Instrumental steels for coatings
Application
Instrumental steels powders are intended for making cutting and shaping instruments using the hot compaction method, for restoring and reinforcing a die instrument by plasma transfer arc (PTS) hardfacing, creating the working surfaces of a cutting instrument, strengthening cold-rolling rollers by plasma transfer arc hardfacing, and other purposes. The powders are produced by spraying molten metal using gas.
