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.

Prat area of sanple
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
