Engineered Steel Shots for Effective Surface Preparation
Overview
Steel shot is a type of abrasive material used in various surface preparation processes, such as cleaning, deburring, and shot peening. It consists of spherical grains made of hardened steel, which are utilized to remove surface contaminants, enhance metal surfaces, and prepare surfaces for further treatment.

Applications
Surface Cleaning: Removal of rust, scale, paint, and other contaminants from metal surfaces.
Shot Peening: Inducing compressive stress on metal surfaces to enhance fatigue resistance and strength.
Deburring: Removing burrs and sharp edges from metal parts to improve safety and finish.
Surface Preparation: Prepping surfaces for coating or painting by creating an optimal surface profile.
Advantages
Durability: Steel shot is highly durable and can be reused multiple times before degrading.
Efficiency: Provides quick and effective cleaning and surface preparation.
Cost-Effective: Long lifespan and reusability reduce overall operational costs
Consistency: Produces uniform surface finishes due to the spherical shape of the grains
Grades and Sizes
Steel shot comes in various grades and sizes to cater to different applications and desired surface finishes. Common grades include S-70, S-110, S-170, S-230, etc., with the number indicating the shot size.
Safety and Handling
Protective Equipment: Operators should wear appropriate protective gear, including gloves, goggles, and respirators, to avoid inhalation of dust and contact with skin.
Storage: Store in a dry, cool place to prevent rusting and contamination.
Handling: Handle with care to avoid generating dust and ensure even distribution during blasting processes.
Standards
Steel shot typically conforms to industry standards such as SAE (Society of Automotive Engineers) J444 and ISO (International Organization for Standardization) 11124-3, ensuring quality and consistency in its properties and performance.
