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.

BENEFITS of 6% MOLY
  • High resistance to pitting, crevice and general corrosion.
  • Very high resistance to chloride stress corrosion cracking.
  • 50% stronger than 300-series austenitic stainless steels.
  • Excellent impact toughness.
  • Excellent workability and weldability.
6% MOLY APPLICATIONS
  • Seawater handling equipment; heat exchanger, cooling water pipes
  • Pulp mill bleach systems; drums, vats and press rolls.
  • Tall oil distillation columns and equipment
  • Chemical processing equipment
  • Food processing equipment
  • Desalination equipment
  • Flue gas desulphurization scrubbers
  • Oil and gas production equipment
  • Tanks and pipelines for various chemicals with high halide levels

Moldydenum General Information

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).

Molybdenum Key Properties

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.
