EN14A (150M19)Â is a low carbon manganese steel which is weldable and has good impact resistance.
It is a medium tensile steel and is capable of thorough hardening by quenching and tempering but it is normally supplied in the as rolled, untreated or normalised condition. EN14A machines like mild steel. More recently, EN14 has been superseded by S355 steel, which offers improved structural performance and, due to its popularity, has become more readily available across a wide range of sizes.
