What are Stainless Steel XM-19 Sheets & Plates?

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

XM-19 is strengthened by nitrogen and manganese, providing superior mechanical properties compared to standard austenitic stainless steels such as 304 and 316.

Key Functions:

  • Provide high strength and durability
  • Resist corrosion in aggressive environments
  • Maintain toughness at low and high temperatures
  • Enable fabrication and machining

Chemical Composition of Stainless Steel XM-19

SS XM-19 has a unique 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 strength and improves corrosion resistance.
