Material used for the construction: Manganese steel, hardening and amagnetic, shock resistant, with high tenacity which, once processed, hardens on surface to resist to usage and distortion.

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

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 every

industrial sector:

� Aeronautic

� Automotive

� Concrete and natural stone

� Boiler making industry

� Mechanical framing

� Railways

� Steel foundry, Cast iron,

� Titan, Inconel,

� Light alloy foundry

� Forge and stamping

� Mechanics

� Metallurgy

� Naval

� Nuclear

� Petrochemical

� Plastic industry

� Spring manufacturing

� Glassmaking

PROPERTIES: At the stage of delivery and at ambient temperature : hyper hardened, it is a highly competitive austen itic steel. The roughness is in the

range of 200-250 HB, whereas under the action of ab rasives shocks at high speed, the surface hardens a nd reaches levels of 480-550 HB. (Mechanical energy transforms the austenitic struct ure of the surface at the stage of delivery in mart ensitic carbides)

Norms:

NF A 35-554 / 04 – 82 DIN: W. Nr 1.3401

Improvement of the

productivity:

The process of loading-

unloading 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.

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.

A particular care will be taken to

the geometry of the balancing

tray so as to avoid damaging

the parts during the load and

unload phase.

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.
