Stellite-12
STL-12 is a cobalt-based Stellite-12 alloy for thermal spray, resistant to wear and hot oxidation, ideal for industry, aeronautics and energy with coatings for rollers, matrices and exhaust systems.
Usage
Wear, High temperature
Functional property (technical details)
Wear-resisting, Resistant to hot oxidation
Typical applications
Coatings for rolls and matrices in the treatment of hot metals or the glass industry, for resistance to thermal wear and friction.Repair of substrates in exhaust systems or turbines, where stability reduces degradation in oxidative environments.
Key benefits
Good sphericity, high fluidity, particle size homogeneity, low oxidation
