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 15-30% by weight of Cr, 0.5-5% by weight of each of at least one of Mo, W and V 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 chromium carbides. The invention also relates to a method for production of the iron-based powder. |
