Stainless hlau lauj kaub yog nrov vim lawv muaj zog corrosion kuj, durability, thiab ci tsos.
Stainless hlau yog hlau -raws li alloy muaj 12% mus rau 20% chromium (Cr). Chromium plays lub luag haujlwm tseem ceeb hauv stainless hlau; Nws reacts nrog oxygen los ua ib tug tuab oxide zaj duab xis (passivation txheej), tiv thaiv cov hlau substrate los ntawm oxidation thiab yog li txhim kho nws xeb kuj thiab corrosion kuj.
Qee lub lauj kaub hlau stainless kuj muaj npib tsib xee (Ni) txhawm rau txhim kho lawv cov kev tiv thaiv corrosion thiab kev ua haujlwm. Stainless hlau tuaj yeem muab faib ua ntau pawg raws li nws cov microstructure, suav nrog austenitic stainless hlau, ferritic stainless hlau, martensitic stainless hlau, thiab dichromatic stainless hlau. Ntawm cov no, austenitic stainless hlau yog cov khoom siv tseem ceeb rau cookware vim nws qhov kev ua tau zoo tag nrho.
