Material Notes:

Molybdenum content increases resistance to marine environments. High creep strength at elevated temperatures and good heat resistance. Biocompatible and fabrication characteristics similar to Types 302 and 304.

Corrosion Resistance:

Better corrosion resistance than 302 and 304; resists sodium and calcium brines; hypochlorite solutions, phosphoric acid; and the sulfite liquors and sulfurous acids used in the paper pulp industry.

  • Principal Design Features
    This austenitic stainless steel has an increased molybdenum content to increase its resistance to corrosion when compared to other 300 series alloys. It will resist scaling at temperatures up to 1600 F (871 C) and maintains good mechanical properties and creep strength at high temperatures.
  • Applications
    Widely used in industry, it was initially designed for paper mill machinery. It   has been used in marine environments and a wide variety of general   industrial components.
  • Forms & shapes
    Wire, Sheet, Plate, Strip, Round Bars, Hexagonal, Flats, Square, Angle, Channel, Blanks, Tubes, Billets, Pipes, Pipe Fittings, Forging Rings, Special Shape Forgings, Fasteners Etc.
