Datasheets

The data sheets contain detailed information about the chemical composition of Ferro-Titanit as well as its mechanical and physical properties.

Ferro-Titanit C-Spezial

The binder phase consists of a cold work steel containing 3% chromium and 3% molybdenum. The relatively low alloy content brings about a low tempering resistance. The hardness decreases above approximately 200 °C. In comparison with the other grades, C-Spezial has the best machining properties.

Ferro-Titanit CROMONI

Supplied in solution-annealed condition. Ferro-Titanit Cromoni is non-magnetisable, even after ageing at temperatures up to 900 °C. Besides having a high wear resistance, this alloy is extremely resistant to corrosion and scaling, as well as highly tempering-resistant. This corrosion resistance is at its best with finely ground or polished surfaces.

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 performed in the solution-annealed, as-delivered condition. Subsequent age-hardening takes place at a relatively low temperature of 480 °C 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.

Ferro-Titanit Nikro 143

The matrix structure consists of a highly tough, age-hardenable nickel martensite. Finishing is performed in the solution-annealed, as-delivered condition. Subsequent age-hardening takes place at a relatively low temperature of 480 °C 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.

Ferro-Titanit S

Because of its high chromium and reduced carbon content, this grade is recommended in cases requiring elevated corrosion resistance.

Ferro-Titanit U

The binder phase of Ferro-Titanit U is roughly equivalent to the austenitic CrNiMo steel X 10 CrNiMoNb 18 10 (Mat. No. 1.4580). The material is non-magnetisable and, because of its high Cr and Mo contents, possesses excellent resistance to pitting corrosion in media containing chlorine ions. Its high titanium carbide content of 34% by weight, or 45% by volume, provides it with outstanding wear resistance. The Cr and Ni contents simultaneously give the material good scaling resistance and high-temperature strength.

The material requires no later postheat treatment.

Ferro-Titanit WFN

Because of its 13.5% chromium and 3% molybdenum content, WFN has a high tempering resistance up to around 450 °C, as well as high-temperature hardness and good corrosion resistance. The thermal expansion coefficient is

adjusted to that of steel through the 1% aluminium alloy addition. Lower stresses thereby occur when non-permanent and permanent joints are heated, reducing the risk of cracking.
