Stainless steel Granules

Stainless steel granules (austenitic)

Key usage: Stainless steel shot is primarily used in high quality blasting surface treatment of parts (aluminium, brass, steel, stone)

Production technique: gas atomization, mechanical treatment(smooth), sieving
Composition: Cr at 18%
Structure: Austenitic microstructure is dominant
Hardness: 250 to 430 HRV
Particle shape: round shot
Particle size distribution: 45micron to 3.5mm
Key characteristic: low hardness, long life, high corrosion/oxidation resistance
Colour: silver-grey

Product families

Graninox CrLN
Granules of stainless steel at 18% . Small presence of Si. Granules have austenitic structure
Description of the material and main chemical components

Granules of stainless steel at 18% . Small presence of Si. Granules have austenitic structure

Description of the manufacturing process

Melting of alloy, gas atomisation, mechanical treatment, sieving

Typical applications

Air and Turbine blasting on parts requiring deep cleaning result still keeping low surface roughness. Normally used on aluminium, brass, copper and alloys, stainless steel and stone slabs blasting treatment

Particle shape

Granules globular round

Main characteristic

Compared to Cr-Ni variance, slightly higher hardness bringing best results when used for deep cleaning still respecting good surface roughness. Working duration and material cost is slightly lower

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 300 to 430 HV

Description of the material and main chemical components

Granules of stainless steel at 18-8% Cr-Ni. Small presence of Si and Mn. Granules have austenitic structure

Description of the manufacturing process

Melting of alloy, gas atomisation, sieving

Typical applications

Air and Turbine blasting on parts requiring soft abrasion (by round and not too hard granules), good resistance of the blasting media to rust, high durability of granules. Particularly used on aluminium, brass, copper and alloys, stainless steel and stone slabs blasting treatment

Particle shape

Granules spheroidal round

Main characteristic

Austenitic structure and round particle shape allows soft abrasion effect, high resistance to corrosion, avoidance of dust effects, low wearing of equipment, long life of media

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 220 to 350 HV, is mostly used on turbine blast machines
