Starc Metals stands out as a trusted manufacturer and supplier of M2 Steel Bars and Rods right here in Canberra, Australia. We specialize in high-speed steel products that are crafted for exceptional hardness, wear resistance, and cutting performance. Our M2 steel bars and rods are celebrated for their remarkable toughness, edge retention, and ability to resist softening even at high temperatures, making them perfect for precision tooling and machining tasks. At Starc Metals, we prioritize consistent quality, a fine surface finish, and precise dimensional accuracy, ensuring our customers receive materials that excel in demanding manufacturing settings.
Typically, M2 Steel Bars and Rods are made up of 0.85% carbon, 4.0% chromium, 5.0% molybdenum, 6.0% tungsten, 2.0% vanadium, along with a touch of cobalt and manganese. This well-balanced alloy composition endows M2 steel with outstanding hardness, strength, and wear resistance, even when faced with high thermal and mechanical stress. After proper heat treatment, the steel can reach a hardness of up to 65–67 HRC while still maintaining good toughness and red hardness, which helps it keep its cutting edges sharp at high speeds.

Yes, M2 steel can be welded, but it requires preheating and post-weld heat treatment to prevent cracking and ensure good weld strength due to its high hardness and wear resistance.
M2 steel rods are available in various sizes, typically ranging from 1/16" to 3" in diameter. Common finishes include bright, polished, and cold-drawn for enhanced surface quality and performance.
M2 steel bars are typically sized by diameter and length, with standard diameters ranging from 6 mm to 100 mm. Lengths usually vary from 3 meters to 6 meters.
M2 Steel Bars and Rods are commonly utilized in the production of drills, milling cutters, reamers, taps, saw blades, punches, and dies, thanks to their superior cutting capabilities and thermal stability. They also find applications in the automotive, aerospace, and heavy engineering sectors for components that demand high wear resistance and precision. The unique blend of toughness, edge stability, and machinability makes M2 steel a go-to choice for high-speed tooling applications. With their reliable performance and durability, M2 steel bars and rods are indispensable materials for precision toolmaking and industrial manufacturing.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
