Nitronic is a high strength austenitic steel alloy that was designed for high temperature use. It offers good high temperature properties as well as good low-temperature impact resistance. In addition, Nitronic bolts also offer nearly double the yield strength of 300 series stainless steel. Nitronic fasteners are available in two alloy variations, Nitronic 50 and Nitronic 60, each offering different niche capabilities.

Nimonic Fasteners - Bolts, Screws & Nuts

Nimonic fasteners are best known for their high temperature, low-creep attributes. They are comprised primarily of nickel and chromium – typically more than 50% nickel and 20% chromium – along with other additive such as titanium and aluminum. Due to their ability to withstand extreme temperatures and pressure, they are often used in aircraft parts and gas turbine exhaust applications as well as high temperature furnace applications. Nimonic fasteners are available in two different alloy grades with slightly different capabilities.

Nimonic 75
Nimonic 75 fasteners have good mechanical properties and oxidation resistance at high temperatures to 1200°F (650°C).  Comparable to Inconel 600, Nimonic 75 bolts are primarily used when oxidation and scaling resistance are required in high temperature conditions.
