STAINLESS STEEL FOR ENGINE GASKET AND PRODUCTION METHOD THEREFOR

摘要

After cold rolling with a reduction of at least 40% is carried out on a stainless steel, annealing at a temperature of at least 700 DEG C and at most 900 DEG C is performed, and then temper rolling with a reduction of at least 40% is carried out. The metal structure obtained by the annealing is a recovered unrecrystallized structure or a mixed structure of a recovered unrecrystallized structure and a recrystallized structure. A stainless steel for engine gaskets having a high fatigue strength and resistance to settlement is obtained.
