| 铸石的主要性能是：硬度高（莫氏硬度为7～8）；耐磨性好（耐磨系数为0.09～0.14克/厘米，抗腐蚀性能强，除氢氟酸和热磷酸外，能抗任何酸碱的腐蚀（耐酸性大于96％，耐碱性大于98％）。 The main properties of cast stone are: high hardness (Mohs hardness is 7-8); good wear resistance (wear resistance coefficient is 0.09-0.14 g/cm), strong corrosion resistance, in addition to hydrofluoric acid and hot phosphoric acid, can resist any acid-base corrosion (acid resistance is more than 96%, alkali resistance is more than 98%). 铸石具有很好的耐腐蚀、耐磨性能，其耐酸碱性可达99％以上，耐磨性比锰钢高5～10倍，比碳素钢高数十倍；其莫氏硬度7～8，仅次于金刚石和刚玉。但其韧性、抗冲击性较差，切削加工困难。 Cast stone has good corrosion resistance and wear resistance, its acid and alkali resistance can reach more than 99%, its wear resistance is 5-10 times higher than manganese steel and tens of times higher than carbon steel, its Mohr hardness is 7-8, second only to diamond and corundum. But its toughness and impact resistance are poor, and cutting is difficult. |
