In the field of industrial surface treatment, material consumption rate directly determines production costs, processing accuracy directly affects product quality, and supply stability directly impacts production schedules. GP-18 High-Hardness Wear-Resistant Steel Grit, through breakthroughs in materials science and innovations in production processes, elevates hardness to the HRC 58-65 range, reduces consumption rates by over 20% compared to conventional steel grit, and combines full-range customization capabilities with ten-thousand-ton spot inventory. It provides a complete surface treatment solution characterized by High Wear Resistance - High Precision - Stable Supply for industries such as machinery manufacturing, shipbuilding engineering, construction materials, and more.
Verifiable Performance
The GP-18 series uses high-carbon alloy steel as the base material. By precisely controlling carbon content (0.85%-1.2%) and adding chromium elements (0.4%-0.8%), it significantly enhances surface hardness while maintaining material toughness. The unique micro-metallurgical structure ensures particle integrity during high-speed impact, preventing premature pulverization.
