M42 Steel Round Bar
M42 steel round bar is a cobalt‑molybdenum high‑speed tool steel identified as grade 1.3247. The alloy contains 1.05‑1.15% carbon, up to 0.65% silicon, 0.15‑0.40% manganese, maximum 0.30% each of phosphorus and sulphur, 3.50‑4.50% chromium, and 0.95‑1.35% vanadium. Its density is 8.16 g/cm³ and it melts at approximately 4680 °C (2600 °F). The supplier lists the material as suitable for high‑performance cutting tools.
The grade is widely recognised for retaining hardness above 60 HRC even at elevated temperatures, making it a standard choice for aerospace and automotive machining inserts. Typical heat‑treatment involves austenitising at 1260 °C followed by rapid cooling and tempering to achieve a balance of wear resistance and toughness. In the broader industry, M42 bars are offered in diameters from 10 mm to 200 mm with tolerances of ±0.02 mm, and are normally supplied in bundled packs of ten bars per crate.
End users such as precision‑tool manufacturers, aerospace component makers and high‑speed machining centres source this bar for drills, taps and end‑mills. Dongguan Songshun maintains ready stock in standard dimensions and can ship in bulk according to buyer specifications. Buyers should confirm required heat‑treatment, packaging format and Incoterms before placing an order, as the listing does not disclose MOQ, price or lead‑time.
