Nitronic nuts are composed of an alloy called Nitronic 60 (XM-19). This alloy consists primarily of chromium and nickel, with the addition of manganese, nitrogen, and sulfur to improve corrosion resistance, which also incorporates the ability to be cold-worked and hold excellent strength. Additionally, silicon and copper are incorporated for better oxidation resistance and improved high-temperature strength. The balanced chemical composition of Nitronic 60 gives it a combination of significant properties such as good fatigue resistance, excellent corrosion resistance, low coefficient of friction, low galling tendencies and weldability. As a result, this type of nut is often used in environments with heavy use or frequent cleaning requirements due to its durability.
Nitronic nuts are precision parts used in diverse industries due to their excellent physical and mechanical properties. These high-strength nuts are produced from an austenitic stainless steel alloy and possess a substantial corrosion-resistant capacity. Nitronic nuts can withstand temperatures up to 1000°C to 1150°C and have a 150,000 psi ultimate tensile strength, making them durable under demanding operating conditions. Their elongation characteristics also make them ideal components for shock-loaded applications, while their unmatched galling resistance is suitable for both low and high-cycle fatigue operations. Additionally, the design of these components ensures dynamic loading capabilities, along with a much-increased torque tolerance compared to other types of fasteners.
These nitronic nuts are manufactured per the standards established by authorities like DIN, MSS, ANSI, and ASTM. While nuts of other metals or alloys usually corrode in water, nitronic alloy remains resilient, making them ideal for marine application. These nitronic nuts undergo vigorous testing under diverse conditions to ensure that the nuts are of excellent quality and strength.
