EN9 | 070M55 grade steel is a medium carbon steel with good tensile strength.
Although EN9 steel is capable of through hardening by quenching and tempering , it is more commonly supplied in the untreated or normalised condition.
It possesses good wear resistance, but poor weldability.
High Peak Steels stock offer EN9 in black steel round bar, flat bar and square bar.
