The raw material of bearing steel sand is bearing steel. Bearing steel is high purity iron carbon alloy steel. Bearing steel is used to make balls, rollers and bearing rings. Bearing steel has high and uniform hardness and wear resistance, as well as high elastic limit. Bearing steel is one of the most demanding steel grades in all iron and steel production because of its strict requirements on the uniformity of chemical composition, the content and distribution of non-metallic inclusions and the distribution of carbides. So his price is naturally much higher than the ordinary scrap price. Bearing steel sand is broken into steel sand by forging bearing steel after direct quenching. There is no smelting process and casting defects in the manufacturing process, so it is energy-saving and pollution-free product. Compared with cast steel sand, bearing steel grit can be used as cleaning product and abrasive for manufacturing abrasive tools to polish and grind the bearing and other workpieces. Bearing steel sand contains precious metal chromium element, which enhances the anti fatigue life and wear resistance of the product itself. Through the unique production process, the product has excellent metallographic structure, full particles, uniform hardness, long anti fatigue life, impact resistance and high wear resistance, which can effectively improve the recovery utilization rate (the abrasive is gradually reduced in the process of sand blasting), so as to reduce the consumption rate of abrasive More than 30%. Bearing steel sand is a kind of high quality steel sand which can meet high standard, high requirement and high quality in the world.

The advantages of bearing steel sand over common cast steel sand are shown in the following aspects

1. The composition of bearing steel grit is stable.

2. Bearing steel sand has high toughness and tensile strength.

3. Bearing steel sand overcomes all the weakness of cast steel grit, without air hole and breakage.

4. Long service life.

Advantages of using bearing steel sand:

1. After cleaning, the surface color of the workpiece is silver white.

2. Less environmental pollution.

3. The labor intensity of workers decreased.

4. High efficiency, less pill consumption and lower production cost.
