1. A high strength and corrosion resistant ferrochrome alloy bulk, being made by sequentially applying a melting process of raw materials in a crucible and a solidification process to cast as an ingot, so as to have a hardness greater than HV400 but lower than HV900; wherein the high strength and corrosion resistant ferrochrome alloy bulk consists of, in weight percent:
39-68% Cr;
2.5-5.5% Ni;
2.5-6% C;
at most 4.5% M; and
the balance Fe;
wherein M consists of at least one additive element that is selected from a group consisting of B, Al, Si, Sn, Ti, V, Mn, Co, Cu, Zr, Nb, and Mo, and a summation of B, AL, Si, Sn, Ti, V, Mn, Co, Cu, Zr, Nb, and Mo content is less than or equal to 4,5%;
wherein a Fe/Ni ratio is in a range from 6 to 10, and a Cr/C ratio being in a range between 10 and 20; and
wherein in case of M including Si, a content of Si being smaller or equal to 1.5%.
