Stainless steel shot in pins is obtained by cutting stainless steel wire into pieces having the same length of the diameter.
It is remarkably different from other types of abrasives for sandblasting, because grains have the same dimension and the same chemical-physical features.
Moreover, the nature of the material (drawn wire) and the production system exclude the presence of impurities and grains with inclusions, cavities, blowholes, cracks, etc.
Even if it has a cylindrical shape, this abrasive gets – during few working cycles – a spherical polyhedral shape. Such shape is then kept, even if there is a progressive reduction in the diameter, for the whole life cycle without crushing events.
Features of a pin shot are resistance to wear, abrasive power, capacity of generating and keeping a given roughness constant and, if suitably run in, capacity of producing “Almen effect” in the process of shot peening / peen forming.
Uses and Advantages
Pin shot compared to cast stainless steel shot offers the following advantages
- reduction in sandblasting time at the same finishing degree;
- remarkable reduction in abrasive consumption;
- reduction in the consumption of spares parts for the shotblasting machine with consequent reduction in maintenance costs and machine standstill times;
- reduction of dust deriving from abrasive in the plant;
- silver and brilliant look of the surface.
The wide range of available sizes and the different typologies of stainless steel allow customers to find the most suitable pin for their own finishing needs.
- austenitic stainless steel pin shot (AISI 301, 302, 304 or other analysis on demand);
- ferritic stainless steel pin shot (AISI 410, 430 or other analysis on demand);
- run in pin shot in austenitic stainless steel (AISI 301, 302, 304 or other analysis on demand).
Its ideal use is in the processes of shotblasting, sandblasting, of non-ferrous metals, of stainless steels and, last but not least, of natural stones (marbles, basalts, serizzo granites, lavic stone, etc.).
Suitably run in, it is employed in the process of shot peening and peen forming.
