Nitronic 50 Stainless Steel

Properties of Nitronic 50 Stainless Steel

Nitronic 50 stainless steel is an austenitic alloy with nitrogen added to give it increased strength and corrosion resistance. Also known as UNS S20910 or ASTM XM-19, this material provides greater corrosion resistance and double the yield strength of 316 stainless steel. 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.

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 similar to 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.
