75CrMoNiW67 is a European chromium-molybdenum-nickel-tungsten alloy tool steel, carried in Germany as DIN 75CrMoNiW6-7 and Werkstoffnummer 1.2762. With roughly 0.70-0.80% carbon and a four-element alloy package — chromium around 1.4-1.6%, nickel and molybdenum each around 0.4-0.8%, and a smaller tungsten addition — this grade is built for high strength combined with solid toughness. The combined chromium-molybdenum content supports good hardenability and secondary hardening response, the nickel adds toughness and impact resistance, and the tungsten contributes fine, stable carbides that help the steel hold hardness under moderate service temperatures.

That balance of high strength, good toughness, and moderate red-hardness makes 75CrMoNiW67 well suited to demanding tooling applications: dies, punches, and structural tooling components that see both high mechanical stress and some thermal loading in service. It is a middle-ground alloy in the broader Ni-Cr-Mo-V/W family of European die steels — more heavily alloyed than a simple oil-hardening grade, but leaner than the highest-nickel deep-hardening die steels, giving a practical combination of strength, toughness, and cost.

75CrMoNiW67's machinability sits between a lean oil-hardening tool steel and a heavily carbide-loaded cold-work grade. The combined chromium-molybdenum-tungsten alloy content is enough to noticeably raise cutting forces over a plain carbon steel, but there is no large primary carbide network the way there is in a D-series grade, so standard carbide tooling handles it without extreme difficulty in the annealed condition (typically 220-250 HB). The nickel addition adds a degree of toughness to the matrix, which can make chip control slightly more demanding than a straight chromium-alloyed steel of similar hardness.

Most tooling in this grade is machined to near-final shape in the annealed state and then hardened and tempered, with finish work done by grinding. Coated carbide grades with good wear resistance and edge toughness are the practical choice for roughing and semi-finishing cuts, and moderate, steady feeds help manage the combined effect of alloy carbides and matrix toughness. Coolant use helps control heat buildup, particularly on deeper cuts where the alloy content raises cutting temperatures faster than a plain carbon steel would.
