Superior Specification 207-2003

When dealing with superior grade H13, the steel making process needs to include secondary refining, either ESR (electro-slag remelting) or VAR (vacuum arc remelting). Additionally the specification calls for improved levels of cleanliness, a reduction in micro and macro banding, and for certification of impact toughness levels at 10ft. lb. average with a 8 ft. lb. single minimum value. This type of manufacturing technique combined with NADCA recommended vacuum austenitizing and pressurized gas quenching can lead to success in production where high volume production or critical performance in the die-casting process is required.
