Nitronic 50 Stainless Steel

Nitronic 50 stainless steel, also known as UNS S20910 or ASTM XM-19, is an austenitic alloy with added nitrogen that provides numerous beneficial qualities over 316 stainless steel, including:

  • Increased strength
  • Greater corrosion resistance
  • Double the yield strength

Additionally, Nitronic 50 stainless exhibits very good mechanical properties at extreme hot or cold temperatures, and, unlike many other austenitic stainless steels, exhibits very low magnetic permeability when cold worked or cooled to sub-zero temperatures.

Forged Nitronic 50 Stainless Steel Applications and Industries

Our Nitronic 50 steel forgings serve a variety of industries which include, but are not limited to:

  • Marine
  • Petrochemical Industries
  • Nuclear Energy 
  • Paper Industries
  • Food Processing

Nitronic 50 Stainless Steel Hardness

Annealed nitronic 50 stainless steel has a Brinell scale hardness of 150, and a Rockwell hardness of B80. Nitronic 50 stainless cannot be hardened by heat treatment; cold working will increase strength and hardness.

Heat Treating Nitronic 50 Stainless Steel

Nitronic 50 stainless steel can be annealed by heating the material to temperatures between 1950-2050°F (1066-1121°C) and cooling/quenching rapidly. If used as in a highly corrosive environment, annealing should be performed at maximum temperature (2050°F) to minimize the risk of intergranular attack.

Nitronic 50 Stainless Steel Machinability

Nitronic 50's machinability characteristics are like other austenitic stainless steels. However, due to its high work hardening rate, Nitronic 50 stainless requires more power, slower speeds, and higher rigidity. Carbide-coated tooling is recommended.
