3. Manufacturing Techniques for Vanadis 10 Acciaio strutturale
Producing Vanadis 10 requires advanced powder metallurgy processes to control carbide distribution and ensure uniform properties—critical for its performance. Ecco il processo dettagliato:
1. Produzione primaria
- Metallurgia in polvere: High-purity iron, cromo, vanadio, and other alloy powders are mixed in precise ratios (matching Vanadis 10’s chemical composition). The mixture is compacted into green compacts under high pressure (800-1000 MPA) to form dense blanks.
- Vacuum sintering: Compacts are sintered in a vacuum furnace at 1200-1250°C for 2-4 ore. This fuses the powder particles into a solid material, eliminating porosity and ensuring uniform carbide distribution—key to Vanadis 10’s toughness.
- Fornace ad arco elettrico (Eaf): For small batches—scrap steel and alloying elements are melted at 1650-1750°C. Real-time sensors monitor composition to meet Vanadis 10’s standards, though powder metallurgy is preferred for premium properties.
- REMELLAZIONE ARCO VUOUTO (NOSTRO): Opzionale, for ultra-pure Vanadis 10—sintered ingots are remelted in a vacuum to remove impurities (PER ESEMPIO., ossigeno, azoto), further improving material uniformity and toughness.
2. Elaborazione secondaria
- Rotolando: Sintered ingots are heated to 1050-1100°C and rolled into plates, bar, or tool blanks via hot rolling mills. Hot rolling refines grain structure and shapes Vanadis 10 into standard tool forms (PER ESEMPIO., cutter bars, gli spazi vuoti).

- Spegnimento e tempera: Heated to 1020-1060°C (spento in petrolio) then tempered at 500-550°C for 2-3 ore. Aumenta la durezza a 60-64 HRC and tensile strength to 2400 MPa—used for high-wear tools like cutting dies.
3. Trattamento superficiale
- Rivestimento: Deposizione di vapore fisico (Pvd) rivestimenti (PER ESEMPIO., nitruro di titanio in alluminio, Tialn) are applied to cutting tools—reduces friction, boosts wear resistance by 2-3x, and extends tool life in high-speed machining.
- Nitriding: Nitriding a bassa temperatura (500-550° C.) forma uno strato di nitruro duro (5-10 μm) on tool surfaces—ideal for dies or cutting tools, enhancing wear resistance without compromising core toughness.
- Carburazione: Used for parts needing hard surfaces and tough cores (PER ESEMPIO., stamping die edges)—heated in a carbon-rich atmosphere (900-950° C.) Per aggiungere carbonio alle superfici, then quenched for extra hardness.
