Nitronic 50® stainless steel is an austenitic stainless steel with a blend of strength and corrosion resistance that is higher than stainless steel grades 316, 316/316L, 317, and 317/317L .
The high strength, corrosion resistance, and low magnetic permeability of this alloy allows it to be used as a material for medical implants.

Other designations that are equivalent to stainless steel grade NITRONIC® 50 (XM-19) include the following:
Stainless steel grade Nitronic® 50 has machinability characteristics that are similar to other austenitic stainless steels; however it requires slower speeds, more power, and higher rigidity due to its high work hardening rate. It is recommended that coated carbide tooling be used.
Stainless steel grade Nitronic® 50 can be formed using the same methods applied for other austenitic stainless steels. More power for forming and forging is needed for this alloy. Forging can be done at 1177-1204°C (2150-2200°F).
Welding of stainless steel grade Nitronic® 50 can be performed using traditional joining processes. Recommended filler metal should be Nitronic® 50W (AWS E/ER209).
Caution should be taken while using autogenous, high power density joining processes such as EB or laser welding, due to low FN potential and severe outgassing possibility.
Final annealing process performed for several of the applications, is done at 1065°C (1950°F), which is followed by water quenching. In case this material is used in a strongly corrosive environment, annealing should be done at 1121°C (2050°F). This alloy cannot be hardened by heat treatment.
NITRONIC® 50 (XM-19) is widely used in the following sectors:
