AISI Type H13 Hot Work Tool Steel
Categories:	Metal; Ferrous Metal; Tool Steel; Hot Work Steel
Material Notes:	High hardenability, excellent wear resistance and hot toughness. H13 has good thermal shock resistance and will tolerate some water cooling in service. Nitriding improves hardness, but can diminish shock resistance if hardened layer is too thick. Electroslag Remelted (ESR) H13 has greater homogeneity and an exceptionally fine structure, resulting in improved machinability, polishability and high temperature tensile strength. Applications: hot work applications: pressure die casting tools, extrusion tools, forging dies, hot shear blades, stamping dies, plastic molds. ESR H13 is great for aluminum die-casting tools and plastic mold tools requiring a very high polish. Weldability: Pre and Post-heating recommended, can be welded with oxy-acetylene, inert shielded gas and shielded metal arc; Filler should be similar to the base metal.
