Abstract
Commercial wear-resistant steels used in mining are generally categorized by their Brinell hardness. There are few studies comparing the wear resistance of this type of steel within the same hardness category. Considering the above, the objective of this work was to study the behavior of two 400HB commercial sheets of steel against impact-abrasive wear to determine other relevant aspects to consider in the abrasion resistance of this type of alloy. The chemical composition was determined using optical emission spectrometry, while their microstructure was studied using X-ray diffraction, light microscopy, and scanning electron microscopy. The impact-abrasive wear resistance of both materials was evaluated using equipment to determine the Bond abrasion index. Finally, hardness measurements and microhardness profiles were made on the samples tested. The results showed that both alloys could be categorized as low-carbon and low-alloyed steels quenched and tempered. Although hardness was found to be a significant
期刊介绍：
Ingeniare. Revista chilena de ingeniería is published periodically, is printed in three issues per volume annually, publishing original articles by professional and academic authors belonging to public or private organisations, from Chile and the rest of the world, with the purpose of disseminating their experiences in engineering science and technology in the areas of Electronics, Electricity, Computing and Information Sciences, Mechanical, Acoustic, Industrial and Engineering Teaching. The abbreviated title of the journal is Ingeniare. Rev. chil. ing. , which should be used in bibliographies, footnotes and bibliographical references and strips.
