Industeel TENASTEEL® Cold Work Tool Steel Product Information -:- For detailed product information, please contact sales. -: # **Industeel TENASTEEL® Cold Work Tool Steel** ## **Product Overview** Industeel TENASTEEL® represents a premium range of cold work tool steels specifically engineered for applications requiring exceptional wear resistance, high compressive strength, and dimensional stability under load. These steels are characterized by their advanced metallurgical purity, homogeneous microstructure, and optimized heat treatment response. TENASTEEL® grades are produced through state-of-the-art secondary refining processes (such as Electro-Slag Remelting - ESR or Vacuum Arc Remelting - VAR) to ensure minimal segregation, uniform carbide distribution, and superior isotropy of properties. This results in tools with longer service life, consistent performance, and reduced risk of premature failure in demanding cold forming operations. ## **Key Features & Benefits** * **Superior Microstructural Purity:** Advanced melting technologies (ESR/VAR) drastically reduce non-metallic inclusions and eliminate macro-segregation. This enhances polishability, etching quality, and fatigue resistance. * **Excellent Wear Resistance:** High carbon and carbide-forming alloy content (Cr, Mo, V) leads to the formation of hard, fine carbides that provide outstanding resistance to abrasive wear, galling, and adhesive wear. * **High Compressive Strength & Hardness:** Capable of achieving very high hardness levels (up to 64+ HRC), enabling tools to withstand extreme pressures without deformation or indentation. * **Good Toughness:** Balanced chemistry and clean steelmaking provide relatively good toughness for their hardness class, reducing susceptibility to chipping and cracking. * **Superior Dimensional Stability:** Low distortion during heat treatment due to high hardenability and homogeneous structure, critical for precision tools. * **Enhanced Grindability & Machinability (Annealed State):** Supplied in a spheroidized annealed condition for safe and efficient machining of complex tool geometries. ## **Product Range & International Standards** The TENASTEEL® family includes several classic cold work steel grades, each with specific characteristics. Below are the most prominent ones with their international equivalents: | Industeel Grade | Common Designation | Intl. Standards (Equivalent) | Key Characteristic | | :--- | :--- | :--- | :--- | | **TENASTEEL® A8** | **D2** | **EUR (EN): 1.2379 / USA (AISI): D2 / JIS: SKD11** | **High-Carbon, High-Chromium.** The benchmark for wear resistance. Excellent for blanking, forming, and long-run dies. | | **TENASTEEL® O2** | **O1** | **EUR (EN): 1.2510 / USA (AISI): O1 / JIS: SKS3** | **Oil-Hardening, Non-Shrink.** Good all-round grade with low distortion, easy to heat treat. Good machinability. | | **TENASTEEL® A2** | **A2** | **EUR (EN): 1.2363 / USA (AISI): A2 / JIS: SKD12** | **Air-Hardening, Medium-Alloy.** Compromise between wear resistance (D2) and toughness (O1). Good dimensional stability. | | **TENASTEEL® D6** | **D6** | **EUR (EN): 1.2436 / USA (AISI): D6** | Similar to D2 with higher carbon, offering extreme wear resistance for severe abrasive applications. | *Note: TENASTEEL® is Industeel's trademark for its high-quality, specially melted tool steel range. Specific grades may be offered with different levels of refinement (e.g., ESR).