Abstract
An iron-based powder for producing highly resistant components with a small local variation in dimensional change, by powder compacting and sintering. The powder contains, in addition to Fe, 0.5-4.5% by weight Ni, 0.65-2.25% by weight Mo and 0.35-0.65% by weight C, and optionally a lubricant and impurities. The maximum variation in dimensional change is 0.07% for a minimum density of 6.7 g/cm.sup.3.
