» 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.
