ASP 2030 (PM High Speed Steel) vs M42
Side-by-side chemical composition and mechanical property comparison.
Overview
ASP 2030 (PM High Speed Steel)
Powder metallurgy high speed steel by Erasteel (now Zapp). Co-free PM-HSS with excellent combination of wear resistance and toughness. C 1.28%, Cr 4.2%, Mo 5.0%, W 6.4%, V 3.1%. Hardness 64–67 HRC. Superior carbide distribution vs conventional HSS. Applications: end mills, drills, taps, broaches, cold forging punches, fine blanking tools. Alternative to M42 and S390.
M42
1.3247
Cobalt super high speed steel — 8% Co for maximum hot hardness (HRC 69 at 550°C). THE HSS for machining superalloys, titanium, and pre-hardened steels where M2 burns out. Mo-series (not W-series like T15). Reaches HRC 68-70 after hardening — among the hardest HSS grades. Also known as HS2-9-1-8 (EN) or SKH59 (JIS). Used for drills, end mills, taps, broaches, and milling cutters for difficult-to-machine materials.
