Resumo
Aluminum extrusion dies are an important segment of industrial tools, which are manufactured in steels based on AISI H13. The main properties of steels applied to extrusion dies are: wear resistance, toughness and tempering resistance. The present work discusses the characteristics of a newly developed hot work steel to be used on aluminum extrusion dies. The effects of Cr and Mo contents with respect to tempering resistance, and the Al addition on the nitriding response have been evaluated. From forged steel bars, tests on toughness and characterization via EPMA have been conducted. The proposed contents of Cr, Mo, and Al have attributed to the new VEX grade a much better tempering resistance than H13, as well as, a deeper and harder nitrided layer. Due to the unique characteristics, this new development will provide an interesting alternative to the aluminum extrusion companies to increase their competitiveness.
