Core Advantages
Exceptional Wear Resistance
GL 50 utilizes special heat treatment processes, maintaining stable hardness within HRC 56-60. In practical heavy equipment manufacturing applications, its consumption rate is 35%-40% lower than ordinary steel shot and grit. One mining machinery manufacturer reported a 38% increase in treatment area per kg (4.5㎡) using GL 50.
Precise Size Control
Standard GL 50 available with customized particle size services:
Coarser version : For ultra-heavy scale treatment
Finer version : For special surface treatment requirements
Strict 5-stage screening process ensures over 97% size distribution concentration, providing consistent surface treatment results for industrial descaling steel grit.
Superior Material Purity
Harmful elements controlled to industry-leading levels:
Sulfur (S) ≤ 0.05%
Phosphorus (P) ≤ 0.05%
Non-metallic impurities ≤ 0.2%
Ensures no surface damage during precision workpiece treatment, making it an ideal choice for metal surface treatment steel shot.
