Reinforced steel wire shot

 

It is refined by drawing,cutting,strengthening and other processes and produced in strict accordance with vdfi-8001 /1994 in Germany and SAE j441 and ams2431 in the United States.The particle size of the

product is uniform,and the hardness and density are consistent.The hardness of the product are hv400-500, hv500-555,hv555-605,hv610-670 and hv670-740 respectively;the particle size is 0.2mm-2.0mm;the shape is round shot cutting,rounding G1,G2,G3 respectively,and the service life is 3500 to 9600 cycles.

The service life-enhanced steel shot has stronger toughness and is not easily broken, so it has a long service life and strong impact resistance. It can reach the shot blasting (blasting) strength in a faster and shorter time, and can maintain the shot blasting (blasting) strength better and longer. ; The consumption is lower during use, and the service life is 2-4 times longer than ordinary steel shots of the same specification (such as springs can increase their life by >1000%, gear life can be increased by >200%, welds can be increased by 200%, and pistons can Increased by 45-100%, wheel hub increased by >1000%, etc.).

 

The strengthening effect can obtain a cyclic strain hardening microstructure in the surface layer of the workpiece and introduce an optimized residual compressive stress field in the surface layer. At the same time, the outer surface can obtain low surface roughness, thereby increasing the fatigue life of the processed workpiece by 30%. .

 

Cleaning efficiency: Strengthened steel shot can bring higher quality of shot blasting cleaning and significantly improve cleaning efficiency. Taking conventional spring cleaning and gear cleaning as an example, the use of strengthened steel shot for cleaning is more efficient than the use of ordinary high carbon steel shot. Can be increased by more than 50%

 

Dust Emission The longer service life of reinforced steel shot will also greatly reduce the dust generated. Compared with ordinary steel shot, dust emission is reduced by at least 30%, which reduces the load of the dust removal system and extends the service life of the dust collector. , while reducing environmental pollution, it is a true green steel shot.

Main uses: Used for shot blasting cleaning, rust removal and strengthening of the surface of metal parts, and improving the fatigue life of metal parts.

Application fields It is not only used in springs, connecting rods, crankshafts, gears, rocker arms, camshafts, rails, steel plates, steel pipes and other components that are subject to alternating loads in the industrial field, but is also widely used in military industry, nuclear industry, wind power, automobile Metal surface treatment fields in motorcycle, shipbuilding, transmission and other industries
