Abstract

See full text

A high strength and corrosion resistant ferrochrome alloy bulk is disclosed, which comprises, in weight percent: 30-68% Cr, 1.5-8% Ni, 1.6-6% C, and the balance Fe and incidental impurities, of which a Fe/Ni ratio is in a range from 5 to 10 and a Cr/C ratio is in a range between 10 and 33. Experimental data reveal that, samples of the high strength and corrosion resistant ferrochrome alloy bulk all possess hardness above HV400 and excellent corrosion resistance due to the high content of Cr. As a result, experimental data have proved that the high-strength and corrosion-resistant ferrochrome alloy bulk of the present invention has a significant potential to replace conventional high-strength stainless steels, so as to be widely applied in various industrial fields, e.g., aviation, transportation, marine facility components, chemical equipment and pipe fittings, engine parts, turbine blades, valves, bearings, building materials, and so on.
