H13 Tool Steel Technical Data
H-13
is a 5% chromium hot work tool steel designed for applications that
require extreme toughness combined with good red-hardness. H-13 will
allow an extra margin of safety in tools subject to heavy hammer
blows, and those containing deep recesses or sharp corners. Although
H-13 was designed as a hot work steel, it has solved many cold work
applications where extra toughness could be gained with some sacrifice
of wear resistance.
