070M20 Steel (EN3A)
070M20 (EN3A) is a low carbon, well-balanced unalloyed engineering steel suited where heavy stresses and heat treatment are not applied.
It is a bright drawn and turned mild steel offering excellent machinability. The “M” in the designation indicates that the steel has been fully killed (i.e., all oxygen has been removed from the steel), and the “20” refers to the carbon content, which is approximately 0.20%.
- Superior machinability
- Can be case hardened
- High ductility
- Suitable for welding
Also referred to as EN3A, EN3B or BS 970 080M20, this steel provides low strength, withstanding a moderate amount of cold deformation with suitability for welding.
