Principal tool steels
| A-2 | Punching tool (punch and matrices) blades for shears, high tenacity, excellent stability to heat treatment. Nitruding is possible. | | A-7 | Air hardening steel extremely resistant to abrasion. Moderate temperature of hardening, low distortion, good resistance to high temperature. Uses: moulds for abrasive, ceramic grinding stones and components for jet sanding machines. | | D-2 | High tenacity steel (punch and matrices), blades for shears for wood, tool to roll nets, tools of stamping and spinning, stamping tools for ceramic and the pharmaceutical industry. | | H-13 | Tools hot working and forming, extrusion matrices of die casting, matrices of forging mill, plastic matrices, blades for shear for extra services (cold or hot). | | T-1 | Turning tools, tool planers, drills, threading tools, cutters. Components of matrices injection of zinc. | | O-1 | Cutting tool (punches and matrices), threading tools, wood tools, mechanical knives for wood industries, paper and metallurgic industries, measurement gauges. | | P-20 | Steel for injection mold, easily used and polished. Can be textured (electrochemical engraving) | | S-1 | Cutting tool (punches and matrices) for strong plates, cold punching, cold shearing tool, stamping tool, tool for hot working at relatively low temperature. | | S-7 | Excellent balance of tenacity and wear, blades of shear and punching, hot working at moderate temperature. | | W-1 | Threading tools, wood tools, cold punching, stamping tools. |
