HSS M35
Purchase and sale of HSS M35 cobalt high-speed steel scrap and turnings for European steel mills and foundries. Fast quotations, collection across the whole territory.
Cobalt high-speed steel: a derivative of M2 with the addition of about 5% Co for greater hot hardness and temper resistance. Markets: high-performance tools, heavy-duty machining, tough materials.
- Forms scrap · turnings · chips · cut-offs
- Density ~8.15 g/cm³ (indicative)
- Hardness 64 – 66 HRC
Main elements
| Tungsten (W) | 5.9 – 6.7 % |
|---|---|
| Molybdenum (Mo) | 4.7 – 5.2 % |
| Cobalt (Co) | 4.5 – 5.0 % |
| Chromium (Cr) | 3.8 – 4.5 % |
| Vanadium (V) | 1.7 – 2.1 % |
| Carbon (C) | 0.87 – 0.97 % |
| Iron (Fe) | balance |
Indicative values according to EN ISO 4957 / ASTM A600. The presence of cobalt makes this grade valuable for recovery; composition certified for each batch.
Physical and mechanical data
| Density | ~8.15 g/cm³ (indicative) |
|---|---|
| Hardness (after quench/temper) | 64 – 66 HRC |
| Annealed hardness | ≤ 269 HB |
| Hot hardness | higher than M2 thanks to Co |
| Structure | alloyed ledeburitic (M6C / MC carbides) |
Density and hardness are indicative values; they vary with the heat-treatment condition and the analysis of the individual batch. Certified values on request.
