Nov yog qee cov ntsiab lus tseem ceeb los qhia 440C stainless hlau tiaj li:
1. Kev sib xyaw: 440C cov hlau stainless hlau tiaj tiaj tus bar yog feem ntau tsim ntawm chromium (16-18%), thiab lwm yam me me ntawm lwm yam xws li manganbe, silicon, thiab molybdenum.
2. Hnav tsis kam: 440C stainless hlau tiaj tiaj tus thawj bar yog cov khoom lag luam tiv thaiv, txiav cov cuab yeej, bearings, thiab hnav-resistant Cheebtsam.
3. Corrosion Kuj: Txawm tias yog cov hlau roj carry stainless, 440C cov khoom pov thawj zoo corrosion tsis kam.
4. Hardness thiab lub zog: 440C stainless hlau tiaj tus bar muaj lub hardness zoo heev thiab muaj lub zog siab thiab ntev hauv kev thov cov ntawv thov.
