Chromium-nickel-molybdenum steels for heavily loaded components
The properties of large components made of chromium-nickel-molybdenum steels, in which it is highly probable that a bainitic component is present in the structure, are determine by carbide precipitation in bainitic ferrite with continuous slow cooling. Preparation of a bainitic structure without carbide provides high impact strength and metal strength in the lightly tempered condition.
In chromium-nickel-molybdenum steels containing 0.10–0.15% carbon with cooling at a rate of 300°K/h a bainitic structure free of carbide forms.