* ## **Typical Chemical Composition (Example Grades - %)** | Element | TENASTEEL® A8 (1.2379 / D2) | TENASTEEL® O2 (1.2510 / O1) | TENASTEEL® A2 (1.2363 / A2) | | :--- | :--- | :--- | :--- | | **Carbon (C)** | 1.50 - 1.60 | 0.90 - 1.00 | 1.00 - 1.05 | | **Silicon (Si)** | 0.10 - 0.40 | 0.10 - 0.40 | 0.10 - 0.40 | | **Manganese (Mn)** | 0.20 - 0.40 | 1.00 - 1.20 | 0.40 - 0.60 | | **Chromium (Cr)** | 11.0 - 12.0 | 0.40 - 0.60 | 4.80 - 5.50 | | **Molybdenum (Mo)** | 0.70 - 0.90 | - | 0.90 - 1.10 | | **Vanadium (V)** | 0.90 - 1.10 | 0.10 - 0.30 | 0.15 - 0.35 | | **Tungsten (W)** | - | 0.40 - 0.60 | - | ## **Physical & Mechanical Properties (Heat-Treated State)** Properties are highly dependent on the specific grade and final heat treatment. Below are typical achievable values for the most common conditions. * **Hardness (Hardened & Tempered):** * **TENASTEEL® A8 (D2):** 58 - 62 HRC (Typical: 60-61 HRC) * **TENASTEEL® O2 (O1):** 58 - 62 HRC (Typical: 59-61 HRC) * **TENASTEEL® A2 (A2):** 57 - 61 HRC (Typical: 58-60 HRC) * **Compressive Strength:** Extremely high, typically > 2500 MPa for grades at 60 HRC. * **Flexural Strength:** Varies by grade; cleaner ESR versions exhibit higher values. * **Impact Toughness:** Generally in the range of 10 - 30 J (Charpy). A2 and O2 typically offer better toughness than D2 at equivalent hardness. * **Dimensional Change during Hardening:** Very low for air-hardening grades (A2, A8/D2). Oil-hardening grade (O2) is designed for minimal distortion. * **Service Temperature:** Recommended for continuous service up to **200 - 250°C**. Above this, hot work tool steels are preferred. ## **Typical Applications** TENASTEEL® grades are used across industries for critical tooling components: * **Blanking, Piercing, and Trimming Dies:** For sheet metal, especially high-strength steels and abrasive materials. * **Cold Forming Tools:** For extrusion, heading, bending, and coining. * **Precision Gauges and Measuring Tools:** Requiring dimensional stability and wear resistance. * **Rolls and Slitters:** For metal strip processing. * **Plastic Injection Molds:** For abrasive or corrosive plastics (filled materials, PVC) and mold inserts requiring high polish (ESR versions). * **Knives and Cutting Blades:** For industrial cutting applications. ## **Processing Guidelines** * **Machining:** Perform all roughing and finishing in the **soft-annealed condition** (~200 HB). Use positive rake tools and adequate cooling. * **Heat Treatment:** Requires precise control. * **Preheating:** Essential to minimize thermal shock (e.g., 650°C, then 850°C). * **Austenitizing:** Temperature is grade-specific (e.g., 1020-1050°C for D2, 780-820°C for O1). * **Quenching:** Air for A2/D2; Oil for O1. * **Tempering:** Double or triple tempering immediately after quenching is mandatory to achieve final hardness, transform retained austenite, and develop optimal toughness. Temper above 180°C. * **Grinding:** Use proper, sharp grinding wheels with light passes and ample coolant to avoid grinding burns and cracks. ESR steels generally exhibit better grindability. * **Surface Treatments:** Excellent substrates for PVD/CVD coatings, nitriding, and other surface enhancements to further boost performance. ## **Summary** **Industeel TENASTEEL®** is the benchmark for high-performance cold work tooling. By leveraging advanced steelmaking technologies, it delivers unparalleled microstructural homogeneity and consistency. This translates directly into tools that offer maximum wear life, reliable fracture resistance, and superior surface finish potential. Whether for high-volume blanking dies, precision forming tools, or demanding plastic molds, TENASTEEL® provides the metallurgical excellence required for the most challenging applications. -:- For detailed product information, please contact sales. -: Industeel TENASTEEL® Cold Work Tool Steel Specification Dimensions Size： Diameter 20-1000 mm Length <5245 mm Size:We can customized as required Standard： Per your request or drawing We can customized as required Properties（Theoretical） Chemical Composition -:- For detailed product information, please contact sales. -: Industeel TENASTEEL® Cold Work Tool Steel Properties -:- For detailed product information, please contact sales. -:
