooj yim rau magnetized vim qhov tshwj xeeb ntawm cov qauv hauv molecular.
