Features：
ALLOY 713C

Alloy 713C* is a precipitation hardenable, nickel-chromium base cast alloy, which possesses excel-lent strength properties up to 1800 ºF. The alloy has good castability, remarkable resistance to oxidation and thermal fatigue, and outstanding structural stability. It was originally intended to air melt the master alloy and recast the product under argon (air melted, argon cast). With the advent of improved vacuum technology it was found that an increased level of high temperature properties can be consistently attained by vacuum melting the master material and remelting and casting it under vacuum (vacuum melted, vac-uum cast).

Application：

Alloy 713C has found wide acceptance in the superalloy class due to its inherent castability, stability and high level of strength and ductility at elevated temperatures. Some commercial ap- plications for the alloy include vane material and first stage blading in jet aircraft, guide vanes for industrial turbines, and diesel turbocharger wheels. The alloy is included in many experi- mental jet engines and small auxiliary gas turbines and is under evaluation for press forging die,
extrusion die, and die-casting die applications.
