Evaluation of Material Properties and Abrasive Resistance of Tantalum Carbide-Based Hardox Steel for Construction Purpose

In recent days, the demand of high strength and wear resistant steel has been increased. The material properties such as hardness and toughness are plays an important role of wear resistant. In this research, the tantalum carbide-based hardox steel is prepared by stir casting process. To obtain high hardness and toughness, 2, 4, and 6 weighted percentage of tantalum carbide particles are added to the hardox steel. The material properties such as impact strength, tensile strength, yield strength, hardness, percentage of elongation, and density are found on the stir casted steel specimens. The dry sand rubber abrasion apparatus is used to measure the abrasive resistance. In this abrasion test, the various input parameters such as disc speed, types of abrasive, and sliding distance are considered. This modified tantalum carbide-based hardox steel has recommended for civil engineering construction and other applications. The abrasive resistance rate is found by varying the input parameters. The most influential parameter for the abrasive resistance rate is found out through analysis of variance (ANOVA).
