ASP 2060 Powder Metallurgy HSS
ASP 2060 (UDDEHOLM) — PM HSS with 10.5 % Co, HRC 67–69. Compare with M42 and T15 for high-speed slitter blades on abrasive substrates.
ASP 2060 (UDDEHOLM / Voestalpine high-speed steel grade) is a PM-produced high-speed steel with 4 % Cr, 7 % Mo, 6.5 % W, 6.5 % V, 10.5 % Co — the highest alloy content in the standard ASP series. Hardened to HRC 67–69, it is the premium grade for high-speed slitter blades on abrasive paper / film, and for cutting tools where M42/M35 wear life is insufficient.
Standard composition: C 2.30 %, Cr 4.0 %, Mo 7.0 %, W 6.5 %, V 6.5 %, Co 10.5 %, balance Fe (typical)
Hardness: Annealed HB 280–320; hardened HRC 67–70
Heat treatment: Austenitise 1,150–1,180 °C, gas quench, triple temper 540–570 °C
Properties: A powder-metallurgy HSS with very high V (6.5 %) and Co (10.5 %). Extremely high wear resistance. Hardness up to HRC 70. Toughness better than would be expected at this hardness because the powder-metallurgy process produces a uniform, fine carbide distribution. Very expensive.
Applications: Most demanding slitter blades, abrasive composite cutting, precision stamping tooling.
Cross-reference: ≈ DIN 1.3292 (similar powder HSS).
