steels. It retards softening at
elevated temperatures and is therefore used in
boiler and pr essure vessel steels, as well as
several grades of high speed and other tool steels.
Molybdenum improves the corrosion resistance of
stainless steels. In HSLA steels, it produces
acicular ferrite structures. Molybdenum is the basis
for several of the as-rolled dual phase steels used
in automotive applications. While molybdenum may
frequently be used interchangeably with chromium and
vanadium, in many instances the properties it
imparts are unique. As a result, its use has
expanded considerably over the past several decades,
with demand often outreaching supply.
