Tool Steel Developed for Tough Forming Apps
As there is an increasing number of parts being produced with advanced high-strength steels (AHSS), die makers are being faced with the difficult demands associated with producing tools that can handle these materials in stamping operations.
SLD-i cold work tool steel has been developed to address these demands; the material, according to Diehl Tool Steel (diehlsteel.com), a subsidiary of Hitachi Metals America, the developer of the material, the SLD-i is produced using the same heat treatment as D2 material but exhibits better wear and toughness when used for forming and trim section.
In addition to which, it exhibits better wear than 8 percent Cr steels for specific draw sections of large dies.
Yes, there is a Polestar 1. But it is a hybrid, not an electric vehicle (EV). The Polestar 2 is the company’s first EV—the first of what promises to be many
While aluminum vs. steel is getting more contentious in the world of light-duty trucks, when it comes to creating structures, the heavy-duty truck people know something important about strength and mass.
Anyone who has anything to do with the steel industry ought to go out and buy a Volvo right now.
