Mechanical Isotropies
Cast and sheeted materials, such as tool steels, show different properties in rolling direction and transverse direction, especially regarding resistance and toughness.
Transverse direction properties are generally inferior to longitudinal properties.
The smaller the difference, the better the steel’s isotropy.
This property, practically independent of chemical composition, depends on factors within the steel manufacturing process.
Electroslag remelting (ESR or SUPRA) substantially improves this isotropy, and pulvimetallurgic steels, made by TSP (Tool Steel Process) show remarkably high mechanical isotropy.
