Nitronic 50 (UNS S20910)

• Introduction of Nitronic 50
  • Nitronic 50 Stainless Steel is a high Nitrogen, Molybdenum bearing austenitic stainless steel that provides corrosion resistance superior to Types 316L and 317L with nearly twice the yield strength at room temperature.
  • Characters
  • Nitronic 50 possesses good mechanical properties at both elevated and sub-zero temperatures. Unlike other austenitic stainless steel, Nitronic 50 does not become magnetic when cold worked or cooled to sub-zero temperatures.
• Application of Nitronic 50
  • Outstanding corrosion resistance of Nitronic 50 gives it advantage where 316L or 317L are only marginally effective in petroleum, petrochemical, fertilizer, nuclear fuel handling, paper & pulp, food processing and marine applications. The combination of corrosion resistance and strength lead to applications in marine hardware and boat and pump shafting.
  • Nitronic® 50 also sees uses in oil field production and below-out preventer hydraulic manifold blocks. NACE has included Nitronic® 50 into their standards for “Sulfide Stress Cracking Resistance…” leading to oil field “down-hole” applications and refinery application. High strength, corrosion resistance, and low magnetic permeability also make Nitronic 50 a suitable material for medical implants.
