Análisis de Desgaste Abrasivo en Acero AISI SAE H13

Abstract

At present there are no direct studies and they indicate in a concise way the values ​​that some steels have against the phenomenon of abrasion or abrasive wear. In the present work we seek to obtain reference data on the abrasive wear resistance of hot tool steel, AISI H13 STEEL. This was followed by procedure B established by the ASTM G65 standard, which governs everything related to the realization of this type of wear. Three samples of the material with the measures established within the norm were taken, carrying out the tests with a duration of a little more than 12 minutes each one. Metallographic preparation of this material was also performed to analyze its microstructure (ASTM E3), microhardness (ASTM E384) and hardness (ASTM E18). As a result, a series of carbides in spheroidal form embedded in a ferritic matrix, the microstructure of a ferritic material annealed at a temperature lower than the eutectoid, was found in the microstructural analysis of the material, giving a material with a hardness that this case was Of 87 HRB. As for the abrasive wear, the results indicated an average volume loss of 72.86 mm3, images were also obtained by means of scanning electron microscopy, in which uniform wear is evidenced without major damages to the material, confirms one of the main Advantages of the AISI H13 steel and its high resistance to abrasion.
