Creusabro 8000

Significantly Better Wear Resistance than AR500 due to TRIP Effect

 

STULZ-CREUSABRO 8000

 

Typical 470 HB –» Work harden to ≳540 HB
Delivery condition : Guaranteed 430/500 HB

 

 

STULZ-CREUSABRO  8000  is known as the best solution for severe applications where exceptional abrasion, impact, heat and moderate corrosion are requested in service. It is currently used in Mining, Quarries, Cement and Concrete industries, Asphalt Plants, Steel Recycling, Earthmoving, Dredging...

» Restricted alloy elements (mainly C, Mn, B) » Specific chemical composition
» Drastic water quenching » Controlled cooling (oil quenching)
» Fully martensitic structure » Mix macrostructure:
  martensite + bainite
  + retained austenite
  » Perfect balance : high wear resistance + improvement workability
  » Wear resistance in service is a combination of:
  –» work-hardening effect (TRIP phenomenon)
  –» Presence of micro-carbides (chromium, molybdenum, titanium)
  –» Delayed tearing of metal particles (super-ductility of the retained austenite).
Wear resistance in service is a result of the hardness in the asdelivered state. It is an answer for common applications. Stulz-Creusabro 8000 is an answer for intense, specific applications.
