Steel shot is a spherical particle made from special materials and subjected to special heat treatment. It is often used for descaling and rust removal of steel workpieces before painting, and centrifugal shot blasting equipment is often used in this case. The spherical shape and lower hardness prevent the steel shot from causing significant wear on the equipment. How many types of steel balls are there? Let's take a look with the editor today.

1. Steel Ball
The hardness of steel balls is generally HRC40~50. When processing hard metals, the hardness can be increased to HRC57~62. They have good toughness and a service life several times longer than cast iron pellets, making them widely used.
2. Cast iron pellets
The hardness of cast iron pellets is HRC58~65, which is very brittle, easily broken, has a short lifespan, and is not widely used. Mainly used in places where high shot peening intensity is required.
3. Glass Ball
The hardness of glass pellets is lower than the first two types of pellets, mainly used for stainless steel, titanium, aluminum, magnesium, and other situations where iron contamination is not allowed. It can also be used for secondary treatment after steel shot blasting to remove iron contamination and reduce the surface roughness of parts.
