Slick 6MO

Excellent corrosion resistance.

slick6mo 6 Mo is an austenitic stainless steel with a high molybdenum content. Coupled with Nickel and Copper this gives the alloy a good resistance to pitting and crevice corrosion, especially in environments containing halide ions, e.g. chloride, bromide and fluoride solutions.

  • UNS N08926 may offer a cost effective solution to Nickel and Titanium alloys in these environments.
  • High strength compared to 316L and 317L austenitic stainless steels
  • Excellent ductility and impact strength at both ambient and sub-zero temperatures
  • Non-magnetic
  • Higher resistance to abrasion, erosion and cavitation erosion than 316 and 317 stainless
  • Listed in MR-01-75 for sour service oilfield applications
