This page cover the En3A/En3A Chemical element, Mechanical Properties, En3A Datasheet, Cross Reference of En3A Mainly used for Wrought steels for mechanical and allied engineering purposes.

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 ...

070M20 grade steel is a general purpose mild steel for welded or riveted structures, forgings, machined parts, hot pressing, etc. This steel will withstand a moderate amount of cold deformation and only offers low strength, but good machinability.

EN3A | 070M20 is a general engineering steel, suitable in applications where heavy stresses and heat treatment are not involved, such as welded and riveted structures, forgings, machined parts and hot pressing. High Peak Steels stock this in a range of sizes and shapes. It is a bright drawn, or turned, mild steel with good machinability.

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.
