Nimonic 91 Spring Wire High Temperature Alloy With UNS N07090 And W. Nr. 2.4632.

Introduction:

In the composition of Nimonic91, nickel element is the main component, the addition of nickel element improves the corrosion resistance and high temperature strength of the alloy. Chromium helps to enhance the oxidation resistance of the alloy, while cobalt can improve the hardness and red hardness of the alloy. The titanium element helps to refine the microstructure of the alloy and improve the strength and toughness of the alloy.

The high temperature performance of Nimonic91 is mainly due to its special structure. At high temperatures, the crystal structure of Nimonic91 becomes more stable, which improves its high temperature strength and creep resistance. In addition, Nimonic91 also has good fatigue resistance and corrosion resistance, which enables it to be used in harsh environments for a long time.
