12th Tooling Conference & Exhibition - Tooling 2022

The development of martensitic steels suitable for exposure to corrosion with simultaneous wear attack is a challenging task, as corrosion and wear resistance are opposite properties in terms of alloying. With the development of NbC-containing corrosion-resistant steels, it has been possible to combine these properties. Due to its higher hardness, NbC increases the wear resistance of the steel...

The powder metallurgical incorporation of hard phases in steel matrices is an established concept to form a metal matrix composite with excellent mechanical properties. Especially TiC has been extensively used in a wide variety of steel matrices in the past. This is primarily due to its high hardness and decent bonding behavior towards steel matrices. While the stability of TiC particles is...

To predict the solidification and product properties of tool steels with complex chem-ical compositions, an understanding of the transformation behaviour during and after solidification, depending on the chemical composition, is crucial. Therefore, the qua-ternary Fe-C system with 10 w.t.-% Cr and 3% W (subsystem of cold work steels, with M7C3 and M23C6 carbides) and the Fe-C system with 6% W...

As most steelmakers, Erasteel is fully involved in decreasing its CO2 and environmental footprint. Erasteel already produces its high-speed steel using 90% recycled material and has the ambition to reach 100% in near future. The today’s remaining 10% are mainly metallic oxides (V2O5, MoO3) or ferro-alloys (FeW, FeCr, FeSi) and cobalt (Co). The total life assessment shows that producing from...
