Experimental & Numerical Analysis of Steel Grades for Wear Resistance

Abstract

This work examines the process of abrasive wear resistance of porous AISI D2 and H13 tool steels using Dry Sand Rubber Wheel (DSRW) tester for abrasion by the ASTM G65 standards. Different samples of hardness were subjected to various loads to check the wear performance. Findings show that D2 tool steel has superior wear resistance as compared to H13; due to its higher carbide content. The hardness was changed from 8 HRC to 62 HRC to formulate the D2 alloy for D2. The volume loss reduced significantly from 137.87 mm ³ to 58 mm ³ for the respective hardness which showed better wear resistance. In the same way, the specific wear rate of D2 reduced from 0.000246 mm³/N-m to 0.0001 mm³/N-m. By contrast, H13 steel exhibited increased volume loss on the rise of loading with specific wear rates that ranged between 0.000471 mm³/N-m and 0.000519 mm³/N-m. These results substantiate the fact that hardness is vitally important for wear resistance especially in case of D2 steel which makes it a better option for those applications that need high wear resistance in terms of abrasion.
