Abstract

Procedimiento para la fabricación de tuberías con tratamiento térmico para su homogeneización, efectuándose la fabricación de aleación de acero de cromo el níquel, caracterizado porque comprendo las rasas de forjar un paquete ó lingote del metal, de formar en sentido longitudinal un agujero en el mencionado paquete de metal de extrusionar el paquete de metal para constituir una concavidad tubular, de trabajar ó laminar la concavidad tubular en frío para formar un producto intermedio de un largo de manos de 7,5 metros, aproximadamente y de homogeneizar el referido producto intermedio para llevar a efecto la estabilización del carbono y la difusión de cromo por someter el producto intermedio trabajado en frío, a dos sucesivos recocidos isotérmicos.
