摘要

A PROCEDURE FOR THE ACCELERATED STABILIZATION OF MANUFACTURED PRODUCTS BASED ON QUICK STEELS, essentially characterized in that the temperature rise of the treated piece is determined, very slowly, from the normal to 200º C, maintaining in this calorie the piece for two hours and Gradually it is lowered to 100ºC, keeping it constantly for fifteen or twenty hours and causing a slow cooling until it reaches 0ºC, being a precondition that the piece has been tempered normally according to the types of fast steel, as well as the two corresponding temperings to 590ºC and in the correct tempers, the hardness Ro. it will increase from two to three units and if the hardening has not been sufficiently high the hardness after the third treatment, it will stay the same or, at the maximum, it will rise one unit, getting the piece under this process a greater tenacity when the residual austenite becomes temper in martensite, avoiding fractures due to the perfect diffusion of carbon with steel.
