Product families

Graninox Cr
Granules of stainless steel at 14% Cr. Small presence of Ni and Si. Granules have martensitic structure
Description of the material and main chemical components

Granules of stainless steel at 14% Cr. Small presence of Ni and Si. Granules have martensitic structure

Description of the manufacturing process

Melting of alloy, gas atomisation, mechanical treatment, sieving

Typical applications

Turbine and air blasting on parts requiring aggressive abrasion (stainless steel shot charcterised by medium resistance to rust). Particularly used on aluminium, brass, copper and alloys, stainless steel and stone slabs blasting treatment

Particle shape

Granules, irregular-globular

Main characteristic

Martensitic structure allows good abrasion performances at convenient material cost

Particle upper cut size (full range)

0,15 mm to 3,35mm

Particle upper cut size (typical)

0,30 mm to 2,36 mm

Application notes

Hardness range 460 to 630 HV

Graninox CrH
Granules of stainless steel at 28% Cr. Small presence of Mn and Si. Granules have martensitic structure with carbides
Description of the material and main chemical components

Granules of stainless steel at 28% Cr. Small presence of Mn and Si. Granules have martensitic structure with carbides

Description of the manufacturing process

Melting of alloy, gas atomisation, crushing, sieving

Typical applications

Air blasting on parts requiring very aggressive abrasion and high roughness surface (stainless steel shot charcterised by good resistance to rust). Used succesfully in substitution of Corundum, Garnet, Glass and Ceramic granules with definite improvement of durability and dust effect

Particle shape

Granules, angular sharp edges

Main characteristic

Martensitic structure with chrome carbides bring highest particle hardness and crushing process creates sharp particles keeping their shape over working time

Particle upper cut size (full range)

0,30 mm to 1,00mm

Particle upper cut size (typical)

0,30 mm to 1,00mm

Application notes

Hardness range 595 to 800 HV. Not suitable for turbine blasting machines
