Abstract
Powder metallurgically produced ferritic stainless steel articles are strengthened by alloying the ferritic material with a small amount of nickel (up to 3.0% by weight). Alloying is carried out by either admixing nickel powder to the ferritic alloy powder or by pre-alloying the stainless steel powder with nickel. Conventional sintering procedures, either in a hydrogen atmosphere or in a partial vacuum, are applicable. High strength stainless steel parts made in this manner are suitable for demanding applications, including automotive exhaust flanges and HEGO bosses.
