Abstract

In the press-hardening process, if one wishes to have soft portions in the finished product and therefore reduces the cooling rate for these portions so that the material in these portions does not obtain the same high proportion of martensite as the rest of the product, one can improve the elongation at rupture in these soft portions by using annealed sheet steel as the starting blank, even though the hot shaping is done at a temperature in which the steel is austenitic.
