Hitachi SLD-i Cold Work Premium Tool Steel Now Available Through Diehl Tool Steel

In specific application areas, customers have experienced a dramatic improvement over conventionally applied D2

Diehl Tool Steel is now offering Hitachi Metals America’s SLD-i cold work premium tool steel, an advanced tool steel grade used in various blanking and forming application where AHSS parts are processed. It is produced using the same heat treatment as D2 but exhibits better wear and toughness when used for forming and trim sections. It also shows better wear than 8% Cr steels for specific draw sections of large automotive dies.

Because of the unique manufacturing process, Hitachi SLD-i also minimizes heat treat deformation, thereby lowering tooling costs. Further comparison between Hitachi SLD-i and D2 reveals that Hitachi SLD-i requires less machining after heat treatment and a decreased amount of shape adjustment than D2. In specific application areas, customers have experienced a dramatic improvement over conventionally applied D2. SLDi is now available in flat cross-sections up to 5 inches thick and provides an effective combination of wear resistance and toughness, tool performance and price. Diehl can machine Hitachi SLD-i tool steel to toolmaker tolerances using its Accu-Square™ process.
