Latrobe DuraTech™ 30 Powder Metal High Speed Steel (ASTM M3-2) Product Information -:- For detailed product information, please contact sales. -: # **Latrobe DuraTech™ 30 Powder Metal High Speed Steel (ASTM M3-2)** ## **Product Overview** Latrobe DuraTech™ 30 is a premium-grade powder metallurgy (PM) high-speed steel engineered to exceed the requirements of ASTM M3 Class 2. Utilizing advanced gas atomization and hot isostatic pressing (HIP) technology, this material achieves an exceptionally uniform microstructure characterized by fine, evenly distributed carbides. This advanced manufacturing process eliminates the carbide segregation inherent in conventional ingot metallurgy, resulting in a superior balance of **extreme wear resistance**, **high toughness**, and **excellent grindability**. DuraTech™ 30 is specifically designed for the most demanding cutting and forming applications where maximum tool life and reliability under severe abrasive conditions are critical. ## **Key Features & Benefits** * **Unparalleled Microstructural Homogeneity:** The PM process ensures a consistent, isotropic structure free from large, brittle carbide networks, providing uniform performance in all directions. * **Exceptional Abrasive Wear Resistance:** A very high vanadium content (approx. 3%) combined with a fine dispersion of hard, primary MC-type carbides delivers outstanding resistance to wear, significantly extending tool life in abrasive machining operations. * **Superior Toughness & Impact Resistance:** The fine, homogeneous carbide structure provides enhanced toughness compared to conventional M3-2, reducing susceptibility to chipping and micro-fracturing in interrupted cuts and demanding tool geometries. * **Enhanced Grindability & Machinability:** Despite its high alloy content, the rounded carbide morphology of the PM material allows for easier grinding, facilitating the production of sharper, more complex cutting edges with reduced risk of grinding burns. * **Consistent Performance:** Guarantees predictable and repeatable performance across all cross-sections, essential for precision tool manufacturing and high-volume production. ## **International Standard & Designations** * **Primary Standard:** **ASTM A600-92a (R2023):** Standard Specification for Tool Steel High Speed. * **Grade:** **M3 Class 2** (PM / Particle Metallurgy variant) * **Manufacturing Process:** **Powder Metallurgy, Hot Isostatically Pressed (PM-HIP)** * **Unified Numbering System (UNS):** **T11323** * **Common International Equivalents (PM-based, for reference):** * **Sweden (SS):** **ASP® 2030** (Höganäs equivalent) * **ISO PM Designation:** Often aligned with **HS 6-5-3-8** performance category. * **Conventional Ingot Equivalent:** **ASTM M3-2** (AISI M3-2) ## **Chemical Composition (%, typical)** The composition is optimized for a high volume of hard, wear-resistant vanadium carbides within a tough matrix. | Carbon (C) | Tungsten (W) | Molybdenum (Mo) | Vanadium (V) | Chromium (Cr) | Cobalt (Co) | Iron (Fe) | | :--- | :--- | :--- | :--- | :--- | :--- | :--- | | 1.15 - 1.30 | 5.75 - 6.75 | 4.75 - 6.00 | 2.75 - 3.25 | 3.75 - 4.75 | 7.75 - 8.75 | Balance | *Note:* The significant cobalt content (approx. 8%) enhances red-hardness (hot hardness), allowing the tool to maintain its cutting edge at very high temperatures generated during high-speed machining. ## **Physical & Mechanical Properties (Typical)** | Property | Value / Description | | :--- | :--- | | **Density** | ~8.1 g/cm³ (0.293 lb/in³) | | **Hardness (Annealed)** | ≤ 285 HB (Brinell) | | **Hardness (Heat Treated)** | **66 - 68 HRC** (Typical optimal working range) | | **Austenitizing Temperature** | 1190 - 1220°C (2175 - 2230°F) | | **Tempering Temperature** | 540 - 580°C (1000 - 1075°F) (Minimum of two, typically three tempers required) | | **Transverse Rupture Strength** | Very high for its hardness class, a direct benefit of the uniform PM microstructure. | | **Red Hardness** | Excellent, capable of maintaining high hardness at temperatures exceeding 600°C (1110°F) due to cobalt addition. | ## **Product Applications** Latrobe DuraTech™ 30 is the ultimate choice for high-performance tools that must withstand extreme abrasive wear and high thermal loads. * **High-Performance Cutting Tools:** * Premium end mills for machining hardened steels (>50 HRC), superalloys (Inconel, Waspaloy), and abrasive composites. * Gear hobs and skiving tools for high-precision, high-volume gear manufacturing. * Broaches for tough and abrasive materials. * Indexable inserts and form tools for severe-duty turning and milling. * Solid carbide drill alternatives for deep-hole drilling in abrasive materials. * **Cold & Hot Work Tooling:** * High-wear blanking and punching dies for advanced high-strength steels (AHSS) and silicon steels. * Thread rolling and form rolling dies requiring extreme wear life. * Extrusion dies and wear parts for abrasive non-ferrous materials. * **Target Workpiece Materials:** * Hardened tool and die steels (HRc 50-65) * Nickel-based and cobalt-based superalloys * Titanium alloys * Abrasive cast irons (e.g., compacted graphite iron - CGI) * Stainless steels (work-hardening grades like 304, 316) * Heat-resistant alloys (HRAs) ## **Processing Notes** * **Heat Treatment:** Requires precise temperature control. Vacuum or controlled atmosphere furnaces are mandatory to prevent decarburization and oxidation. The fine PM microstructure allows for consistent response to heat treatment with minimal distortion. * **Grinding:** Use sharp, premium CBN or aluminum oxide grinding wheels with appropriate coolants. The superior grindability of the PM structure allows for efficient stock removal even at high hardness levels. * **Availability:** Supplied as fully annealed, spheroidize-annealed bars, billets, or near-net-shape blanks. The PM-HIP process enables large, sound sections impossible with conventional casting. ## **Disclaimer** *This information is for descriptive and informational purposes only.
