Hardox 600 and Hardox Extreme are used more and more for
punching tools, especially when high hardness over 55 HRC and up to 62 HRC is
required and a high risk of fracture exists.
Hardox 600 has a three times higher
toughness with the same hardness as conventional steel.
For punching tools, Hardox 600 is used instead of 1.2379 steel for pressure
plates and dies.
