Abstract

Results are given for a study of the effect of hot rolling parameters on the mechanical properties of heat-treated cold-rolled product of two-phase ferritic-martensitic steel (TFMS) of grade HCT980X (EN10336:2007). Temperatures for the end of rolling and coiling are varied during hot rolling of a metal laboratory melt. Hot-rolled product obtained by different versions is heat treated by regimes modeling annealing in a continuous hot galvanizing unit (CHGU). Morphological features of structural components and excess phase precipitates in different treatment stages are studied. The effect of strip tension in a CGHU on a set of mechanical properties with a change in temperature is analyzed. Mechanical test results are used to determine the optimum heat treatment temperature range providing the required level of cold-rolled steel strength properties.
