This Hot Work Die Steel alloy is used for both ferrous and
nonferrous hot mill work roll applications. The unique
properties of this alloy combine high thermal fatigue strength
and resistance to cracking at elevated temperatures. The
microstructure consists of a uniform dispersion of alloy
carbides in a fine grain tempered martensitic matrix that
manifests enhanced wear resistance. Grade 5CR80MO also offers
the ability to achieve hardness levels beyond the standard
4CR80MO alloy for hot nonferrous applications. This property
will result in longer mill campaigns and improved retention of
finish.
