ENGINEERING STEELS + ALLOYS

H13 Tool Steel (X40CrMoV5-1)

H13 toolsteel exhibits high strength at elevated temperatures, it also has high hot wear resistance, good toughness, thermal conductivity and resistant to hot cracking, limited water cooling possible. Applications: Standard material for hot forming tools, extrusion tools, forging dies, pressure casting tools, hot shear knives, tools for plastic industry. Also available in EFS and ESR condition where better properties are required.
