D2 Tool Steel is has become the tool and die standard to compare against other tool steels. It has relatively high attainable hardness and an abundant and large, chromium-rich alloy carbides in the microstructure. These carbides are what provides very good resistance to wear from sliding contact with other metals and abrasive materials. It is has good toughness, tool performance, price, and a wide variety of product forms. This is also available as an Electro-Slag-Remelted (ESR) product. The remelting process provides improved chemical homogeneity, refinement of carbide size, and the associated improvements in mechanical and fatigue properties.
