Nitronic 90

Nitronic 90 can be machined after full heat-treatment using conventional machining methods with commercial coolants. Higher speed machining operations (turning, milling, grinding) should be performed using water-based coolants. When boring, drilling or tapping, a heavy lubricant is required. The alloy can be formed using basic conventional techniques.



Applications

Traditionally used in the production of gas turbine blades and hot working tools, Nimonic 90 is also popular in the motorsport and automotive sector. The alloy is useful in applications where high mechanical stress and high temperature is a consideration, including specific engine applications, high-temperature springs and high-performance engine valves. The product is also a preferred choice for extreme high boost pressure turbocharged applications.


Weldability

Solution treated material is suitable for welding, and a post-weld heat treatment is required to achieve optimum results. The alloy can be welded using conventional welding techniques.
