Introduction of HWS (High Wear resistance Steel)

In the early 90s ROVALMA decided to establish an R&D unit of its own in order to provide tool material solutions to applications, for which the industry had not been able to offer any solutions yet. Since then, with our broad knowledge in materials and applications and highly qualified and dedicated staff, we have been developing high performance materials with outstanding physical and mechanical properties that have enabled a broad range of industrial sectors to make a qualitative leap in production process productivity as well as regarding product properties and quality.

- Typical failure mechanisms

Fatigue

Abrasive wear

Adhesive wear

Chipping and microchipping

Plastic deformation(Sinking)

Accidents

UNIVERSAL UNIVERSAL® materials combine high hardness with exceptional levels of wear resistance and fracture toughness. The microstructure of UNIVERSAL® provides an exceptionally good substrate for functional hard coatings.
HWS HWS® materials combine high hardness with exceptional levels of wear resistance and fracture toughness. They have been specially designed for cold work applications and have been used very successfully in tools for drawing and cutting of thick UHSS and AHSS, cold forging and other demanding processes which require high wear resistance and toughness from the tool material. The microstructure of HWS® provides an exceptionally good substrate for functional hard coatings.
WOV & EWRA WOV® and EWRA® materials are cold work tool steels of high carbide content, which provide very high hardness levels, up to 70 HRc, and exceptional resistance to abrasive and adhesive wear. These materials allow high degrees of surface polishing, provide good substrates for coatings, and can provide important advantages for applications, in which very high wear resistance and hardness levels are required.
ICO ICO grades are maraging tool steels with exceptional levels of mechanical resistance and toughness. These grades have been designed for hot and cold work applications that require high levels of toughness and resistance to plastic deformation, such as, for instance, thin and long core pins, cutting tools, segments of die casting dies, etc.. ICO grades provide a very good substrate for different types and application methods of coatings, such as PVD, CVD, cold spray coating, etc..
