The development of the chemical composition of the economy doped chrome and manganese iron for lining the feed chute and the end walls of the gondola hopper 22-471 carrying the abrasive materials

Resumen

In the article the optimization of chemical composition of the wear-resistant economically alloyed Cr-Mn cast irons microalloyed with aluminum is realized by means of the quasi-D-optimum plan ?f Pesochinski over the mechanical and microstructural parameters, which characterize the operational properties of alloys.
