Special AlloysBar/Rod
Description (English)
NIMONIC Alloy 75 is supplied in bar hot rolled annealed condition, delivering yield strength of 351 MPa, tensile strength of 800 MPa, elongation of 44%, and hardness of HRB 87. The alloy maintains its mechanical properties and oxidation resistance at elevated temperatures, making it suitable for components in industrial heating, chemical processing, and aerospace auxiliary systems. The high chromium content (Cr 20.5) provides excellent resistance to oxidation, sulfidation, and carburization in high-temperature environments. The alloy is readily fabricated by hot and cold working and can be welded using standard techniques.
