Frequently Asked Questions
Steel shot is widely used for cleaning, descaling, shot peening, and preparing metal surfaces before coating. Its spherical shape ensures uniform results and superior durability compared to irregular abrasives.
Steel shot is spherical and ideal for peening and cleaning, while steel grit is angular and better for aggressive surface preparation where higher cutting action is required.
Steel shot hardness is typically classified in ranges such as 40–50 HRC, 52–56 HRC, and 56–60 HRC, depending on the application—whether for conventional cleaning or high-intensity peening.
Steel shot comes in SAE grades ranging from S70 to S930, with sizes measured in millimeters and mesh to meet specific industrial requirements.
Steel shot offers longer service life, reduced dust generation, consistent results, and cost-effectiveness compared to sand, slag, or other disposable abrasives.
Nupon Steel Shot is manufactured with strict quality control, ensuring consistent hardness, density, and performance that meets international SAE standards.
