Particularly adapted to extreme conditions of usage combined with impact and pressure.

PROPERTIES: At the stage of delivery and at ambient temperature: hyper hardened, it is a highly competitive austenitic steel. The roughness is in the range of 200-250 HB, whereas under the action of abrasives shocks at high speed, the surface hardens and reaches levels of 480-550 HB. (Mechanical energy transforms the austenitic structure of the surface at the stage of delivery in martensitic carbides)

Reason for shot blasting: The main applications are located in Cleaning and deburring moulded, stamped, forged and heat-treated parts.

Its use depends on the presence of shocks or high local pressure, able to produce hardening.

The treatment by impact generally called shot blasting, sanding, shotpeening is a technique of mechanical treatment of surfaces.

It is used in almost industrial sector:

Improvement of the productivity: The process of loadingunloading can be automated, robotised, depending on the frequency and number of type of parts to treat.

The quality of a treatment by impact depends on a set of parameters.

The roughness is directly linked to these parameters and above all on the shape of the projectile. If it is spherical or angular, the roughness type obtained will be different, it will have various aspects on the surface treated.

Choice of criteria For example, on an anticorrosive coating, the type of roughness to obtain will have to be defined depending on 3 criteria: - The characteristic of the material to project, - The system of spitting planned, or the application process, - The thickness foreseen for the coating which will be applied (the value "Rt" cannot be superior to the half of the thickness). The roughness will then be defined by 3 parameters "Ra" - "Rt" - "Rz" to which will be added the notion type linked to the projectile, "angular" or "spherical".

The process of spitting, the material to spit and the strength of the impact will be determined depending on the criteria of roughness to obtain.

Similarly, its conception will be monitored so as not to show zones of abrasives retention which could be detrimental to the goal sought by the shot blasting process for de-scaling or pre tension.

Shot (angular)

Abrasive choice

Important note After treatment by impact done before anticorrosive coating, a surface will be qualified by its degree of care (level of cleanliness) and its roughness (adherence guaranteed).

The preparation treatment and the surface coating time frame implementation have to be delayed to the minimum extent possible. Indeed, surfaces treated by impact are particularly sensitive and reactive to atmospheric conditions. In order to avoid condensate, we will endeavour to make the coating on a substrate at which the temperature is at least superior to 3°C compared to the dew point.
