N50 Stainless steel is an austenitic stainless steel grade having high yield strength as compared to stainless steel 304 and 316. Moreover, Nitronic 50 has excellent mechanical properties at both elevated and sub-zero temperatures. UNS S20910 stainless steel is known for outperforming other stainless steel grades at low cost. Nitronic 50 Stainless Steel is incredibly versatile, durable and stable in many diverse environments and has better corrosion resistant properties than 317L stainless steel.

The high strength, corrosion resistance, and low magnetic permeability of XM-19 allow it to be used as a material for medical implants.  XM-19 can be a confusing austenitic steel to work with, as there are three different types of conditions used for numerous applications. The three conditions are annealed as-rolled and high strength. As-rolled is a term used by the mill to state the fact that it is a “rolled” material. All conditions of XM-19 are first rolled. Both the annealed condition and the as-rolled condition are rolled at the same temperature. To acquire XM-19 annealed, the material would first be rolled, followed by either a mill or local annealing process which lowers the tensile and yield properties resulting in a more workable material. On the other hand, transforming XM-19 into the high strength condition can only be done at the mill after the original rolling process, which is done at a lower temperature than annealed and as-rolled material to further help increase the properties. Then high strength material is rolled a second time and later cold worked, which again increases the physical properties of the material even more.
