ABSTRACT:
A process for making and using machine parts which in their function are exposed to severe stress from sliding superficial friction and machine parts produced thereby are described. The parts are made from an iron-based alloy which includes the following elements, in weight %: 0.35 to 1.0, preferably 0.4 to 0.8% C; up to 1.0% Si; up to 1.6%, preferably 0.3 to 1.4% Mn; 0.10 to 0.35, preferably 0.12 to 0.29% N; up to 1.0, preferably up to 0.8% Al; up to 2.8% Co; 14.0 to 25.0, preferably 16.0 to 19.0% Cr; 0.5 to 3.0, preferably 0.8 to 1.5% Mo; up to 3.0, preferably up to 1.5% Ni; 0.04 to 0.4, preferably 0.05 to 0.2% V; up to 3.0% W; up to 0.18% Nb; and up to 0.20% Ti. The total concentration of carbon and nitrogen results in a value of at least 0.5% and at most 1.2%, preferably at least 0.61% and at most 0.95%, with the remainder being iron and metallurgically required admixtures for the production of machine parts. Plunger pistons and piston rings of the above alloy, may optionally contain superficial hard layers, have especially advantageous usage properties.
