Ob leeg stainless hlau thiab cov cuab yeej steel sib txawv hauv cov khoom. Qhov sib txawv no yog vim qhov txawv ntawm lawv cov ntsiab lus. Chemically, cov cuab yeej hlau yog cov pa roj carbon alloy nrog lwm cov hlau alloying xws li tungsten, chromium, molybdenum, thiab vanadium.
Piv txwv li, vim muaj cov carbides hauv cov cuab yeej hlau, nws yog qhov ruaj khov, ua haujlwm tau zoo, thiab tiv taus hnav thiab tsim kua muag. Feem ntau, cov cuab yeej steel yog tawv dua nrog lub zog tensile zoo dua li cov hlau tsis muaj steel. Qhov no ua rau lawv zoo tagnrho rau kev tsim cov cuab yeej txiav hnyav. Ntawm qhov downside, qhov tsis muaj lossis txo cov ntsiab lus chromium ua rau cov hlau no ua rau corrosion.
Tsis tas li ntawd, stainless hlau yog chromium-nickel alloy nrog npib tsib xee, nitrogen, titanium, sulfur, molybdenum, thiab silicon li lwm yam alloying ntsiab. Nws muaj xeb thiab corrosion kuj vim muaj cov chromium. Dab tsi ntxiv, nws feem ntau muaj qhov du, ci ntsa iab, thiab ci ntsa iab.
