There are all kinds of shapes for instanFire Control ce square shape, rectangle shape, trapezoid and some special shape. It is the ideal wear-resistant materials for wear resistant grinding equipment such as oil, chemical, mine, steel and electricity industry. It has advantages of various types, high hardness(Rockwell hardness is HRA80-90), excellent wear resistance, impact resistance, corrosion resistance, good heat resistance and light weight. It can save the maintain cost, extend the life of machines.Drilling Rig Performance IndexItem/ProductHA 92HA 95ZTAZRAL2O3(%)92±0.595±0.576±0.5ZrO2(%)2094.8±0.5Bending Strength(MPa)> 220> 280> 400> 1000Fracture Toughness(MPam 1/2)> 3.60> 3.90> 4.50> 7Rockwell Hardness(HRV)> 82> 88> 90> 88Wear Volume(cm³)< 0.50< 0.30< 0.15< 0.10DensSemiconductor Manufacturing & Processing Machinery ity(g/cm³)> 3.60> 3.70> 4.10> 5.90
