H13 1.2344 SKD61 hot rolled steel round bar With Diameter 12-150mm

H13 tool steel is air-hardening, hot work 5% chrome tool steel. It combines excellent shock and abrasion resistance with good red hardness making it ideal for use in die casting. Most commonly used in plastic molds and die casting, its ability to withstand rapid cooling from high working temperatures also make it a prime choice for use in extrusion dies. While designed to be a versatile hot work grade, H13 tool steel has been useful in cold work applications as well, particularly when extra toughness is desired but wear resistance is not important.
