Bearing steel grit

1. Production specification: G10,G12, G14, G16, G18, G25, G40, G50, G80

 

Name		Cast steel grit
chemicals	C	0.95~1.05 %
	Mn	0.35~1.20%
	Si	0.40~1.20%
	S	≤0.05%
	P	≤0.05%
	Cr	0.5%~1.65
Average hardness		>40-50HRC ≥53-60HRC ≥60HRC
Hardness variety		±3.0HRC or ±40HV
Microstructure		Uniform tempered martensite or tempered troostite + dispersed carbide
Minimum density		≥7.5g/cm3

 

 Usage:

1. Blast cleaning 2.Rust removal 3. Shot peening 4. Sand blasting 5. Pre-treatment

6.marble cutting

 

Hardness:

(1)>40-50HRC:

With this hardness, bearing steel grit will loses its sharp edges during shot basting process, it is particularly used for surface preparation applications

(2)≥53-60HRC:

With this hardness,Newly made bearing steel grit is angularity , the grit is gradually grinded to be round in use, its particularly suited for cleaning oxide skin, pre-treatment of surface or reinforcement.

(3) ≥60HRC:

High hardness, sharp edges remain during operation, mainly used for marble cutting,characters: stable and reliable performance,even size , good abrasion resistance,more sharp for cutting, cut fast, and make the marble with a more smooth surface.

 

Comparison for bearing steel grit and cast steel grit :

Name	Bearing steel grit	Cast steel grit
Material	Bearing steel	Steel scrap iron scrap
Abrasive resistance	With Cr alloy element, abrasive resistance high, low consumed	Alloy elements is less
Structure	Forge State, Tough Structure	Cast State
Shape	Angular	Angular with some Sphere arc
Production skill	Bearing steel crushed, double quenching	Fused and cast to be steel shot, then crush the steel shot, single quenching
Density	≥7.5 g/cm3	≥7.4 g/cm3

Advantages of bearing alloy angular steel grit: Some more details of advantage Material is bearing steel ,Cr is included, abrasive resistance is high ,good hardenabilityBearing steel grit is more energy saving, no pollution, has no casting defect .Forged state, High mechanical properties, angular shape is more sharp. high efficiency, The paint coating more even

 1.High performance price ratio. We have large production capacity, and we acquire raw materials from Chinese large size suppliers directly. These, coupled with our automatic production processes, greatly reduce our production cost. Hence, we can offer our bearing alloy steel grit at competitive prices to shipbuilding enterprises and coating service suppliers.

 2. Improve grit blasting cleanness .We produce our bearing steel grit with particle sizes meet with SAEJ827 standard. The precision controlled sizes of the steel grits allow users to control the grit blasting roughness easily and can help avoid second time grit blasting.

3.Improve worke fficiency. Bearing alloy angular steel grit is of good metallographic structure, uniform hardness, long anti-fatigue life, and high impact and wearing resistance, etc. This allows it to be recycled, help users to save steel grit consumption by 30%.

4. Improved working efficiency by energy and labor cost saving. The angular structure of our steel grit can not only improve the grit blasting surface cleanness, but also increase equipment and workers’ working efficiency by 30%. Meanwhile, it can help reduce equipment operation time and workers’ working time, thus saving on energy consumption and labor cost further.

5. Reduce dust pollution. Our alloy bearing angular steel grit is of forged state, and contains precious metal chromium which offers it good impact resistance. This helps reduce dust pollution by 30%, which can help ensure the smooth and safe operation of electrical machines, extend the service time of equipment, and operator and workers’ health.
