070M55 is a medium carbon steel grade specified under the British Standard BS970. It is widely recognized by its equivalent designation, EN9. This unalloyed steel grade provides an excellent combination of good tensile strength, wear resistance, and toughness, making it a highly versatile material for a wide range of engineering applications. You will find it is one of the most commonly used general-purpose steels for creating components that require higher strength and durability than mild steel can offer.
We supply 070M55 carbon steel in either an as-rolled, annealed, or normalized condition. This ensures the material is readily machinable and prepared for subsequent heat treatment processes like hardening and tempering. Its balanced properties make it suitable for manufacturing critical parts such as shafts, gears, axles, and various industrial tools. By choosing 070M55, you select a cost-effective and reliable material that delivers consistent performance in demanding mechanical environments.
