Fabrication and Heat Treatment
Machinability
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.
Forming
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
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.
Heat Treatment
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.
