Nitronic 50

Features	Nitronic 50 Stainless Steel is an austenitic stainless steel offering a superior combination of strength and corrosion resistance compared to Stainless Steel 316, 316L, 317, and 317L. It has about double the yield strength at room temperature compared to 316/316L and 317/317L. It maintains good mechanical properties at both elevated and sub-zero temperatures. Nitronic 50 remains non-magnetic even when severely cold worked. It provides excellent corrosion resistance, especially in marine environments. Despite its strength, it can be fabricated using the same equipment and cooling techniques as Stainless Steel 300 series.
Grades Available	XM-19 (UNS S20910), Nitronic 50 Annealed, XM-19HS

Nitronic 60

Features	Nitronic 60 Stainless Steel is an austenitic alloy known for having the best galling resistance among all Stainless Steels. It boasts excellent pitting resistance, outstanding corrosion resistance, and good high-temperature properties at temperatures up to 982°C. It provides superior oxidation resistance and improved crevice corrosion and chloride pitting resistance compared to Stainless Steel 316. Nitronic 60 can be easily formed using common techniques without the need for pre-heating, and can be welded using methods like gas metal arc, gas tungsten arc, and submerged arc. The alloy can be hardened by cold working.
