Abstract (en)
[origin: EP0263373A2] The process is intended for producing mass components by conventional sintering technology and without additional hardening treatment, which are equivalent to hard castings with respect to their wear properties. They should have a surface hardness of about 50 Rockwell and only slight shrinkage. This is achieved by means of a sintered iron-nickel-copper-molybdenum alloy with added phosphorus, which has a carbon content of at least twice the added phosphorus. Essentially, its composition is as follows: 1.0-5.0% by weight of nickel (Ni) 1.0-3.0% by weight of copper (Cu) 0.3-1.0% by weight of molybdenum (Mo) 0.3-0.6% by weight of phosphorus (P) 1.0-2,5% by weight of carbon (C), remainder: iron (Fe).
