Abstract (en)
[origin: WO2009040369A1] The present invention relates to an annealed pre-alloyed water atomised iron-based powder suitable for the production of pressed and sintered components having high wear resistance. The iron-based powder comprises 10- below 18% by weight of Cr, 0.5-5% by weight of each of at least one of Mo, W, V and Nb and 0.5-2%, preferably 0.7-2% and most preferably 1 -2% by weight of C. The powder has a matrix comprising less than 10% by weight of Cr, and comprises large M23C6-type carbides in combination with M7C3-type carbides. The invention also relates to a method for production of the iron-based powder as well as a method for producing a pressed and sintered component having high wear resistance and the component having high wear resistance.
