Advanced Cold Work Tool Steel

Another exclusive Hitachi metal, SLD-i is an advanced cold work tool steel improving upon AISI D2 steel. Through extensive research and development, Hitachi’s expert metallurgist team brings a superior product to the tool steel array.

Product Summary

SLD-i’s unique composition features small, dense, homogenous carbide distribution, which provide it with the following unique features:

  • Small and isotropic heat treatment deformation
  • Good galling and wear resistance characteristics
  • Higher hardness ratings than that of D2/1.2379

In addition, SLD-i offers minimal dimensional change under heat, as well as shorter lead times and improved production times over standard D2 steel. When the project calls for only the best in cold work tool steel, look no further than SLD-i.
