<p>Stainless steel for engine gaskets with a high fatigue strength and a high resistance to permanent set in fatigue, obtained by cold rolling stainless steel at a draft of not less than 40 %, annealing it at not lower than 700° and not higher than 900 °C, temper-rolling the annealed steel at a draft of not less than 40 % to form the annealed metal structure into a mixed structure consisting of a recovery non-recrystallized structure or a recovery non-recrystallized structure and a recrystallized structure.</p> |
