Professional High Hardness G12 Bearing Steel Grit Grinding Media for Stone Cutting

Professional High Hardness G12 Bearing Steel Grit Grinding Media for Stone Cutting. Multiple Hardness Grades: GP 40-50 HRC, GL 50-60 HRC, and GH 60-66 HRC options meet different blasting and surface preparation requirements. Bearing Steel Material: Made from bearing steel with 0.80-1.20% carbon and 0.60-1.60% chromium for stable mechanical properties and wear resistance. Strong Angular Cutting Action: Angular particles provide effective cutting performance for rust removal, descaling, cleaning, and metal surface preparation. Long Fatigue Life: Controlled material composition and metallographic structure support durable performance during repeated blasting cycles. Stable Metallographic Structure: Fine and homogeneous tempered troosite structure supports consistent hardness and reliable blasting performance. Wide Size Selection: G10, G12, G14, G16, G18, G25, G40, G50, G80, and G120 sizes cover particle diameters from 0.2 to 2.5 mm. Flexible Product Selection: Multiple particle sizes and GP, GL, and GH hardness grades allow XINYUAN to match different workpieces, equipment, and processing requirements. High Density: Minimum density of 7.4 g/cm3 supports stable impact energy for efficient blasting.
