摘要:
A water atomised prealloyed iron-based steel powder is provided which comprises by weight-%: 0.4-2.0 Cr, 0.1-0.8 Mn, less than 0.1 V, less than 0.1 Mo, less than 0.1 Ni, less than 0.2 Cu, less than 0.1 C, less than 0.25 O, less than 0.5 of unavoidable impurities, and the balance being iron.
摘要:
The present invention concerns a method for producing powder metal parts having a densified surface. The method comprises the steps: compacting an iron or iron-based powder by high velocity compacting technique to a density above 7.2 g/cm3 sintering the parts subjecting the parts to a surface densifying process.
