With its high levels of chromium, molybdenum, and nitrogen, 6 Moly
alloys have excellent resistance to a wide range of chemicals and
are especially suited for high chloride environments such as
brackish water, seawater, pulp mill bleach plants and other high
chloride process streams. They provide a cost-efficient alternative
to nickel-based alloys and titanium.

Molybdenum is a lustrous, silvery colored metal which has an
abundance of 1.5 ppm in the earth's crust. In many instances, it
shows a resemblance to tungsten with which it tends to be paired in
the transition series in the periodic table, but their chemistries
tend to show more distinct differences than might be expected.
Molybdenum has a high melting point and applications for the pure
metal take advantage of this; for example, the pure material is
used as resistance heating elements in furnaces, as filament
supports in electric lamps, and as electrodes for mercury vapor
lamps. Molybdenum is used as an alloying agent in certain grades of
steel, Permalloys and Stellites (a series of alloys which contain
varying proportions of Cr, Co, W and Mo, are very hard and are used
in cutting tools and to protect surfaces subject to heavy wear).
Low co-efficient of thermal expansion (5.1x10-6 m/m/°C) which is
about half that of most steels,
Good thermal conductivity,
Good electrical conductivity,
Good stiffness, greater than that of steel (Young’s Modulus
317MPa),
High melting point (2615°C),
Good hot strength,
Good strength and ductility at room temperature,
High density (10.2 g/cm3)
Molybdenum's ability to withstand high temperatures and maintain
strength under these conditions are responsible for the fact that
molybdenum finds most of its application at elevated temperatures.
In fact, it can work at temperatures above 1100°C (in non-oxidizing
conditions), which is higher than steels and nickel-based
superalloys.
When exposed to temperatures in excess of 760°C in air rapid
oxidation can result. Under these conditions, the oxide layer
sublimes and the base metal is attacked. Thus, molybdenum performs
best in inert of vacuum environments.
