SKD61 Tool Steel bar
Product Overview
SKD61 is a premium hot-work tool steel characterized by its excellent combination of high-temperature strength, toughness, and thermal fatigue resistance. Designed to withstand rapid heating and cooling cycles, SKD61 maintains stable mechanical properties even at elevated temperatures. It is the industry standard for high-pressure die casting and hot extrusion tools, offering a long service life and exceptional resistance to thermal cracking (heat checking).
