Industeel CREUSABRO® 8000 High Performance Wear Resistant Steel
Categories: Metal; Ferrous Metal; Carbon Steel; Medium Carbon Steel

Material Notes: Description: CREUSABRO® 8000 is a high performance wear resistant steel, exhibiting a wear resistance of 50% higher than that of conventional 500 HB water quenched steel. CREUSABRO® 8000 is using an innovative concept, based on a unique combination of chemical analysis and heat treatment procedures (oil quenching). This confers to the steel an improved wear resistant by the contribution of:
  • a very fine distribution of chromium and molybdenum microcarbides reinforcing the microstructure with the same principal as composite materials
  • a very efficient work hardening capability in service, coming from a metallurgic effect called TRIP effect (Transformation Induced by Plasticity).
In addition to its high wear resistance, CREUSABRO® 8000 still maintains a very good aptitude to processing, far much better than that of 500 HB water quenched. Application markets of CREUSABRO® 8000 are : mines, quarries, cement industries, steel making, publics works.
