Advanced Vacuum Melting & Casting

At Shiney Steel, we utilize advanced Vacuum Induction Melting (VIM) and precision vacuum casting technologies to produce high-purity nickel-based superalloy master alloys. Our vacuum melting and casting capabilities are purpose-built for the aerospace, gas turbine, power generation, turbocharger, and investment casting industries – delivering reliable quality, batch-to-batch consistency, and superior metallurgical cleanliness.

Why Vacuum Casting?

Vacuum casting is a highly specialized process essential for manufacturing high-performance nickel-based superalloys. By melting and pouring under high-vacuum conditions, the process effectively eliminates contamination from oxygen, nitrogen, and hydrogen – preventing oxidation of reactive elements such as aluminum and titanium. The result is:

Superior metallurgical cleanliness– minimal non-metallic inclusions
Precise chemical composition control– tight elemental tolerances
Enhanced microstructural uniformity– consistent grain structure and γ′ precipitation
Improved mechanical properties– optimized creep, tensile, and fatigue performance

Applications for Nickel-Based Metal Castings

While nickel-based metal castings are used by dozens of different industries, they find their home in a handful of applications that utilize their heat resistance effectively. Bescast specializes in applied nickel-based castings for the aerospace and energy sectors. We design and engineer products and prototypes for clients that include nickel-based metal castings for the following components:

Turbine Blades and Vanes
Structural Castings
Open and Closed-Face Impellers
Heat Exchangers
Exhaust Systems
Furnaces
