    Most stainless steels have a high hardenability, meaning that the reconstructive transformation of austenite to (ferrite + carbides) is unlikely to happen unless the steel is cooled particularly slowly The most important features of these martensitic alloys are therefore the martensite start (M S) and finish temperatures (M F)
