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
