Steel granulate

Steel granulate

Steel granulate is one of the frequently used abrasive materials. Due to its properties blasting with it is very effectively and effective. It is made of a steel alloy with a medium percentage of carbon, sulfur, phosphorus and manganese. It is a material with high durability. It has the advantage that it cleans the surface but does not roughen it. At the same time it is more gentle to blasting equipment. It is generally used in scaling and welding products, rust cleaning and shotpeening.
