Abstract:
It has been found that high density articles having improved strength, corrosion resistance, better durability, and decent magnetic characteristics can be manufactured from a ferritic stainless steel powder using a novel method. This technique is especially beneficial in manufacturing parts, such as, reluctor rings, tone wheels, trigger wheels, pump impeller blades, and EGR valves, in large quantities. This method involves (1) compacting the ferritic stainless steel powder in a mold into a green article, (2) sintering the green article at an elevated temperature under vacuum or a reducing atmosphere to produce a sintered article, and (3) forging the sintered article under a reducing or an inert gas atmosphere to a density of greater than 7.5 g/cc in the presence of a graphite free lubricant to produce the high density article.

Claim (Index 2):
The method of  claim 1  wherein the lubricant is a glass based forging lubricant.
