Description
532 750 2 Det har överraskande visat sig att man får en större duktilitet i de ohärdade partierna när man använder rekristalliseringsglödgat ingångsmaterial trots att man i presshärdningsprocessen vänner hela ämnet till austenitiseringstemperatur. Uppfinningen definieras av patentkraven. 532 750 2 It has surprisingly been found that greater ductility is obtained in the uncured portions when using recrystallization annealed starting material despite the fact that in the press hardening process the whole substance is used at austenitization temperature. The invention is claimed by the claims.
