Nitronic 50 Stainless Steel is an austenitic stainless steel with a blend of strength and
corrosion resistance that is better than Stainless Steel 316, 316L, 317 and 317L. In fact, Nitronic 50
has about double the yield strength at room temperature compared to Stainless Steel 316/316L and 317/317L.
Additionally, Nitronic 50 Stainless Steel has good mechanical properties at elevated and sub-zero s. temperatures.
Another characteristic of Nitronic 50 is that it does not become magnetic even when severely cold worked - unlike
many other austenitic stainless steels. Another advantage of using Nitronic 50 Stainless Steel is its outstanding corrosion
resistance in harsh environments, especially in marine application As noted previously, Nitronic 50 is much stronger
than Stainless Steel 316/316L and 317/317L; however, the same fabrication equipment and procedures used for the Stainless
Steel 300 grades can be utilized for Nitronic 50. In addition, the same cooling techniques used for Stainless
Steel 316/316L and 317/317L can be utilized for Nitronic 50.

Nitronic 60 Stainless Steel is an austenitic alloy, considered to have the best galling resistance of the entire range of Stainless Steels.
Characteristics of Nitronic 60 includeNitronic 60 can be formed using common forming techniques, and pre-heating is not required to weld Nitronic 60. Common welding methods such as gas metal arc, gas tungsten arc and submerged arc can be used to weld Nitronic 60. Hardening Nitronic 60 Stainless Steel calls for the alloy to be cold worked.
