Definitions
- a hot-rolled flat steel product obtained according to the invention and produced according to the invention consists of a steel having the following composition (in% by weight):
- Ni 0.05-2.0%
- hot strip produced according to the invention has a structure of tempered and unannealed martensite with retained austenite content, whereby bainite, polygonal ferrite, non-polygonal ferrite and cementite may also be present in minor proportions in the structure.
- the martensite portion of the structure is at least 85 area%, preferably at least 90 area%, of which at least half is tempered martensite. Accordingly, the proportion of retained austenite in a hot-rolled flat steel product according to the invention is at most 15% by volume. In each case, up to 15 area% bainite, up to 15% each, at the expense of the rest of it
- the heating temperature TWE is preferably at least 1 150 ° C, because in this way microstructural inhomogeneities, for example, by
- the quench temperature TQ targeted during the cooling is not below the room temperature. On the other hand, it is at most 100 ° C higher than the martensite start temperature TMS at which the martensitic transformation starts.
- the partitioning time tPT is composed of the time tPR (heating ramp) required for the heating process and the time tPI provided for the isothermal hold, where tPI can also be zero.
- the maximum heating rate ⁇ 1 during the partitioning step is 1 K / s, preferably 0.075 K / s, for the setting of uniform properties both over the length and width of the flat steel product, since otherwise local irregularities occur together with reduced forming properties, in particular a worsened hole widening. It is particularly advantageous if the heating takes place at a heating rate ⁇ 1 of not more than 0.03 K / s in order to ensure optimum homogeneity of the final structure and thus best hole widening and fatigue properties.
- the minimum heating rate ⁇ 1 is for reasons of economy at 0.005 K / s, preferably 0.01 K / s.
- the protective gas used is hydrogen, nitrogen and mixtures of hydrogen and nitrogen.
- test melts A - O having the compositions shown in Table 1 were melted.
- Table 2 shows for the steels A - O the A3 - determined according to equation (1) and the martensite starting temperatures TMS determined according to equation (2).
- Called partitioning temperature TP When using a bell annealer, it is also indicated in each case whether it was used to increase (“heat”) the temperature or to keep the temperature ("hold”) constant.
- the melt M has as an example of a variant with optimized
