Whether you need round bars, plates, sheets, billets, or cut-to-size blanks, our EN9 Carbon Steel products are sourced from reputed international mills and supplied with complete Mill Test Certificates (MTCs) for guaranteed quality and traceability.

With its balance of strength, wear resistance, and toughness, EN9 is one of the most widely used medium carbon steels in the engineering and automotive industry.

What is EN9 Carbon Steel?

EN9 (BS970 070M55) is a medium carbon steel grade containing about 0.50–0.60% carbon. It is commonly used where better mechanical properties are required than EN8 (080M40) but where alloy steels are not necessary.

Key characteristics of EN9 include:

• High surface hardness (after heat treatment)
• Excellent wear resistance
• Good toughness for mechanical parts
• Reasonable machinability and workability
• Suitable for induction hardening and tempering

This makes EN9 particularly useful in applications where components are subjected to high stress, repeated loads, and sliding wear.
