Stellite Casting Service

Stellite 1 is a cobalt-chromium alloy with excellent hardness and superior wear resistance, making it ideal for abrasive and high-impact tasks. It performs well under intense heat and friction, holding its shape and edge when other materials degrade.

Through Stellite casting, you can create durable parts like extrusion dies, mining drill bits, and industrial cutting knives. Though difficult to machine, this alloy is perfect when you need long-lasting components for extreme environments. Its consistent strength at high temperatures helps reduce part failures in critical operations.

Stellite 6B is a toughened, machinable version of Stellite 6, engineered for applications requiring impact resistance and smoother surfaces. It’s especially useful for bearing sleeves, diesel engine valve guides, and cam followers. Produced through Stellite casting, this alloy resists seizing, galling, and surface damage under extreme stress.

Its toughness means less downtime and fewer part replacements. Unlike cast-only grades, 6B allows you to finish parts with more flexibility. If you're working with components that take repeated loads or impacts, this material keeps your equipment running smoothly and reliably.

UNS R30016

Stellite 12 provides high hardness with moderate impact resistance, making it ideal for sliding and cutting parts exposed to pressure and edge wear. You will want it for extrusion rollers, gate valve seats, and cutting blades. It holds its sharpness and shape under repetitive stress, making your equipment more durable.

Stellite 12 is an excellent choice when parts need to resist chipping, deformation, or heat damage over time. It is also weldable and maintains strong metallurgical properties in high-friction or thermally stressed applications.

UNS R30012

Stellite 20 is a corrosion-resistant alloy developed for use in chemically aggressive environments. It is ideal for pump impellers, agitator shafts, and reactor valve internals. This grade stands up to solvents, acids, and chlorides, where other materials would weaken or corrode. It also offers good strength retention at elevated temperatures.

You should consider it for chemical plants, marine systems, or pharmaceutical facilities that require stable and long-lasting parts. Stellite 20 helps reduce equipment failures and keeps operations clean and uninterrupted.

Other Designation
UNS R30605

Stellite 21 offers exceptional toughness, corrosion resistance, and thermal fatigue strength, making it suitable for critical aerospace, nuclear, and medical applications. It performs reliably in turbine vanes, orthopedic implants, and high-temperature valves. Stellite casting allows you to create complex, high-performance parts that maintain integrity under extreme thermal cycling.

The alloy resists cracking and distortion, and its biocompatibility makes it ideal for medical systems. You will appreciate its easy weldability, strong surface integrity, and stability in both oxidizing and reducing environments, making it perfect for long-term use where precision and safety are essential.
