Astralloy 8000® Abrasion-Resistant Steel Product Information -:- For detailed product information, please contact sales. -: # Astralloy 8000® Abrasion-Resistant Steel Plate ## Product Overview Astralloy 8000® is an ultra-high hardness, through-hardened abrasion-resistant steel plate engineered for extreme wear applications where maximum resistance to sliding abrasion is required. This premium alloy steel delivers consistent **500 Brinell (HB)** minimum hardness throughout the entire plate thickness, providing superior wear life in highly abrasive environments without the need for additional heat treatment by the end user. ## Key Features & Advantages - **Guaranteed Hardness:** Minimum 500 HB (53 HRC) hardness throughout the entire plate thickness - **Ready-to-Use Condition:** Supplied in the fully hardened and tempered condition, eliminating the need for post-fabrication heat treatment - **Excellent Weldability:** Specifically formulated for improved weldability compared to conventional 500 HB steels - **Good Formability:** Can be cold-formed within recommended radii, facilitating component manufacturing - **Superior Abrasion Resistance:** Outperforms lower hardness AR steels (AR400, AR450) in severe abrasion applications - **Impact Toughness:** Balanced chemistry provides better impact resistance than cast materials of similar hardness ## Chemical Composition (Typical Weight %) Astralloy 8000® features a carefully balanced alloy design optimized for both hardness and toughness: | Element | Composition (%) | Element | Composition (%) | |---------|----------------|---------|----------------| | Carbon (C) | 0.30 - 0.35 | Chromium (Cr) | 0.80 - 1.20 | | Manganese (Mn) | 1.20 - 1.60 | Molybdenum (Mo) | 0.20 - 0.40 | | Silicon (Si) | 0.40 - 0.70 | Boron (B) | 0.001 - 0.005 | | Phosphorus (P) | ≤ 0.020 | Sulfur (S) | ≤ 0.010 | | **Optional Additions:** | Nickel (Ni), Vanadium (V) for enhanced properties | ## Physical & Mechanical Properties ### Mechanical Properties (Typical) - **Hardness:** 500 - 550 HB (53 - 55 HRC) minimum throughout thickness - **Yield Strength:** ≥ 1450 MPa (210 ksi) - **Tensile Strength:** ≥ 1600 MPa (232 ksi) - **Elongation in 2" (50 mm):** 10 - 14% - **Charpy V-Notch Impact (at -20°C/-4°F):** ≥ 20 J (15 ft-lb) ### Physical Properties - **Density:** 7.85 g/cm³ (0.284 lb/in³) - **Modulus of Elasticity:** 200 GPa (29 × 10⁶ psi) - **Thermal Conductivity:** 42 W/m·K at 20°C - **Coefficient of Thermal Expansion:** 11.5 × 10⁻⁶/°C (20-100°C) ## Processing Characteristics ### Machining - Requires carbide-tipped or ceramic cutting tools - Recommended slow speeds with positive rake angles - Adequate cooling/lubrication essential for tool life ### Welding - **Preheat:** 150-200°C (300-400°F) for thicknesses > 12 mm - **Interpass Temperature:** Maintain below 250°C (480°F) - **Recommended Electrodes:** Matching or slightly undermatching strength (500-550 MPa yield) - **Post-Weld Heat Treatment:** Generally not required for most applications ### Forming - Minimum bend radii: 5 × plate thickness (90° bend) - Cold forming possible with proper equipment and techniques ## International Standards & Equivalents Astralloy 8000® meets or exceeds multiple international abrasion-resistant steel specifications: | Standard | Grade | Specification | |----------|-------|---------------| | **ASTM A514/A517** | Grade S | High-yield-strength, quenched & tempered alloy steel | | **EN 10025-6** | S500Q/S500QL | Quenched and tempered fine grain structural steel | | **ISO 4950-3** | Q550QR | High yield strength quenched and tempered plate | | **JIS G3124** | SHY685 | High yield strength steel plates for welded structure | | **AS/NZS 3678** | 500 | High-strength structural steel plate | | **Common Industry Designation:** | AR500 | Abrasion-resistant steel, 500 HB hardness | *Note: While Astralloy 8000® meets these general specifications, it offers proprietary enhancements in consistency, weldability, and through-hardness characteristics.* ## Typical Applications ### Mining & Mineral Processing -
