Nov yog qee cov ntsiab lus tseem ceeb los qhia txog 440C stainless hlau tiaj tiaj bar:
1. Cov khoom xyaw: 440C stainless hlau tiaj tiaj yog feem ntau yog tsim los ntawm chromium (16-18%), carbon (0.95-1.20%), thiab me me ntawm lwm yam khoom xws li manganese, silicon, thiab molybdenum.
2. Kev Tiv Thaiv Kev Hnav: 440C stainless hlau tiaj tiaj yog lub npe nrov rau nws qhov kev tiv thaiv kev hnav zoo heev, ua rau nws tsim nyog rau cov ntawv thov uas muaj cov ntaub ntawv abrasive, cov cuab yeej txiav, cov kabmob, thiab cov khoom tiv thaiv kev hnav.
3. Kev Tiv Thaiv Kev Xeb: Txawm hais tias yog cov hlau tsis muaj carbon ntau, 440C ua rau pom kev tiv thaiv kev xeb zoo.
4. Kev Nyuaj Siab thiab Lub Zog: 440C stainless hlau tiaj tiaj muaj qhov nyuaj zoo heev thiab muaj zog siab, muab kev ruaj khov thiab lub neej ntev hauv cov ntawv thov uas xav tau.
