Background/Objectives: This paper presents experimental investigation on the hardness for ASSAB tool steels, XW-5 and XW-42 in heat treatment processes. The experiment was carried out by considering hardening temperature, quenching oil and tempering temperature as parameters at various levels. Methods/Statistical Analysis: The parameters that will influence from the value has been concluded into a Taguchi Orthogonal Array. Findings: The result was analyzed using the Minitab 15 software. Results were compared for XW-5 and XW-42 from the experiment. XW- 42 exhibits the better and harder due to all values are significant. Applications/Improvements: It is observed that different heat treatment processes significantly improves the mechanical properties such as hardness, toughness and microstructure of ASSAB tool steels.
