Latrobe CM-52™ ASTM M52 High Speed Steel Product Information -:- For detailed product information, please contact sales. -: **Latrobe CM-52™ ASTM M52 High Speed Steel** **Product Overview** Latrobe CM-52™ is a versatile and high-performance molybdenum-based high-speed steel conforming to the ASTM M52 standard. Designed as a balanced, economical alternative to higher-cobalt grades, CM-52™ offers an excellent combination of **high hot hardness, good wear resistance, and superior toughness**. Its optimized alloy composition provides enhanced performance for a wide range of cutting and forming applications, particularly where resistance to edge chipping and thermal fatigue is critical. This grade is especially valued in scenarios demanding durability under intermittent cutting or impact conditions. **Key Features & Benefits** * **Excellent Toughness:** Provides superior resistance to chipping and breakage compared to many higher-vanadium grades, making it ideal for interrupted cuts and demanding tool geometries. * **High Hot Hardness:** Maintains cutting edge integrity at elevated temperatures, enabling efficient machining at moderate to high speeds. * **Good Wear Resistance:** Balanced carbide composition ensures adequate resistance to abrasive wear for extended tool life. * **Cost-Effective Performance:** Offers a favorable price-to-performance ratio, delivering robust capabilities without the premium cost of high-cobalt or high-tungsten alloys. * **Reliable Grindability:** Exhibits good grinding characteristics, facilitating the manufacture of complex tool shapes and sharp cutting edges. **International Standard & Designations** * **Primary Standard:** **ASTM A600-92a (R2023):** Standard Specification for Tool Steel High Speed. * **Grade:** **M52** * **Unified Numbering System (UNS):** **T11352** * **Common International Equivalents:** * **ISO:** **HS 2-9-2-8** (Closest functional equivalent, though composition differs) * **Germany (DIN/W-Nr.):** **Approx. 1.2601 / S 6-5-3** (Similar performance category) * **Japan (JIS):** **SKH55** **Chemical Composition (%, typical)** The composition of CM-52™ is engineered for a robust balance of properties. | Carbon (C) | Molybdenum (Mo) | Tungsten (W) | Vanadium (V) | Chromium (Cr) | Cobalt (Co) | Iron (Fe) | | :--- | :--- | :--- | :--- | :--- | :--- | :--- | | 0.85 - 0.95 | 4.00 - 4.50 | 0.75 - 1.50 | 1.75 - 2.25 | 3.50 - 4.30 | 0.75 - 1.25 | Balance | *Note: The moderate cobalt content enhances secondary hardening and hot hardness without excessively compromising toughness.* **Physical & Mechanical Properties (Typical)** | Property | Value / Description | | :--- | :--- | | **Density** | 8.0 g/cm³ (0.289 lb/in³) | | **Hardness (Annealed)** | ≤ 255 HB (Brinell) | | **Hardness (Heat Treated)** | **64 - 66 HRC** (Typical achievable working hardness) | | **Austenitizing Temperature** | 1190 - 1220°C (2175 - 2230°F) | | **Tempering Temperature** | 540 - 595°C (1000 - 1105°F) (Double or triple tempering required) | **Product Applications** Latrobe CM-52™ is well-suited for a broad spectrum of cutting and forming tools that require a reliable balance of hardness, toughness, and red-hardness. * **Cutting Tools:** * End mills (especially for milling alloy steels and stainless steels) * Drills, taps, and reamers for demanding materials * Gear hobs and shaper cutters * Broaches for medium-duty applications * Form tools and inserts * **Forming & Wear Parts:** * Cold heading dies and punches * * Thread rolling dies * Slitter knives and shear blades * Wear-resistant guides and components * **Target Workpiece Materials:** * Medium to high-strength alloy steels * Stainless steels (austenitic and martensitic) * Tool steels * Certain high-temperature alloys (at moderate speeds) **Processing Notes** * **Heat Treatment:** Requires careful control during austenitizing to achieve optimal solutioning of carbides. Multiple tempering cycles are essential to achieve maximum secondary hardness and transform retained austenite. Protection against decarburization (via vacuum, atmosphere, or salt bath) is crucial. * **Machinability:** Fair machinability in the annealed condition. Its balanced alloy content provides good response to grinding operations. * **Availability:** Typically supplied as hot-rolled or forged bars, precision ground stock, and billets in the annealed (soft) condition. **Disclaimer** This information is provided for descriptive and informational purposes only.
