Characteristic Properties

Ferro-Titanit Nikro 128

The matrix structure consists of a highly tough, age-hardenable nickel martensite.
The chromium content of 13.5% provides good corrosion resistance.
Finish-machining is peformed in the solution-annealed, as-delivered condition. Subsequent age-hardening takes
place at a relatively low temperature of 480℃ and can be conducted, for example, in a convection air furnace or an electrically
heated chamber furnace.
The workpiece remains extremely true-to-size and little prone to distortion due to the low age-hardening
temperature.

The workpiece remains extremely ture-to-size and little prone to distortion due to the low age-hardening

Ferro-Titanit WFN

Because of its 13.5% chromium and 3% molybdenum content, WFN has a high temepring resistance up to around 450℃ as well as high-temperature hardness and good resistance.
The thermal expansion coefficient is adjusted to that of steel through 1% aluminium alloy addition.
Lower stresses thereby occur when non-permanent and permanent joints are heated, reducing the risk of cracking.

Applications

Ferro-Titanit Nikro 128

Good possibilities of use in the processing of abrasive plastics - as pelletizer knives, injection moulding nozzles,
dies, worms and bushes.
Also as wear-resistant rings in centrifugal pumps, charging heads and circular cutters in preserve-can filling
machines.

Ferro-Titanit Nikro 143

For all types of forming tools, etc. exposed to particularly heavy wear and bending at temperatures up to 500℃.
For wearing parts of machinery and apparatus.
Used expecially in plastic processing as pelletizing knives, extruder worms, injection moulding nozzles, etc.

Ferro-Titanit WFN

All cold work applications in cutting and forming engineering.
In particular for tools and wearing parts required to have a high temepring resistance up to 450℃ as well as
elevated corrosion resistance, e.g. guide rollers for wire rod and bar steel rolling, injection moulds for plastic
processing, jets for steam-jet equipment, valve components, tube drawing dies, extrsion dies for the manufacture
of aerosol cans.
