Latrobe TNW™ ASTM M10 High Speed Steel Product Information -:- For detailed product information, please contact sales. -: ### **Product Datasheet: Latrobe TNW™ ASTM M10 High-Speed Steel (HSS)** --- #### **1. Product Overview** **Latrobe TNW™** is a premium molybdenum-based high-speed steel conforming to **ASTM A600 M10 specifications**. Engineered as a cost-effective yet high-performance alternative to tungsten-dominated grades, TNW™ delivers an exceptional balance of **wear resistance, toughness, and grindability**. Its optimized chemistry—characterized by high molybdenum and controlled tungsten content—makes it particularly suitable for applications requiring durability in general-purpose and moderately demanding machining operations where both performance and tool manufacturing efficiency are critical. --- #### **2. Key Features & Benefits** - **Superior Cost-Performance Ratio:** Provides M2-level performance at a more economical price point due to its molybdenum-rich, low-tungsten formulation - **Excellent Grindability:** Superior to higher-vanadium grades (M3/M4), reducing tool manufacturing time and wheel consumption - **Balanced Wear Resistance & Toughness:** Vanadium content optimized for enhanced wear resistance without compromising shock resistance - **Consistent Heat Treatment Response:** Uniform hardening characteristics ensure predictable performance in production environments - **Versatile Machinability:** Performs well across a broad range of ferrous and non-ferrous materials --- #### **3. Chemical Composition (Weight %)** TNW™ meets ASTM A600 M10 requirements with the following composition: | Element | Specification Range | Typical Analysis | |----------------|---------------------|------------------| | **Carbon (C)** | 0.84–0.94 | 0.88 | | **Molybdenum (Mo)**| 7.75–8.50 | 8.15 | | **Tungsten (W)** | 0.50–1.25 | 0.90 | | **Vanadium (V)** | 1.80–2.20 | 2.00 | | **Chromium (Cr)** | 3.75–4.50 | 4.10 | | **Silicon (Si)** | 0.20–0.45 | 0.30 | | **Manganese (Mn)** | 0.15–0.40 | 0.25 | | **Sulfur (S)** | ≤ 0.03 | 0.015 | | **Phosphorus (P)** | ≤ 0.03 | 0.020 | --- #### **4.
