Graninox CrNi
Graninox LN
| Product Group: | Stainless steel shot (low hardness - austenitic structure) |
| 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 |
| Main characteristic of the product Type: | 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 shape: | granules spheroidal round |
| Particle upper cut size (Full range): | 0,15 mm to 3,35mm |
| Particle upper cut size (Typical): | 0,30 mm to 2,36 mm |
| Apparent density (Typical): | |
| Recommended Pakaging: | |
| Application notes: | hardness range 220 to 350 HV, is mostly used on turbine blast machines |
| Key elements: | Fe iron, Cr chromium, Ni nickel |
| Key Processing: | Atomisation: granules |

| Product Group: | Stainless steel shot (low hardness - austenitic structure) |
| Description of the material and main chemical components: | Granules of stainless steel at 18-4% Cr-Ni with addition of 4% Cu. 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 |
| Main characteristic of the product Type: | 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 shape: | granules, globular round |
