Nitronic 40 (alloy 21-6-9) is a nitrogen-quenched stainless steel containing high manganese. The initial properties of Nitrided 40 (alloy 21-6-9) are high strength in annealed state, good corrosion resistance at high temperatures, and easy welding and processing. Because these characteristics have been applied in many aviation applications.
  • Nitronic40 / S21900
  • Nitronic40

The austenite of the chromium-nickel-manganese-nitrogen austenitic stainless steel Nitronic40 is very stable. Even after 60% cold working, it can still maintain its non-magnetic characteristics. It has good toughness and corrosion resistance, and its room temperature strength is twice that of general austenitic stainless steel 304, 321, 347, etc. 

The steel not only has good strength and toughness, but also has good manufacturability, corrosion resistance and high temperature oxidation resistance. It has high strength and good toughness at a low temperature of 253°C, and also has good high temperature performance. This steel grade is widely used in aviation and low temperature fields. Although it has high strength, it can still be produced in the same way as ordinary austenitic stainless steel.
