DIN 1.2767 Hot Worked Tool Steel
Superior Toughness & Impact Resistance
DIN 1.2767’s high nickel content (3.80-4.30%) ensures exceptional toughness, enabling it to withstand heavy impact loads without cracking. This makes it ideal for forging dies and high-pressure stamping tools subjected to cyclic stress.
Excellent Surface Finish & Polishability
The steel’s fine-grained structure allows for high-gloss polishing, critical for plastic molds requiring mirror-like surfaces. Its low distortion during heat treatment further ensures dimensional accuracy in precision tools.
Adaptability to Extreme Conditions
DIN 1.2767 maintains hardness up to 45 HRC at 650°C, outperforming H13 in thermal fatigue resistance. This thermal stability suits applications like aluminum die-casting and high-temperature extrusion tooling

DIN1.2767(45NiCrMo16) Hot Worked Tool Steel
1.DIN 1.2767 Tool Steel Overview
DIN 1.2767 (X45NiCrMo4) is a high-nickel alloy tool steel renowned for its exceptional toughness, wear resistance, and thermal stability. With a composition of 0.40-0.50% carbon, 3.80-4.30% nickel, and 1.20-1.50% chromium, it achieves a hardness of 52-54 HRC after heat treatment. Its uniform microstructure and deep hardenability make it ideal for large-section tools like plastic injection molds, forging dies, and aerospace components. Widely used in automotive, manufacturing, and heavy machinery industries, DIN 1.2767 balances durability with cost-effectiveness, offering extended tool lifespan under high-stress conditions.
