Process for making iron-based casting allow

摘要

An iron-based casting alloy and a process for making the alloy are provided by combining an iron-carbon-chromium system with primary carbides of vanadium, niobium, titanium, or combinations thereof without any eutectic carbides of vanadium, niobium and titanium. Eutectic chromium carbides (M7C3) are also formed without any primary chromium carbides. Proeutectic austenite can also be formed in the alloy.
