Creusabro® 4800 is a wear resistant steel offering up to 50% extra in service life compared with a 400 HB water quenched steel.

The steel combines several modern metallurgical concepts which, depending on thickness, use different combinations of an enriched chemical analysis (Cr, Mo, Ti…) and controlled quenching rate.

Creusabro® 4800 is designed to provide the optimum combination of wear resistance controlled hardness and ease of processing.

Rather then using just a high hardness level, it achieves this aim by using proven and controlled metallurgical mechanisms, which are more complex but more efficient than the simple effect of hardness alone :

• Work-hardening and Cr Mo micro-carbides, the basic Creusabro® concept,

• TRIP(*) effect originally developed with Creusabro® 8000,

• Reinforcement of the structure with Titanium carbides.

The limited as delivered hardness of Creusabro® 4800® makes processing operations like cutting, machining and forming no more difficult then processing 400HB water quenched steel.

Creusabro® 4800 is ideal for applications in mines and quarries, cement and the steelmaking industries, publics works and agricultural machinery. It is suitable for all types of abrasion, sliding or impact, dry or wet media including high temperature abrasion up to 350°C (660°F).
