Nitronic 50 (XM-19) High Strength Stainless SteelBest Stainless supplies high-quality Nitronic™ 50 high-strength stainless steel. Nitronic™ 50 stainless steel is an austenitic grade providing corrosion resistance greater than other typical austenitic grades such as SS 316/316L and 317/317L. It is also capable of nearly double the yield strength of similar austenitic grades. Nitronic™ 50 (XM-19) stainless steel offers yield strength three times that of 316. Our inventory of stock shapes includes Nitronic 50 round bar and pump shaft quality bar in addition to a selection of Nitronic 50 flat and hex bar.

Our Nitronic 50 stainless steel bar comes in a range of grades and shapes used for many applications. We have an extensive stock of shapes including Nitronic 50 stainless steel round barhex barflat bar, and square bar, as well as boat shaft and pump shaft.

Nitronic® 50 (XM-19) Stainless Steel Bar Characteristics

The Nitronic® 50 stainless steel can maintain performance with intermittent exposure to temperatures up to 2050° F, making it useful for automotive valves and other potentially high-heat situations. 

Nitronic® 50 is highly resistant to corrosion over other materials around the same price point, with a resistance nearly double the yield strength of that of 316 stainless steel. High-strength Nitronic® 50 has low magnetic permeability and can withstand high-temperature environments. Additionally, it offers sulfide resistance along with excellent corrosion resistance, making it durable for applications in the chemical or oil & gas industries.
