Abstract

A method for producing porous billets for use in the production of high alloy steel with satisfactory hardening strength and high hot hardness, in which a high alloy steel powder containing alloying elements including at least one element is used with a strong affinity for oxygen, in which: (see formula), where ctot is the carbon content of the powder in% by weight, cesteq is the carbon content that would be stoichiometrically necessary to form carbides with the alloying elements, in% by weight, cesteq is the total oxygen content of the powder in% by weight, and k1 are constants that can acquire values between 0.7 and 1.0; which comprise heating the powder in a vacuum at a temperature of 900-125º c, at a pressure that at the beginning and at the end of the treatment is less than 10-1 torr, for a time sufficiently long for the total oxygen content to fall below 0.05% by weight, after heating.
