In this article, high – chromium 280X29NL malleable white cast iron is produced by reducing the chromium content from 28.86 – 31% to 13 – 14%, adding up to 1.0% Cu, changing its chemical composition, and heat treating the alloy without reducing its mechanical properties. A new brand 280X29NL (sample 3) alloy was developed that is inexpensive and wear – resistant.
