Latrobe LSS™ PGK Knife and Die Steel Product Information -:- For detailed product information, please contact sales. -: # **Latrobe LSS™ PGK Knife and Die Steel** ## **Product Overview** Latrobe LSS™ PGK is a proprietary, high-carbon, medium-alloy **air-hardening tool steel** specifically engineered for exceptional performance in cutting, shearing, and forming applications where superior **wear resistance, edge retention, and resistance to chipping** are critical. Developed as a premium-grade alternative to standard industrial knife steels, PGK provides enhanced reliability and extended service life in demanding continuous or high-volume production environments, effectively balancing the need for sharpness durability with toughness to resist failure. ## **Key Features & Benefits** * **Superior Edge Retention & Wear Resistance:** Optimized carbide content and distribution provide excellent resistance to abrasive wear, maintaining a sharp cutting edge longer than conventional knife steels under continuous operation. * **High Resistance to Chipping & Rolling:** Enhanced toughness and fine-grained microstructure offer improved resistance to edge chipping, micro-fracturing, and plastic deformation (edge rolling) under impact or heavy loads. * **Excellent Dimensional Stability:** As an air-hardening steel, it undergoes minimal distortion during heat treatment, ensuring straightness and dimensional accuracy in long blades and precision dies, reducing the need for corrective straightening. * **Good Toughness-to-Hardness Balance:** Engineered to achieve higher hardness levels (for wear resistance) while maintaining sufficient toughness to withstand the mechanical stresses inherent in shearing and cutting operations. * **Consistent & Predictable Performance:** Controlled manufacturing ensures uniform microstructure and properties, providing reliable performance batch after batch. ## **International Standard & Designations** * **Manufacturer's Proprietary Grade:** **Latrobe LSS™ PGK** * This is a proprietary steel chemistry not defined by standard AISI/ASTM nomenclature. The "PGK" designation signifies its application focus on **P**remium **G**rade **K**nife/Die steel. * **Functional Classification:** Premium wear-resistant, air-hardening steel for cutting and forming tools. * **Common Performance Equivalents (Functional):** * Occupies a performance tier above standard industrial grades like 01 or D2 for knife applications. * Comparable in purpose to other proprietary knife/die steels from major producers, such as Crucible's **CPM 3V** (though chemistry differs) or specialized high-wear, high-toughness formulations. ## **Chemical Composition (%, typical - Proprietary)** The composition is designed for a high volume of fine, hard carbides within a tough matrix. | Carbon (C) | Chromium (Cr) | Molybdenum (Mo) | Vanadium (V) | Silicon (Si) | Manganese (Mn) | Other (Proprietary) | Iron (Fe) | | :--- | :--- | :--- | :--- | :--- | :--- | :--- | :--- | | 0.70 - 0.85 | 4.00 - 5.50 | 1.50 - 2.50 | 0.80 - 1.40 | 0.20 - 0.60 | 0.20 - 0.60 | Balance* | Balance | **\*Note:** The exact proprietary balance may include micro-alloying elements to refine grain size or enhance specific properties. Values shown represent the characteristic alloy direction. ## **Physical & Mechanical Properties (Typical)** | Property | Value / Description | | :--- | :--- | | **Density** | ~7.8 g/cm³ (0.282 lb/in³) | | **Hardness (Annealed)** | 210-240 HB (Brinell) | | **Hardness (Heat Treated)** | **58 - 62 HRC** (Standard optimal range for knife and die applications)
Can be tailored from 56 HRC (for maximum toughness) to 63-64 HRC (for extreme wear resistance). | | **Austenitizing Temperature** | 1010 - 1040°C (1850 - 1905°F) – Manufacturer-specific. | | **Quenching Medium** | Air (Still or Forced) | | **Tempering Temperature** | **200 - 540°C (390 - 1000°F).** Commonly tempered in the 425-500°C (800-930°F) range to achieve an optimal combination of hardness, toughness, and dimensional stability. **Double tempering is strongly recommended.** | | **Toughness (Impact Resistance)** | **Good to Very Good.** Significantly higher than D2 at equivalent hardness, providing superior resistance to chipping. | | **Wear Resistance** | **Very Good.** Superior to A2 and comparable to premium-grade D2. | ## **Product Applications** Latrobe LSS™ PGK is the material of choice for high-performance industrial cutting and forming tools. * **Industrial Knives & Blades:** * Slitter knives for metal, plastic, paper, and composite materials. * Shear blades for bar, rod, and plate cutting. * * Guillotine blades, trimmer blades, and scrap choppers. * **Punches and Dies:** * Blanking and piercing dies for abrasive sheet materials. * Fine-blanking dies requiring sharp, durable edges. * **Cutting & Forming Tools:** * Cold saw blades and circular cutters. * Forming rolls and mandrels subject to wear. * **Wear Parts:** * Wear plates, liners, and guides in high-abrasion conveying or processing systems. ## **Processing & Heat Treatment Notes** * **Machining:** Good machinability in the annealed condition. Use sharp tools with positive rake angles. * **Heat Treatment:** Follows standard air-hardening practices. **Essential preheating** (e.g., 650°C/1200°F) is required before austenitizing in a controlled atmosphere furnace. Air quench to below 65°C (150°F). **Temper immediately.** Double tempering at the recommended temperature is crucial for stress relief, toughness development, and stability. * **Grinding & Sharpening:** Exhibits good grindability. For sharpening, use sharp, fine-grit abrasives (AlOx or CBN) with adequate cooling to preserve the metallurgical integrity of the fine edge. * **Surface Treatments:** An excellent candidate for nitriding (gas or plasma) to further enhance surface hardness and anti-galling properties for specific cutting applications. --- **Disclaimer** *Latrobe LSS™ PGK is a proprietary tool steel.
