Assab Steels ASSAB XW-5 Cold Work Steel Product Information -:- For detailed product information, please contact sales. -: # Product Datasheet: Assab Steels ASSAB XW-5 High-Carbon High-Chromium Cold Work Tool Steel ## Product Overview **Assab Steels ASSAB XW-5** is a high-carbon, high-chromium ledeburitic cold work tool steel characterized by exceptionally high wear resistance and good compressive strength. As part of the conventional high-chromium tool steel family, it offers reliable performance for applications requiring maximum abrasion resistance with moderate toughness requirements. ## Key Characteristics & Advantages - **Exceptional Wear Resistance:** High carbide content (primarily chromium carbides) provides outstanding resistance to abrasive wear - **Good Compressive Strength:** Capable of withstanding high loading pressures without deformation - **Fair Dimensional Stability:** Exhibits predictable and manageable dimensional changes during heat treatment - **Good Through-Hardenability:** Can be air hardened in substantial sections with uniform properties - **Economic Alternative:** Provides a cost-effective solution compared to more highly alloyed powder metallurgy steels for many applications ## Standard Specifications & International Designations | **Standard** | **Designation** | |--------------|-----------------| | **Assab/Uddeholm** | XW-5 | | **AISI/ASTM** | D3 | | **DIN/EN** | 1.2080 (X210Cr12) | | **JIS** | SKD1 | | **ISO** | 160CrMoV12 | | **UNS** | T30403 | | **GB** | Cr12 | ## Chemical Composition (Typical, Weight %) | Element | Content (%) | Element | Content (%) | |---------|-------------|---------|-------------| | **Carbon (C)** | 2.00-2.10 | **Chromium (Cr)** | 11.0-12.0 | | **Molybdenum (Mo)** | 0.60-0.80 | **Vanadium (V)** | 0.20-0.30 | | **Manganese (Mn)** | 0.40-0.60 | **Silicon (Si)** | 0.20-0.40 | | **Sulfur (S)** | ≤0.020 | **Phosphorus (P)** | ≤0.025 | | **Iron (Fe)** | Balance | ## Typical Heat Treatment ### Annealing - **Process:** Heat to 850-870°C (1560-1600°F), slow cool at 10-20°C/hour to 600°C, then air cool - **Resulting Hardness:** 200-230 HB ### Stress Relieving - **Temperature:** 600-650°C (1110-1200°F) after rough machining ### Hardening 1. **Preheating:** 650°C (1200°F) and 800°C (1470°F) - two-stage recommended 2. **Austenitizing:** **950-980°C (1740-1800°F)** - soak thoroughly (30-45 minutes depending on section size) 3. **Quenching:** Cool in still **air** or forced air (for simpler shapes) or in **oil** (for complex shapes to minimize cracking risk) ### Tempering - **Immediate tempering** after quenching is critical - **Double tempering** recommended: 180-250°C (355-480°F) for cold work applications - **Alternative tempering:** 400-550°C (750-1020°F) for applications requiring higher toughness (with corresponding hardness reduction) - **Typical Hardness Range:** 58-62 HRC (when tempered at 200°C) ## Typical Physical & Mechanical Properties (Hardened & Tempered) | Property | Value | Unit | |----------|-------|------| | **Density** | 7.70 | g/cm³ | | **Modulus of Elasticity** | 210 | GPa | | **Thermal Expansion Coefficient (20-100°C)** | 10.4 | ×10⁻⁶/K | | **Thermal Conductivity (20°C)** | 20.0 | W/(m·K) | | **Specific Heat Capacity (20°C)** | 460 | J/(kg·K) | | **Hardness (Tempered at 200°C)** | 60-62 | HRC | | **Compressive Strength (60 HRC)** | ~2,500 | MPa | | **Toughness** | Moderate | - | ## Primary Applications ASSAB XW-5 is suitable for applications where wear resistance is the primary concern: ### Cutting and Shearing Applications - **Blanking and Piercing Dies** for medium to long production runs - **Shear Blades and Slitter Knives** for metal and non-metallic materials - **Cut-off Tools and Inserts** ### Forming Applications - **Cold Forming Rolls** and **Thread Rolling Dies** - **Drawing Dies** for wires and bars (particularly for abrasive materials) - **Bending and Forming Tools** ### Other Specialized Applications - **Brick and Tile Molds** for abrasive ceramic materials - **Plastic Molds** for processing filled/reinforced plastics - **Wear Plates and Guides** in machinery - **Gauges and Measuring Tools** requiring extreme wear resistance - **Woodworking Tools** for processed wood products ## Processing Guidelines ### Machining - **Recommended Condition:** Soft-annealed state (~220 HB) - **Tool Requirements:** Use sharp tools with positive rakes - **Machinability Rating:** Fair (40-50% compared to 1% C-steel) ### Electrical Discharge Machining (EDM) - Suitable for EDM processing - **Post-EDM Recommendation:** Stress relief at 150-200°C after roughing operations - **Surface Condition:** White layer formation may require removal by polishing or additional tempering ### Grinding - Use proper grinding techniques to avoid thermal cracking - Employ adequate coolant flow - Consider multi-pass grinding with light cuts ### Welding - **Not generally recommended** for tool repair due to high cracking susceptibility - **If necessary:** Preheating to 300-400°C required - Use matching electrodes and follow with full re-hardening cycle - Consider alternative repair methods (inserts, mechanical fastening) ### Surface Treatment - Excellent candidate for **nitriding** (gas, plasma, or salt bath) - Suitable for **PVD coatings** (TiN, TiCN, CrN) after proper surface preparation - **Polishing:** Can achieve good surface finish with proper techniques ## Comparative Performance Notes - **Wear Resistance:** Superior to A2, O1, and S7 grades - **Toughness:** Lower than A2 and S7 but comparable to other high-chromium grades - **Dimensional Stability:** Good, but requires careful heat treatment control - **Deep-Hardening:** Excellent, with minimal size change in air hardening ## Available Forms & Sizes - **Precision Ground Flat Stock:** Various thicknesses and widths - **Forged Blocks:** Custom dimensions available - **Bars:** Round, square, and hexagonal sections - **Pre-finished Modules:** For mold and die applications ## Special Considerations 1. **Decarburization Sensitivity:** Requires adequate stock allowance for machining after heat treatment 2. **Carbide Segregation:** Larger sections may exhibit some carbide banding 3. **Cracking Tendency:** Higher risk during heat treatment compared to lower alloy steels - requires careful process control 4. **Annealing Criticality:** Proper annealing is essential for subsequent machining and heat treatment success --- **Disclaimer:** The information provided herein is for reference purposes only. ASSAB XW-5 performance is highly dependent on proper heat treatment and processing.
