OK TIGROD 13.32 (ER80S-B6)
El OK Tigrod 13.32 es una varilla de acero de baja aleación, del tipo 5% Cr, 0,5% Mo, revestida de cobre, para el soldeo TIG (GTAW) de materiales de composición similar. El OK Tigrod 13.32 se utiliza normalmente con Ar puro como gas protector. Aunque los valores mínimos de las propiedades mecánicas se obtienen directamente tras el soldeo, la unión debe someterse a tratamiento térmico posterior.
