Grade steel, also known as tool steel, is used for the manufacture of tools, gauge components, fixtures and other machine and equipment components. E-Invest offers tool steels characterized by high hardness, low deformability and resistance to high temperatures and overheating. This is a high-quality steel from which metallurgical products are manufactured. In our offer you will find quality steel at excellent, attractive prices. These include:

  • Alloy tool steel for cold work, in the form of round bars, flat bars, square bars and plates;
  • Alloy tool steel for hot work, in the form of round bars;
  • Carbon tool steel – shallow hardening, in the form of round bars, flat bars and sheets;
  • High speed steel, in the form of round bars, flat bars and square bars;
  • Steel for carburizing, in the form of round bars;
  • Nitriding steel, in the form of round bars;
  • Structural alloy steel for refining, in the form of round bars.
