Astralloy 8000® is an advanced abrasion-resistant steel with a good compromise between abrasion resistance and toughness (crack resistance) in extreme applications. It has a wear life which is over 50% higher than 500 HB conventional water quenched steels. Astralloy 8000 capitalizes on an innovative metallurgical concept, based on a specific chemical analysis. This chemical analysis is combined with a dedicated heat treatment conducted by oil quenching. The successful use of Astralloy 8000 for wear parts in various industries is a result of:- a superficial hardening following a very efficient work hardening capability in service, governed by a metallurgic phenomenon called TRIP effect (Transformation Induced by Plasticity).
- a very fine and homogeneous dispersion of hard particles in steel (mainly chromium, molybdenum and titanium microcarbides) giving the material its extremely high abrasion resistance
Astralloy 8000 processes (forming, machining) much better than the existing 500 HB resistant steels. Astralloy 8000 is known as the best compromise for severe applications where exceptional abrasion, impact, heat and moderate corrosion are requested in service. Astralloy 8000 is currently used in industries such as mining, quarries, cement and concrete, iron making, steel processing, recycling, earthmoving, and dredging.Information provided by Astralloy, a Nucor Company. |
