Apart from this difference, the primary distinguishing factor of higher grade steel such as DH and EH from lower grades such as AH is their toughness. Higher grade steel are tougher than the lower grade ones and toughness decreases as temperature decreases. At lower temperatures, the material will be brittle and can fracture easily at high loading.
