STELLITE™ Additive Powder
Las aleaciones Stellite™ basadas en cobalto son nuestras aleaciones más conocidas exitosas, ya que ofrecen las mejores propiedades “integrales”. Combinan una excelente resistencia mecánica al desgaste, especialmente a altas temperaturas, con una buena resistencia a la corrosión. Las aleaciones Stellite™ están principalmente basadas en cobalto con adiciones de Cr, C, W y/o Mo.

NISTELLE™ Additive Powder
Las aleaciones Nistelle™ se han diseñado para resistencia a la corrosión en vez de resistencia al desgaste, particularmente en entornos químicos agresivos donde su alto contenido en cromo y molibdeno proporciona una excelente resistencia a la abrasión. Como clase, también son generalmente resistentes a la oxidación por altas temperaturas y a la corrosión por gas caliente.
