Product Introduction

High-reliability steel shot developed for demanding shot peening applications and precision manufacturing.

S70 / S110 / S170 ST Series Steel Shot are fine-size secondary quenched steel shot abrasives developed for precision shot blasting, light surface cleaning and smooth surface preparation. Through the advanced double quenching process, these fine ST steel shot grades achieve more stable hardness, better toughness and lower breakage than ordinary steel shot. Their small particle size provides excellent surface coverage for small castings, thin metal parts, precision components and workpieces with complex shapes. S70, S110 and S170 ST Series Steel Shot are suitable for applications that require controlled impact force, low dust generation, consistent blasting performance and a clean, uniform surface finish before coating, painting or further processing.

Manufacturing Process

ST Series Steel Shot is manufactured through raw material inspection, medium-frequency melting, chemical composition testing, centrifugal atomizing, drying, sizing, cleaning, shape selection, secondary quenching, tempering, fine screening and packaging.

The core advantage of ST Series Steel Shot comes from its secondary quenching process. After the steel shot is formed and preliminarily screened, it undergoes an additional quenching treatment to improve internal structure stability, hardness uniformity, toughness and impact resistance. This process helps reduce breakage and dust generation during repeated blasting cycles.

After secondary quenching, the steel shot is tempered to reduce internal stress and enhance durability. Through strict screening and quality inspection, ST Series Steel Shot delivers stable blasting performance, longer service life and consistent surface treatment quality for high-end shot blasting applications.

Manufacturing Process of ST Steel Shots

Advantages

 

1. Fine Cleaning with Stable Surface Coverage

S70, S110 and S170 ST Series Steel Shot are fine-size secondary quenched steel shot abrasives designed for precision cleaning and smooth surface preparation. Their small particle size provides better surface coverage on small parts, thin workpieces and complex shapes, helping achieve a more uniform blasting result.

 

2. Lower Breakage and Less Dust

The secondary quenching process improves toughness and hardness stability, reducing particle breakage during repeated blasting cycles. This helps lower dust generation, improve the working environment and reduce contamination inside the blasting machine.

 

3. Controlled Impact for Delicate Workpieces

Compared with larger steel shot sizes, S70, S110 and S170 provide lower impact force while maintaining stable cleaning performance. They are suitable for parts that require fine cleaning, controlled surface roughness and reduced risk of surface damage.

 

4. Consistent Results in Continuous Production

ST Series Steel Shot maintains stable particle shape and mechanical properties during continuous shot blasting. This helps customers reduce process variation, maintain consistent surface quality and improve production reliability for precision components and small castings.
