Vacuum Induction Melting – Inert Gas Atomization process is used to manufacture STL-21 powder at various fractions. Our unique controls in process will control particle size and morphology to get good powder flowability for achieving dense coatings consistently. STL 21 is a cobalt-chromium-tungsten superalloy having excellent resistance to cavitation, galling, wear and corrosion in both oxidizing and reducing atmosphere. It is used in petrochemical, power generations and medical applications.
