Latrobe Dynavan™ ASTM T15 Super High Speed Steel Product Information -:- For detailed product information, please contact sales. -: ### **Latrobe Dynavan™ ASTM T15 Super High Speed Steel (HSS)** **Product Overview** Latrobe Dynavan™ T15 is a premium-grade tungsten-based super high-speed steel manufactured to the exacting ASTM A600 standard. It represents the pinnacle of high-speed steel performance, specifically engineered for the most demanding machining applications. Characterized by an exceptionally high vanadium and tungsten content, Dynavan™ T15 delivers superior **red-hardness** (the ability to retain hardness at elevated temperatures), outstanding **wear resistance**, and excellent **cutting edge retention**. This makes it the material of choice for cutting tools operating under severe conditions where extreme abrasion and heat are primary failure modes. **Key Features & Benefits** * **Unmatched Wear Resistance:** The high vanadium carbide content provides exceptional resistance to abrasive wear, significantly extending tool life. * **Superior Red-Hardness:** Maintains a high degree of hardness at temperatures exceeding 600°C, enabling effective high-speed machining. * **Excellent Edge Strength:** Offers a good balance between toughness and hardness, resisting chipping in demanding cuts. * **Premium Quality & Consistency:** Latrobe's proprietary manufacturing process ensures a homogeneous microstructure, consistent performance, and superior grindability for precise tool fabrication. **International Standard & Designations** * **Primary Standard:** **ASTM A600-92a (R2023):** Standard Specification for Tool Steel High Speed. * **Grade:** **T15** * **Unified Numbering System (UNS):** **T12015** * **Common International Equivalents:** * **ISO:** **HS 12-1-5-5** * **Germany (DIN/W-Nr.):** **1.3202 / S 12-1-4-5** * **Japan (JIS):** **SKH10** **Chemical Composition (%, typical)** The outstanding properties of Dynavan™ T15 are derived from its optimized alloy composition. | Carbon (C) | Tungsten (W) | Vanadium (V) | Cobalt (Co) | Chromium (Cr) | Molybdenum (Mo) | Iron (Fe) | | :--- | :--- | :--- | :--- | :--- | :--- | :--- | | 1.50 - 1.60 | 12.00 - 13.00 | 4.50 - 5.00 | 4.75 - 5.25 | 3.75 - 5.00 | ≤ 1.00 | Balance | *Note: Cobalt enhances red-hardness and hot strength, allowing tools to perform at higher cutting speeds.* **Physical & Mechanical Properties (Typical, Annealed Condition)** | Property | Value / Description | | :--- | :--- | | **Density** | 8.17 g/cm³ (0.295 lb/in³) | | **Hardness (Annealed)** | ≤ 277 HB (Brinell) / ≤ 293 HV (Vickers) | | **Hardness (Heat Treated)** | **66 - 68 HRC** (Typical achievable working hardness after proper heat treatment) | | **Austenitizing Temperature** | 1260 - 1290°C (2300 - 2355°F) | | **Tempering Temperature** | 540 - 595°C (1000 - 1105°F) (Multiple tempers required) | **Product Applications** Latrobe Dynavan™ T15 is specifically designed for single-point and multi-point cutting tools that require maximum wear resistance for machining abrasive and/or hard-to-machine materials. * **Tool Types:** * Broaches (especially for tough alloys) * Gear hobs and shaper cutters * Complex form tools and inserts * High-performance milling cutters * Turning tools for severe duty * Thread rolling and forming dies * **Target Workpiece Materials:** * High-temperature alloys (e.g., Inconel, Waspaloy) * High-strength alloy steels (hardened/tempered) * Abrasive cast irons (e.g., Ni-Hard) * Stainless steels (work-hardening grades) * Titanium alloys * Superalloys **Processing Notes** * **Heat Treatment:** Requires precise and controlled austenitizing and multiple-stage tempering processes to achieve optimal properties. It is sensitive to decarburization and must be treated in a protective atmosphere or vacuum furnace. * **Machinability:** In its annealed state, it has poor machinability compared to lower-alloy steels. Grinding is the primary method for finishing hardened tools. * **Availability:** Typically supplied as precision ground or peeled rounds, squares, flats, and drill rod in the annealed (soft) condition for tool manufacture. **Disclaimer** This information is provided for descriptive purposes only. Properties can vary based on processing, heat treatment, and final product form. Users should conduct their own testing to determine the suitability of Dynavan™ T15 for a specific application.
