The Super 70 is a new type
of steel developed through multiple recursive analyses of Nippon Koshuha's
long experience in the high-speed steel industry and users, evaluations
via a computer.
Features
of S70
Hardened at temperature below 1200
to obtain the maximum hardness of HRC70 as the soluble high-speed
steel.
Appropriate component design ensures finer structure and well-balanced
hardness and tenacity.
Almost the same machinability as that of the steels currently
in use.
