Comparison of various high-stress wear conditions and wear performance of martensitic steels
Abstract
The martensitic wear resistant steels are typically used in various complex and challenging high-stress wear conditions that commonly include different wear mechanisms. Moreover, the wear resistant steels are not standardized, and the generally used hardness based grading does not truly describe their wear behavior. Thus, versatile application oriented wear testing of the steels as a part of the materials selection process is highly recommended.<br/><br/>In this study, the wear performance of selected wear resistant steels was studied in high-stress abrasion, impact-abrasion, and slurry erosion conditions using three different application oriented wear testing systems and five testing procedures, including the crushing pin-on-disc with hard and soft discs, the impeller-tumbler, and the high-speed slurry-pot with slurry and a dry abrasive bed. In all test methods, large (up to 12.5 mm) crushed granite was used as an abrasive. The wear behavior and the microstructural features of three 500HB hardness grade wear resistant steels and one 600HB grade steel were compared to each other and to a 400HB reference steel. <br/><br/>Although the quite different test procedures ranked the steels quite similarly, as seen in Fig. 1a, there were marked differences between the test methods. In the comparison of the wear testing procedures, the slurry-pot erosion tester produced clearly the highest wear rates (Fig. 1b). However, the crushing pin-on-disc showed the biggest differences between the steel grades, e.g., up to a 58% lower wear rate for the 600HB grade steel compared to the 400HB steel. The differences observed between the 500HB grade steels could not be explained by the variations in the initial bulk hardness values, but the microstructure and hardenability of the steels resulting from the manufacturing processes and chemical compositions had a more marked effect.<br/>
