alloy X-750

alloy X-750 (UNS N07750 / W. Nr. 2.4669 / GH4145 / NiCr15Fe7TiAl) is a precipitation-hardenable nickel-chromium alloy used for its corrosion and oxidation resistance and high strength at temperatures to 1300°F. Although much of the effect of precipitation hardening is lost with increasing temperature over 1300°F, heat-treated material has useful strength up to 1800°F. This kind of alloy also has excellent properties down to cryogenic temperatures. Composition is shown as follows:

Nickel (plus Cobalt): 70.00 min.

Chromium: 14.0-17.0

Iron: 5.0-9.0

Titanium: 2.25-2.75

Aluminum: 0.40-1.00

Niobium (plus Tantalum): 0.70-1.20

Manganese: 1.00 max.

Silicon: 0.50 max.

Sulfur: 0.01 max.

Copper: 0.50 max.

Carbon: 0.08 max.

Cobalt: 1.00 max
