070M55 Carbon Steel | EN9 Medium Carbon Steel Supplier in UAE – Nifty Alloys LLC 

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. 

Key Features and Benefits 

Choosing 070M55 (EN9) steel for your projects provides a distinct set of advantages rooted in its well-balanced material properties. Its reliability and versatility have made it a staple in the engineering industry for decades. When you select this grade, you benefit from a material that is not only strong and durable but also economical and easy to process. 

Here are the primary features and benefits of using 070M55 carbon steel: 

• High Surface Hardness: Through processes like flame or induction hardening, the steel can achieve a very hard surface, making it ideal for applications requiring excellent wear resistance. 
• Good Wear and Fatigue Resistance: The material's inherent toughness and ability to be hardened make it resistant to the effects of friction, abrasion, and cyclical loading, extending component life. 
• Reliable Toughness and Ductility: In its annealed or normalized state, 070M55 offers good toughness, allowing it to absorb energy and resist fracture under impact loads. 
• Excellent for Surface Hardening: The carbon content makes it highly suitable for flame and induction hardening, allowing you to create a hard-wearing surface while maintaining a softer, tougher core. 
• Good Machinability: When supplied in the annealed condition, the steel is easy to machine, enabling you to create complex parts with precision before final heat treatment. 
• Cost-Effective Performance: 070M55 provides a high level of performance at a lower cost compared to many alloy steels, making it an economical choice for a wide array of mechanical components.
