Astralloy 4800® Wear Resistant Steel
Categories:	Metal; Ferrous Metal; Tool Steel
Material Notes:	Astralloy 4800® is a wear resistant steel offering up to 50% additional in service life compared with a 400 HB water quenched steel. The steel combines several metallurgical concepts which, depending on thickness, use different combinations of an enriched chemical analysis (Cr, Mo, Ti) and controlled quenching rate. Astralloy 4800 is designed to provide the optimum combination of wear resistance, controlled hardness and ease of processing. Rather than just using a high hardness level, it achieves this state 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 TRIP (Transformation Induced by Plasticity) effect originally developed with Astralloy 8000 Reinforcement of the structure with titanium carbides The limited hardness of Astralloy 4800 makes processing operations like cutting, machining and forming no more difficult than processing 400HB water quenched steel. Astralloy 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). Information provided by Astralloy, a Nucor Company.
