AMS 5766 Nimonic 75 Seamless Nickel Alloy Steel Pipe Procurement Guide

AMS 5766 Nimonic 75 Seamless Nickel Alloy Steel Pipe Procurement Guide
This sourcing guide covers Nimonic 75 (UNS NO6075 / W.Nr. 2.4951 and 2.4630) seamless steel tubing, a nickel-chromium alloy commonly used in high-temperature environments. While AMS 5766 specifically covers alloy 800/800H/800HT bars and forgings, sourcing Nimonic 75 high-temperature steel tubing typically refers to standards such as BS HR 403, DIN 17750-17752, or ASTM B435/B409.
Nimonic 75 seamless tube is an 80/20 nickel-chromium alloy with added titanium and carbon, known for its oxidation resistance and moderate strength at up to 950°C (1740°F).
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.
