Specific chromium, molybdenum and carbon iron-based metallurgical powder composition capable of better compressibility and method of production
Abstract:
The present invention relates to a wear resistant iron-based powder, suitable for the production of pressed and sintered components, comprising 10-20% by weight of Cr, 0.5-5% by weight of Mo and 1-2% by weight of C. The powder is characterised in that it includes pre-alloyed water atomized iron-based powder particles and chromium carbide particles diffusion bonded onto said pre-alloyed powder particles. The invention also relates to a method of producing this powder.
