Stainless hlau 420
420 stainless hlau yog martensitic stainless hlau, 420 "ntug qib" martensitic steel, zoo ib yam li Brinell siab chromium hlau, qhov ntxov tshaj plaws stainless hlau. 420 muaj qee yam hnav tsis kam thiab corrosion kuj, siab hardness, nws tus nqi yog cov qib qis ntawm stainless hlau pob, haum rau cov kev cai dav dav ntawm stainless hlau hauv chaw ua haujlwm.
