What are Stainless Steel Nitronic 50 Sheets & Plates?

Stainless Steel Nitronic 50 sheets and plates (also known as UNS S20910 / XM-19) are high-strength austenitic stainless steel flat products designed to offer a unique combination of high strength, excellent corrosion resistance, and good ductility.

Nitronic 50 is strengthened by nitrogen and manganese, making it significantly stronger than conventional stainless steels like 304 and 316 while maintaining excellent corrosion resistance.

Key Functions:

  • Provide high strength and durability
  • Resist corrosion in aggressive environments
  • Maintain toughness across a wide temperature range
  • Enable fabrication and machining

Chemical Composition of Stainless Steel Nitronic 50

Nitronic 50 has a carefully balanced composition that enhances strength and corrosion resistance.

Typical Composition:

  • Chromium (Cr): 20.5% – 23.5%
  • Nickel (Ni): 11.5% – 13.5%
  • Manganese (Mn): 4% – 6%
  • Molybdenum (Mo): 1.5% – 3%
  • Nitrogen (N): 0.20% – 0.40%
  • Carbon (C): ≤ 0.06%
  • Iron (Fe): Balance

Nitrogen significantly increases yield strength and improves resistance to pitting corrosion.
