Stellite Stellite 21

When to Choose Stellite 21 Alloy

Stellite 21 is often misunderstood because it does not win the simple hardness comparison. If the only question is which Stellite grade is harder, Stellite 21 is usually not the answer. But many real components do not fail because they need the highest hardness. They fail because corrosion, cavitation, erosion, impact, thermal fatigue, and moderate […]

When to Choose Stellite 12 Over Stellite 6

Stellite 6 is often the first cobalt alloy engineers consider for wear parts, and for good reason. It gives a practical balance of wear resistance, anti-galling behavior, corrosion resistance, hot hardness, and manufacturability. But when the damage on the part is dominated by severe abrasive wear or high contact pressure, Stellite 6 may not be […]

Stellite 6 Welding Rod: Properties, Applications, and Supplier Selection Guide

Stellite 6 welding rod is usually selected when a standard steel filler cannot create the wear-resistant surface an industrial part needs. Buyers and welding engineers use it to build or repair hardfaced layers on valve seats, seal faces, pump parts, sleeves, and other components exposed to sliding wear, abrasion, galling, or elevated temperature. The important […]

Cobalt Alloy Valve Seats for Severe Service Valves: Material, Grades, and Custom Manufacturing Guide

In severe service valves, the valve seat is often the small contact surface that determines whether the entire valve can keep sealing under pressure, temperature swings, solids, and repeated cycling. When that contact band wears, galls, erodes, or loses geometry, leakage starts long before the valve body itself reaches the end of its life. This […]

Stellite 6 Hardfacing for Oil and Gas Valve Seats: Process, Benefits, and Quality Control

Hardfacing Is a Process, Not Just a Material Name Stellite 6 hardfacing is used on oil and gas valve seats because the working surface needs properties the base valve material usually cannot provide alone. The base metal provides structure and pressure support. The Stellite 6 layer protects the sealing face from galling, abrasion, erosion, corrosion-wear, […]
