H-13 ESR Mold Steel Data Sheet

Common Tradenames: Orvar® Supreme, Nu-Die XL

H-13 ESR is a premium version of H-13 melted by the electroslag remelt process. This process provides a more uniform and cleaner microstructure. These characteristics provide the user with better transverse toughness, polishibility and more resistance to thermal fatigue, which are especially important in die casting dies, plastic molds and extrusion tools. H-13 ESR may be used for tool temperatures up to about 1000 F, with brief exposures up to 1100 F.
