Nitronic® is a trade name referring to a specific group of nitrogen-enhanced super duplex stainless steels. Nitronic® was first developed by Armco Steel; however, since the 2000s the trademark has belonged to AK Steel Inc. The term nitronic® refers to the way in which nitrogen has been used to increase the strength of the steel. Unlike other kinds of nitrogen-enhanced steel, nitronic® is notable as the nitrogen has been added internally
This trademark covers a family of more highly alloyed austenitic stainless steels. Such is the recognition of the trademark that it is generically used to describe such alloys even if produced by another manufacturer. The most widely used Nitronic® alloys are Nitronic® 50 (Fermonic 50, XM19, UNS S20910, 1.3964) and Nitronic® 60 (Fermonic 60, UNS S21800).
Nitronic® 40 was the first kind of nitronic® developed. It is commonly used in the aerospace industry, where its high performance at ultralow temperatures makes it a good choice for hydraulic tubing.
Nitronic® 50 is a super austenitic stainless steel, offering improved strength and significantly improved corrosion performance (PREN = 34) over regular 3xx series grades. It is most widely used in the production of valve stems due to its toughness at lower operating temperatures, and also in a wide range of marine and boat hardware due to its ease of fabrication.
Nitronic® 60 is specifically formulated to achieve excellent galling and wear resistance and is used in applications such as connectors. Nitronic® 60, as well as Gall-Tough Alloy, was designed to offer resistance to galling – a form of wear caused by adhesion between sliding surfaces and metal-to-metal wear.
Langley Alloys carries a wide-range of high strength austenitic stainless steels, including numerous Nitronic® alloys.
