Premium SERIES

High-productivity grit for desanding operations
High Performance Grit is a steel grit specially designed to improve shot blasting performance in foundries and forges. It works faster and last longer. Its capacity for removing and cleaning sands, resins or scale is unequalled.

Premium product for descaling operations in wheel-blasting
STAINIUM® is specially developed for descaling applications when little roughness is required at the end of the process. Especially available in fine grades, STAINIUM® provides a more stable operating mix.

Hybrid Shot

Premium mix for low machine wear in desanding operations
HYBRID SHOT was developed specifically to address new demands for desanding in foundries and descaling in forges and wire drawing plants. By reducing machine wear it helps to reduce maintenance costs while at the same time achieving remarkable performance in terms of cleaning.

STELUX® is a stainless steel abrasive media
STELUX® is used for surface cleaning, preparation and finishing of non-ferrous metals, stainless steel castings or forgings, as well as granite and marble. STELUX® is provided in two different grades: C (Chromium stainless steel shot) and CN (Chromium - Nickel stainless steel shot).

Quenched and tempered, it is a spherical product of hypereutectoid steel (C ≥ 0,85%). Perfectly controlled heat treatments provide it with optimum resilience and resistance to fatigue.
This type of shot is used in all applications where the desired effect is for mass and maximum bounce as well as for shot peening.

A cast steel angular grit is produced by crushing specially heat treated oversize shot pellets. It is utilised for blast cleaning or surface preparation.

Quenched and tempered, angular when new, this grit rapidly rounds off in use and is particularly suited to descaling applications.

Quenched and tempered, although harder than GP steel grit, GL also loses its sharp edges during shot blasting and is particularly suited to descaling and surface preparation applications.

Quenched with maximum hardness, GH always remains angular in its operating mix. These abrasives are particularly effective in surface treatment processes and produce a uniform, etched finish.
For use mainly with compressed air equipment.

Steel grits WGR are special products used for the cutting of hard stone products such as granite. Ask for our commercial-technical teams.
