Alloy Digest (2014) 63 (8): Ni-716.
Published: 01 August 2014
... Alloy 740H (see Alloy Digest Ni-613, September 2003) is a precipitation-hardenable Ni-Cr-Co alloy containing molybdenum and niobium. The primary application for the alloy is boiler tubes for advanced ultra-supercritical steam boilers. This data sheet covers a modification of that alloy to correct...
