Heavy-duty, conventional 8 % Chromium steel with
a very good cost-performance ratio
_ typical hardness of 60 to 62 HRc
_ maximum hardness up to 63 HRc
_ higher toughness than 1.2379 and 1.3343
Z-TUFF PM
Highly-ductile, low-alloyed PM steel for demanding
applications
_ typical hardness of 60 to 62 HRc
_ maximum hardness up to 63 HRc
Z-WEAR PM
Wear and compression resistant PM steel
_ typical hardness of 60 to 62 HRc
_ improved compression strength up to 64 HRc
_ well balanced wear/toughness combination
Z-MAX PM
Cobalt-alloyed, highly wear resistant and compression
strength resistant PM steel
_ typical hardness of 64 to 66 HRc
_ excellent wear resistance due to more than 20 %
carbide fraction in hardened state
MATURE SOLUTIONS FOR COLD WORKING APPLICATIONS
CONVENTIONAL STEEL
Carbide bands and carbide clusters lead to inhomo-
geneous tool properties and reduced tool life.
POWDER METALLURGICAL STEEL
Homogeneous carbide distribution leads to isotropic
tool properties and minimizing of distortions and
increased tool life.Conventional steel Powder metallurgical steel
Zapp Materials Engineering GmbH is the worldwide
leading distributor of powder metallurgical tool steels
for cold working applications. An intelligent material
selektion can result in considerable productivity im-
provements. Especially the use of powder metallurgical
tool steels lead due to their special properties such as
wear resistance, toughness and compression strength
to a reduction of production costs.
Zapp special steels comprise several conventional
and powder metallurgical tool steels for demanding
cold working applications. If high toughness, high
wear resistance and/or high compression strength is
required, Zapp special steels deliver unbeatable results.
All here presented steels can be PVD coated without
reducing the hardness after tempering.
