Inconel X750 Ni-Cr Alloy Welding Wire
Inconel X750 Ni-Cr Alloy Welding Wire Introduction
Inconel X750 is a precipitation-hardening alloy that is highly resistant to corrosion and oxidation. It has good stress-rupture strength and low creep rates under high stress at temperatures up to 1500ºF (815ºC) after appropriate heat treatments. It is widely used in Oil & Gas Extraction and Processing, Nuclear, Aerospace, Power Generation and Automotive.
Inconel X750 is a Nickel-Chromium alloy made of precipitation hardenable by additions of Al and Ti, having creep-rupture strength at high temperatures to about 700oC (1290oF). It is widely used for high-temperature conditions but is not as strong as Nimonic 90.
Alloy X-750 has excellent resistance to chloride ion stress-corrosion cracking. It exhibits satisfactory resistance to numerous oxidizing environments. The alloy has similar corrosion resistance to alloy 600 in many media.
Inconel X750 is also known as Nicrofer 7016, Superimphy 750, Haynes X750, Pyromet X750, and Udimet X750.
