Steel shot is a spherical particle made from a special material that has undergone special heat treatment. Firstly, melt the steel block, and then spray the molten steel with high-pressure water to form particles. Heat the formed pellets again for purification and homogenization, and then rapidly cool them. The product features of the steel shot introduced below: After quenching, the shot body is dried and reheated and tempered in the furnace to achieve the applicable hardness. The tempered steel shot is divided into different grades of products that meet SAE standards through the mechanical sieve of the shot blasting equipment.
Moderate hardness, strong toughness, impact resistance, long service life, up to 2000-2900 times, good rebound, fast cleaning speed, low consumption, no damage, fast cleaning speed, good technical effect. The cleanliness of the metal surface treated with this product can reach GB/T 8923-1989; The surface roughness is rz=10-150 microns, and the hardness can be increased to HRC 57-62 by processing hard metals.
They have good toughness and a service life several times longer than cast iron pellets, making them widely used. Steel shot has high density, few disadvantages, narrow particle size distribution range, good metallographic structure, and superior mechanical properties after heat treatment. The toughness, fracture resistance, and fatigue resistance of steel shot are greatly improved, with high reuse rate, low consumption, and significant economic benefits. Steel shot can be widely used for surface strengthening and surface finishing operations of shot peened mechanical parts, and then sprayed onto steel structural parts. Thus increasing the specific surface area of the metal surface and improving the surface adhesion of the coating has significant economic benefits. Steel shot is an advanced and ideal shot blasting cleaning method for strengthening metal abrasive rust removal both domestically and internationally.
