US 2000

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.
