What is NIMONIC 75 material?
NIMONIC 75 alloy is an 80/20 nickel-chromium alloy with added titanium and carbon. This alloy was originally introduced in the 1940s for the manufacture of turbine blades. It is easy to machine and weld, and possesses good corrosion resistance, mechanical properties, and heat resistance.
Nimonic 75 / 80A / 90 Alloy Bar Detailed Information
Nimonic 75 alloy Bar
Nimonic 75 alloy bars, fortified with carbon and titanium, offer exceptional strength and durability in harsh industrial environments. These bars also exhibit excellent machinability, weldability, and oxidation resistance, and withstand high temperatures. Nimonic bars are renowned for their high performance and low-temperature creep resistance. The 75 alloy demonstrates outstanding corrosion resistance, including resistance to pitting, crevice corrosion, and severe stress corrosion cracking.
Nimonic 80A alloy Bar
Nimonic 80A bars are a non-magnetic steel that cannot be heat-treated for quenching but are commonly used in mining and water filtration, often in conjunction with welded or woven screens. We can also supply Nimonic 80 bars in various sizes, grades, and thicknesses at very reasonable prices to meet individual customer needs.
Nimonic 90 alloy Bar
Nimonic 90 round bars are a precipitation-hardening nickel-chromium-cobalt alloy with high tensile strength and creep strength, and a temperature resistance up to approximately 1700 °F (920 °C). NIMONIC 90 bars also exhibit good resistance to high-temperature corrosion and oxidation. NIMONIC 90 alloy bars are widely used in the manufacture of gas turbine blades and discs, hot-working tools, and springs.
