Steel shot WS

Steel shot WS

WS high-tech grit is widely used for cleaning and preparing various surfaces.

The main characteristics are:

  • cleaning of castings and cast billets from molding sands (steel and iron castings, copper and aluminum alloys);
  • descaling (forgings, stampings, parts after heat treatment);
  • surface hardening - hardening (springs / springs, shafts / rods; cast steel shot WS of special hardness 52,54,58 HRC is available for this process);
  • cleaning and surface preparation before coating.
Product name Chem. compound Medium hardness Grading Minimum true gravity measured by alcohol displacement method Variation in diameter, mm Microstructure
Cast steel shot WS Carbon 0.8-1.2%, Silicon 0.4-1.2%, Manganese 0.6-1.2%, Phosphorus ≤ 0.05%, Sulfur ≤ 0.05% 45,3 - 51,3 HRC According to TU 4196-001-78730722-2010 ≥ 7.4 0.18-2.36 completely homogeneous and fine-grained martensite

The size of the granules affects the quality and speed of processing. The more particles contained in a kilogram of product, the higher the surface cleaning rate: per unit time, a greater number of shot granules come into contact with the cleaned surface, but the shot must be of sufficient size to fulfill the set technological task.
