Featuring excellent creep resistance, anti-oxidation properties, and strong surface stability, superalloys are a necessity for today's high temperature industrial applications. Our inventory of superalloys includes duplex alloys, hastelloys, nickel based, nickel-chromium, cobalt based, and proprietary combination alloys.
We specialize in highly repeatable short production runs of superalloy investment castings in the 0 to 20 lbs range, and can produce 100+ lbs castings when required, as well as:
- Reduction or elimination of high machining costs associated with superalloys
- Intricate, near-net shape parts achievable without machining
- Easily convert multiple parts into single assemblies
- Thin walls for weight reduction opportunities
- Surface texture of 125 RMS or better
- Tolerances within +/- .005 inches per linear inch
- Highly complex dimensional geometry
From concept to completion, PCT ensures that superalloy investment castings meet the form, fit, and function of your design.
Form – Unique Superalloy Casting physical characteristics
Today's fourth generation of superalloys can withstand temperatures well over 2000° F, and feature chemically engineered grain structures for increased hardness. Superalloys are precipitation strengthened to remove crystal impurities, further enhancing mechanical properties by removing stress anomalies.
While superalloy mechanical properties vary by grade and type, common characteristics include high levels of heat resistance, abrasion resistance, anti-oxidation, and corrosion resistance.
Fit – How we make Superalloy Castings work for you
The hardness of superalloys make them difficult to machine. Our Netshape, as-cast parts reduce or eliminate the majority of costly machining, while still maintaining precision tolerances within +/- .005 inches per linear inch.
Precision Castings of Tennessee automates the majority of the superalloy casting process, ensuring we produce consistent results that save our customers money. Casting superalloys is a somewhat delicate process that requires constant monitoring, and is highly susceptible to cracking when performed by untrained foundries.
Function – Real world Superalloy casting examples
Superalloy's ability to operate at higher temperatures provides greater opportunity for efficiency and extended component life over typical alloys. High temperature applications, such as aerospace and power generation turbines, absolutely require the unique mechanical properties of superalloys.
