Latrobe Crusader™ ASTM M3-2 High Speed Steel Product Information -:- For detailed product information, please contact sales. -: ### **Product Datasheet: Latrobe Crusader™ ASTM M3-2 High-Speed Steel (HSS)** **1. Product Overview** Latrobe Crusader™ is a premium, high-vanadium, high-carbon molybdenum-based high-speed steel conforming to the ASTM A600 M3 Class 2 specification. It is engineered as a superior alternative to standard M2 and M35 grades, offering an outstanding balance of **exceptional abrasion resistance** and **good toughness**. The "Crusader" name signifies its capability to handle the most demanding, abrasive machining applications where tool life is limited by wear rather than shock. **2. Key Features & Benefits** * **Superior Abrasion/Wear Resistance:** Contains a significantly higher vanadium content (approximately 3%) compared to M2, resulting in a greater volume of extremely hard vanadium carbides. This makes it ideal for machining abrasive materials. * **Excellent Hot Hardness:** Maintains cutting edge strength and hardness at the high temperatures generated during machining. * **Optimized Balance:** The M3-2 chemistry provides better toughness than the higher-carbon M3 Class 1, offering a more practical balance for a wider range of severe-duty applications. * **Consistent Quality:** Produced with Latrobe's rigorous melt and processing controls to ensure uniformity and predictable performance in heat treatment and application. **3. Standard Chemical Composition (Weight %)** Crusader™ is manufactured to the precise requirements of ASTM A600 M3 Class 2. The typical analysis is: | Element | Content (%) | Element | Content (%) | | :--- | :--- | :--- | :--- | | **Carbon (C)** | 1.15 - 1.25 | **Tungsten (W)** | 5.00 - 6.75 | | **Chromium (Cr)** | 3.75 - 4.50 | **Vanadium (V)** | 2.75 - 3.25 | | **Molybdenum (Mo)**| 4.75 - 6.50 | **Cobalt (Co)** | - | | **Manganese (Mn)** | 0.15 - 0.40 | **Sulfur (S)** | ≤ 0.03 | | **Silicon (Si)** | 0.20 - 0.45 | **Phosphorus (P)** | ≤ 0.03 | *(Note: The key distinction of M3-2 vs. M2 is the higher Carbon and Vanadium for wear resistance, and it contains no added Cobalt, distinguishing it from M36 or other cobalt-bearing grades.)* **4. Typical Physical & Mechanical Properties** * **Density:** ~8.16 g/cm³ (0.295 lb/in³) * **Thermal Conductivity:** Low, characteristic of complex high-alloy HSS. * **Coefficient of Thermal Expansion:** ~11.5 x 10⁻⁶ /K (20-400°C) * **Hardness (Annealed):** Maximum 255 HB * **Hardness (Hardened & Tempered):** **65 - 67 HRC** (Achievable with proper heat treatment. Typically run at the higher end of this range to maximize wear resistance). **5. Primary Applications** Crusader™ (M3-2) is specifically selected for applications where severe abrasive wear is the primary failure mode: * **Cutting Tools:** Form tools, gear hobs, broaches, milling cutters, and high-performance taps/drills for machining **abrasive materials** such as: * High-silicon aluminum alloys * Heat-treated alloy steels * Stainless steels * Composite materials * Plastics with abrasive fillers (e.g., fiberglass) * **Wear Parts:** Punches, dies, and forming tools subject to constant friction and wear. * **Industrial Knives:** Blades for cutting abrasive non-metallic materials like rubber, paper, and certain composites. **6. Relevant International Standards** Latrobe Crusader™ is produced to meet or exceed the following international standards: * **ASTM A600-92 (Reapproved):** Standard Specification for High-Speed Steel (M3 Class 2). * **UNS:** T11343 * **Equivalent Designations:** * **AISI:** M3 Class 2 * **DIN:** 1.3344 * **ISO:** HS6-5-3 * **JIS:** SKH53 **7. Comparison & Selection Guidance** * **vs. M2:** Crusader™ (M3-2) offers significantly better wear resistance but may have slightly lower toughness. Choose M3-2 for abrasive conditions. * **vs. M3 Class 1:** M3-2 has slightly lower carbon, providing better toughness while retaining excellent wear resistance, making it a more versatile choice. * **vs. Cobalt Grades (M35, M42):** Crusader™ lacks cobalt, so it has lower hot hardness but better toughness and is more cost-effective for applications not requiring extreme red hardness. **8.
