DUFFUS SCOTT, Alejandro B.; CESPEDES INERAITE, Iliana de las Mercedes; GARCIA MATAMOROS, Julio  and  CRUZ CRESPO, Amado. IMPROVEMENT FOR QUALITY CONTROL PROCESS OF STEEL FOR ARMORED THERMAL TREATMENT. cen. az. [online]. 2019, vol.46, n.2, pp. 63-70.  Epub June 01, 2019. ISSN 2223-4861.

The thermal treatment like a technological process requires a quality control system before, during and after his execution. The properties to be controlled in each moment depend fundamentally on the specific element or piece. In present work the quality control of thermal treatment to steel sheets for armored 30XΓCA, with 200 x 200 x 8 mm and 6 mm dimensions is approached. A coherent and systematic description of actions to be taken before (inspection and testing of the steels), during (control of the process) and after (inspection and final test) in control of thermal treatment process is made. A flow chart of the steps to follow for the execution of the control process is presented. The hardening curve of the 30XΓCA steel is determined by the Jominy test and the technology charts for thermal treatment are improved.

Keywords : Steel for armored; System for the control of quality; hardenability; heat treatment.
