Description
|
|
0-6
is an oil-hardening cold work steel which has outstanding machinability
resulting from small particles of graphitic carbon uniformly distributed
throughout the steel. These particles increase resistance to wear
and galling in service. For an oil-hardening steel, 0-6 holds size
well during heat treating.
