Resumo
[Abstract]: This paper presents an alternative to the materials traditionally used in the manufacture
of coal mills for coating wedges. For this purpose, we designed and tested ten new austenitic steels
with medium manganese content. The thermal structural stability and hardness were evaluated
after different heat treatments. The steels were subjected to hyperquenching and tempering between
100 and 900 C. A metallographic analysis of each sample was then performed to determine their
thermal stability, and the Brinell hardness was measured. Later, wedges of two alternatives and
reference-material alloys were manufactured and installed in three types of mills. Their mass loss was
determined after 25 months and at an intermediate time during that period. One steel was selected
as an alternative material.
