Deep Dive into DIN 1.2379 Steel: Composition, Equivalents, and Alternatives

To make the most informed material selection, a thorough understanding of DIN 1.2379’s metallurgical characteristics, its equivalent grades, and potential alternatives is crucial.

Chemical Composition of DIN 1.2379 Steel (Approximate Weight %):

The unique performance attributes of DIN 1.2379 Steel are directly attributable to its precise chemical composition. While minor variations may exist between different manufacturers, the typical elemental breakdown is as follows:

• Carbon (C): 1.45 – 1.60% (Crucial for high hardness and forming a large volume of primary carbides, which provide exceptional wear resistance.)
• Silicon (Si): 0.20 – 0.50% (Deoxidizer; contributes to steel’s strength and elasticity.)
• Manganese (Mn): 0.20 – 0.50% (Improves hardenability and hot workability.)
• Chromium (Cr): 11.00 – 13.00% (Forms highly stable and hard chromium carbides, which are the primary source of its extreme wear resistance. Also contributes to a degree of corrosion resistance.)
• Molybdenum (Mo): 0.70 – 1.00% (Enhances hardenability, improves temper resistance, and reduces temper brittleness, contributing to overall toughness.)
• Vanadium (V): 0.70 – 1.00% (Forms fine vanadium carbides, which further refine grain size, enhance wear resistance, and maintain hardness at elevated temperatures.)
• Sulfur (S): Max 0.030% (Maintained at low levels to prevent hot shortens and maintain ductility/toughness.)
• Phosphorus (P): Max 0.030% (Kept low to minimize brittleness.)

Equivalent Grades to DIN 1.2379:

Understanding equivalent grades facilitates global sourcing and compliance with various international specifications.

• AISI D2 (USA): This is the most widely recognized and functionally identical equivalent, sharing virtually the same chemical composition and performance characteristics.
• JIS SKD11 (Japan): Another very close equivalent, frequently used in Asian markets, with similar applications and properties.
• X153CrMoV12 (EN ISO 4957 / W. Nr. 1.2379): This is the European standard designation for this high-carbon, high-chromium cold work tool steel.
• GB Cr12MoV (China): The Chinese equivalent, also mirroring the exceptional wear resistance and dimensional stability of D2.
• BS BD2 (UK): The British Standard equivalent for D2 steel.
• SS 2310 (Sweden): Swedish standard designation.

Alternative Grades to DIN 1.2379:

While DIN 1.2379 excels in many applications, specific project requirements might necessitate considering alternative tool steel grades with different property balances.

• DIN 1.2080 (X210Cr12 / AISI D3): This is an older, simpler high-carbon, high-chromium steel (like D2 but without Mo and V). It offers very high wear resistance but can be more brittle and has lower toughness compared to 1.2379. It also has less dimensional stability during heat treatment. Suitable for very high wear applications where some brittleness is acceptable.
• DIN 1.2842 (90MnCrV8 / AISI O2): A general-purpose oil-hardening cold work tool steel. It offers good toughness and dimensional stability but significantly lower wear resistance compared to 1.2379. Suitable for simpler dies and tools where wear is not extreme.
• DIN 1.2601 (X160CrMoV12 / AISI D4): A modification of D2, often with higher carbon and vanadium, potentially offering even greater wear resistance but possibly at the cost of some toughness. Used for extremely abrasive applications.
• High-Speed Steels (e.g., AISI M2 / DIN 1.3343): If the application involves higher operating temperatures and requires hot hardness in addition to wear resistance (e.g., some cutting tools where friction generates significant heat), high-speed steels might be considered. However, they are generally more expensive and have different heat treatment requirements.
• Powder Metallurgy (PM) Tool Steels (e.g., CPM 10V, Vanadis 8): For applications demanding truly exceptional wear resistance and toughness that exceed the capabilities of conventional D2, PM steels are an option. These steels have a more uniform carbide distribution and finer grain structure, leading to superior performance, but come at a higher cost.

The selection of an alternative grade hinges on a detailed assessment of the application’s specific demands, including anticipated wear, required toughness, operating temperature, and budgetary constraints. Our technical experts at Milano Special Steel possess the knowledge to guide you through this selection process, ensuring you choose the optimal material for your success.
