摘要:
The purpose of the present invention is to provide high manganese cast iron containing spheroidal vanadium carbide and method for making which is nonmagnetic as well as superior mechanical properties such as wear-resistance and toughness, and further does not require a water toughing heat treatment which has been needed when nonmagnetic high manganese steel (high manganese cast steel) is obtained by crystallized spheroidal vanadium in austenite matrix, and the high manganese cast iron containing spheroidal vanadium carbide is comprised of C 1.5˜4.0 weight %, V 6˜15 weight %, Si 0.2˜4.0 weight %, Mn 10˜18 weight %, Mg 0.01˜0.1 weight %, remaining iron (Fe) and inevitable impurities, spheroidal vanadium carbide is crystallized within a structure.
