Latrobe HS-29XL™ ASTM M2-HC High Speed Steel Product Information -:- For detailed product information, please contact sales. -: ### **Product Datasheet: Latrobe HS-29XL™ ASTM M2-HC High-Speed Steel (HSS)** **1. Product Overview** Latrobe HS-29XL™ is a premium, cobalt-enhanced high-speed steel (HSS) grade supplied to the ASTM A600 M2 High Carbon (HC) specification. This grade represents an advanced evolution of the standard M2 chemistry, engineered to deliver superior performance in demanding machining and cutting applications. The "XL" designation signifies its exceptional balance of wear resistance, red hardness (hot hardness), and toughness, making it a top-tier choice for high-productivity tooling. **2. Key Features & Benefits** * **Enhanced Hot Hardness:** The optimized cobalt addition significantly improves the steel's ability to retain hardness and cutting edge integrity at elevated temperatures generated during high-speed machining. * **Superior Wear Resistance:** A high vanadium content promotes the formation of hard, wear-resistant carbides, extending tool life in abrasive materials. * **Excellent Toughness:** A carefully controlled manufacturing process and heat treatment response provide greater toughness than many alternative high-cobalt grades, reducing the risk of chipping and fracture. * **Consistent Performance:** Manufactured under strict quality controls, HS-29XL™ ensures predictable and reliable performance in critical applications. **3. Standard Chemical Composition (Weight %)** HS-29XL™ conforms to and exceeds the requirements for ASTM A600 M2 High Carbon. The typical analysis is: | Element | Content (%) | Element | Content (%) | | :--- | :--- | :--- | :--- | | **Carbon (C)** | 0.90 - 1.00 | **Tungsten (W)** | 5.50 - 6.75 | | **Chromium (Cr)** | 3.75 - 4.50 | **Vanadium (V)** | 2.25 - 2.75 | | **Molybdenum (Mo)**| 4.50 - 5.50 | **Cobalt (Co)** | 7.00 - 9.00 | | **Manganese (Mn)** | 0.15 - 0.40 | **Sulfur (S)** | ≤ 0.03 | | **Silicon (Si)** | 0.20 - 0.45 | **Phosphorus (P)** | ≤ 0.03 | *(Note: The "High Carbon" variant provides increased carbon for better carbide volume and wear resistance compared to standard M2.)* **4. Typical Physical & Mechanical Properties** * **Density:** 8.16 g/cm³ (0.295 lb/in³) * **Thermal Conductivity:** Low, characteristic of high-alloy HSS. * **Coefficient of Thermal Expansion:** Approximately 11.5 x 10⁻⁶ /K (20-400°C) * **Hardness (Annealed):** Maximum 255 HB * **Hardness (Hardened & Tempered):** **66 - 68 HRC** (Achievable with proper heat treatment. Specific hardness depends on application requirements and heat treat parameters). **5. Primary Applications** HS-29XL™ is specifically designed for high-performance metal cutting tools and wear parts, including: * **Cutting Tools:** High-speed drills, taps, end mills, reamers, and broaches for machining hard or abrasive materials (e.g., alloy steels, stainless steels, high-temperature alloys). * **Forming Tools:** Precision punches, dies, and form tools requiring exceptional wear resistance. * **Woodworking Tools:** Industrial knives and cutter heads for processing composite and abrasive wood materials. * **Critical Wear Components:** Parts subject to severe wear in high-stress or elevated-temperature environments. **6. Relevant International Standards** Latrobe HS-29XL™ is produced to meet or exceed the following international standards: * **ASTM A600-92 (Reapproved):** Standard Specification for High-Speed Steel (M2 High Carbon). * **UNS:** T11342 * **Equivalent Designations:** * **AISI:** M2 High Carbon / M2 HC * **DIN:** 1.3348 (with Co) * **ISO:** HS6-5-3-8 (HS Co) * **JIS:** SKH55 (Similar Co-enhanced grade) **7. Availability & Supply** Available as centerless ground rounds, precision ground flats, forgings, and hot-rolled bars. Specific sizes and conditions (annealed, pre-hardened) should be confirmed with Latrobe Specialty Metals or an authorized distributor. **8. Disclaimer** The information provided is typical and for reference purposes. Actual properties can vary based on processing, heat treatment, and section size. For critical applications, consultation with Latrobe's technical service team and conducting application-specific testing is strongly recommended. --- **LATROBE SPECIALTY METALS** *Performance Alloys for Demanding Applications* -:- For detailed product information, please contact sales. -: Latrobe HS-29XL™ ASTM M2-HC High Speed Steel Specification Dimensions Size： Diameter 20-1000 mm Length <5332 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. -: Latrobe HS-29XL™ ASTM M2-HC High Speed Steel Properties -:- For detailed product information, please contact sales. -:
