Nov yog qee cov ntsiab lus tseem ceeb los qhia 440C stainless hlau tiaj tus bar:
1. Composition: 440C stainless hlau tiaj tiaj bar feem ntau yog tsim los ntawm chromium (16-18%), carbon (0.95-1.20%), thiab lwm yam khoom me me xws li manganese, silicon, thiab molybdenum.
2. Wear Resistance: 440C stainless hlau tiaj tiaj bar yog renowned rau nws zoo heev hnav tsis kam, ua rau nws haum rau daim ntaub ntawv uas muaj abrasive cov ntaub ntawv, txiav cov cuab yeej, bearings, thiab hnav-resistant Cheebtsam.
3. Corrosion Resistance: Txawm hais tias yog cov hlau tsis muaj roj carbon siab, 440C pom zoo corrosion kuj.
4. Hardness thiab Strength: 440C stainless hlau tiaj tiaj bar muaj zoo heev hardness thiab siab zog, muab durability thiab ntev nyob rau hauv xav tau kev thov.
