This catalog and its contents are subject to change without Hot work tool SteelsIsotropy tool Steels are so named becase the difference in mechanical properties between its longitudinal (forging or rolling direction) and transverse directions is reduced, thus overcoming a weak point of ordinarily processed Steels . This technological concept, which is highly evaluated by users of tool Steels , is applied for the production of all our Steels and contributes significantly to stabilizing their characteristics and enhance their service compositions of YSS hot work tool Steels Impurities such as P and S are controlled below the levels specified in JIS by using Hitachi Metals ' own high-qualtity raw composition (%) Toughness of Isoropy LTLTI sotropy DACSKD61 Index of 2mm U-notch Charpy I-ValueHardness 47 HRCL Longitudinal direction T Transverse direction OthersMatrix HSSSKT4 SKD61 free cuttingSKD8 modifiedSKD7 modifiedSKD7 m
