Cov txheej txheem tsim khoom ntawm riam hlau tsis xeb, diav rawg thiab diav me me rau noj hmo yog ua los ntawm ntau cov txheej txheem nyuaj 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 kev oxidation los ntawm tej yam ntuj tsim. Nws hu ua stainless hlau. Hauv JIS, nws yog codenamed 430, yog li nws kuj hu ua 430 stainless hlau. Txawm li cas los xij, 430 stainless hlau tsis tuaj yeem tiv taus qhov oxidation los ntawm cov tshuaj lom neeg hauv huab cua. 430 stainless hlau tsis tshua siv rau ib lub sijhawm, tab sis nws tseem yuav raug oxidized (xeb) vim yog tej yam ntuj tsim.
18-8 stainless hlau:
Hlau + 18% chromium + 8% nickel tuaj yeem tiv taus cov tshuaj oxidation. Cov hlau tsis xeb no 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 paug hnyav; Yog li ntawd, qee cov khoom lag luam zoo yuav ua los ntawm 10% nickel kom ua rau lawv ruaj khov dua thiab tiv taus corrosion. Hom hlau tsis xeb no hu ua 18-10 stainless hlau. Hauv qee cov lus qhia txog cov khoom siv hauv rooj tog, muaj ib lo lus hais zoo ib yam li "siv 18-10 cov hlau kho mob siab tshaj plaws".
Raws li kev tshuaj xyuas ntawm lub chaw tshawb fawb cov ntaub ntawv, cov hlau tsis xeb tuaj yeem muab faib ua peb pawg: austenitic stainless hlau, ferritic stainless hlau thiab martensitic stainless hlau. Cov khoom tseem ceeb ntawm cov hlau tsis xeb yog hlau, chromium thiab nickel alloys. Tsis tas li ntawd, nws kuj muaj cov ntsiab lus xws li manganese, titanium, cobalt, molybdenum thiab cadmium, uas ua rau kev ua haujlwm ntawm cov hlau tsis xeb ruaj khov thiab muaj kev tiv thaiv xeb thiab kev tiv thaiv corrosion. Austenitic stainless hlau tsis yooj yim rau magnetized vim yog qhov tshwj xeeb ntawm cov qauv molecular sab hauv.
