CAST INGOT
Cast ingot superalloys, engineered for critical applications.
SeAH Superalloy Technologies produces high-purity nickel- and cobalt-base ingot superalloys, engineered for the most demanding applications on earth and beyond.
OUR APPROACH
Advanced chemistries.
Built for the foundry.
From our Temple, Texas facility, we supply investment casting teams with cast ingot superalloys that perform when temperatures spike, stresses climb, and failure is not an option. From first qualification heats through full-rate production, we are a customer-first, production-focused partner for high-purity cast ingots and high-output programs.
FEATURED PRODUCTS
Proven superalloys, qualified for production.
Our nickel-base superalloy powders are engineered for pushing performance boundaries.
CAPABILITIES
Innovation minded.
Production focused.
Production
Built for capacity at scale.
Our ingot operations are built for high-volume production, with vacuum induction melting (VIM) systems dedicated to nickel- and cobalt-base chemistries and lot sizes up to 7 tons. Tight compositional control delivers melt-to-melt consistency you can qualify against, across the workhorse chemistries that power aerospace, industrial gas turbines, and other demanding applications.
Capacity
3.5 ton (7,000 lbs) and 7 ton (14,000 lbs)
Standard Ingot Diameters
2-7/8", 3-1/2", 4", 5", 6", 7"
Ingot Bar Length
42" nominal, with incremental cutting available
Surface Finish
Fully ground
Marking
Laser etched for full traceability from heat to part
QUALITY
Casting excellence is the standard.
Behind every heat is deep metallurgical expertise and a fully accredited testing laboratory. We qualify ingots to leading AMS, ASTM, and ISO specifications, the same standards that govern the most critical hardware flying today. This framework gives customers confidence to move from initial qualification heats to serial production with fewer surprises and shorter cycles.
Chemistry
Full elemental analysis and conformance to AMS, ASTM, ISO
Microstructure
Grain size, inclusion rating, and metallographic evaluation
Traceability
Full documentation from heat to certification

AUTOMATION
Traceability. Repeatability.
Consistency.
Our VIM systems use real-time digital monitoring and closed-loop control of pour rate, temperature, and melt parameters, with sensor feedback to minimize heat-to-heat variability.
A controlled workflow tracks every ingot from intake through casting, with digital records supporting traceability, root-cause analysis, and process improvement. In-house lab data feeds directly into melt controls, keeping chemistry locked and quality stable as programs scale.

01
What industries does SeAH serve?
We serve the most demanding applications in aerospace, industrial gas turbines, power generation, military and defense, and space exploration.
02
What ingot formats and cutting options does SeAH offer?
SeAH produces vacuum induction melted (VIM) cast ingots in diameters ranging from 2-7/8 to 7 inches and nominal lengths up to 42 inches. Incremental cut-to-length options are available to meet customer specifications, improve material utilization, and support efficient downstream processing.
03
Where are SeAH’s production and engineering facilities located?
Our production facility is in Temple, Texas, in the heart of Central Texas and about an hour north of Austin. The location puts us in one of the country's fastest-growing regions, with strong access to talent, logistics, and the expanding industrial corridor along I-35.
04
What makes SeAH’s superalloys unique?
Our ingots are produced via vacuum induction melting with rigorous chemistry control, delivering the purity, homogeneity, and lot-to-lot consistency that rotating and static components require. When the application can't tolerate variation, neither can we.
