ASTM A606 HSLA Steel, Cold Rolled Sheet Product Information -:- For detailed product information, please contact sales. -: ### **ASTM A606 HSLA Steel, Cold Rolled Sheet** #### **1. Overview** ASTM A606 is a specification for **high-strength low-alloy (HSLA) steel** supplied as **cold-rolled sheet and strip**, featuring **enhanced atmospheric corrosion resistance**. This weathering steel develops a protective oxide patina when exposed to weather, providing approximately **two times better corrosion resistance** than conventional carbon steel. The cold-rolling process provides superior surface finish, tighter dimensional tolerances, and improved mechanical properties compared to hot-rolled products, making it ideal for applications requiring both aesthetic appeal and structural performance. #### **2. Chemical Composition** The chemical composition is optimized for cold-rolling and corrosion resistance: | Element | Composition (%) | |---------|-----------------| | Carbon (C) | 0.22 max | | Manganese (Mn) | 0.60 - 1.25 | | Phosphorus (P) | 0.04 - 0.12 | | Sulfur (S) | 0.05 max | | Silicon (Si) | 0.25 - 0.75 | | Copper (Cu) | 0.20 - 0.40 | | Chromium (Cr) | 0.30 - 1.25 | | Nickel (Ni) | 0.25 max | **Enhanced Composition Features:** - **Copper-Chromium-Phosphorus System**: Forms dense, adherent protective patina - **Controlled Carbon Content**: Ensures good cold workability - **Phosphorus Enhancement (0.04-0.12%)**: Significantly improves atmospheric corrosion resistance - **Balanced Alloy System**: Optimized for cold-rolling process #### **3. Physical & Mechanical Properties** **Mechanical Properties:** | Property | Requirement | |----------|-------------| | **Tensile Strength** | 70 ksi min (485 MPa min) | | **Yield Strength** | 50 ksi min (345 MPa min) | | **Elongation in 2 inches** | 22% min | | **Rockwell Hardness (HRB)** | 80 max | | **Bend Test** | Bend 180° around diameter equal to thickness | **Enhanced Performance Characteristics:** - **Superior Surface Finish**: Excellent for visible applications - **Enhanced Dimensional Accuracy**: Tight thickness and flatness tolerances - **Improved Strength**: Cold working increases strength properties - **Atmospheric Corrosion Resistance**: 2x better than carbon steel **Physical Properties (Typical):** - **Density**: 0.284 lb/in³ (7,850 kg/m³) - **Modulus of Elasticity**: 29,000 ksi (200 GPa) - **Poisson's Ratio**: 0.29 - **Surface Roughness**: 0.5 - 2.5 μm Ra - **Thermal Conductivity**: 43.0 W/m·K at 212°F (100°C) #### **4. Product Applications** A606 cold-rolled sheet is used in applications requiring superior surface quality: **Architectural Applications:** - Premium architectural wall panels - High-end building facades - Decorative structural elements - Interior design features **Transportation Equipment:** - Truck and trailer exterior panels - Railway car interior and exterior panels - Automotive body components - Recreational vehicle panels **Consumer Products:** - Appliance exterior panels - Furniture components - Electronic enclosures - Display and signage panels **Industrial Equipment:** - Control panel enclosures - Machine covers and guards - Instrument housings - Precision equipment parts #### **5. International Standards & Equivalents** | Region/Country | Standard | Equivalent Grade | Notes | |----------------|----------|------------------|-------| | **International** | **ISO 4952** | E460D | Cold-rolled weathering steel | | **Europe** | **EN 10169** | S350G+Z | Continuously organic coated steel | | **Japan** | **JIS G3141** | SPCC-SD | Cold-rolled carbon steel | | **China** | **GB/T 5213** | SPCC | Cold-rolled carbon steel | **Surface Finish Options:** | Finish Type | Surface Roughness (Ra) | Typical Applications | |-------------|---------------------|---------------------| | **Matte Finish** | 1.0 - 2.5 μm | General forming applications | | **Bright Finish** | 0.5 - 1.2 μm | Visible exterior applications | | **Extra Smooth** | 0.3 - 0.8 μm | Premium architectural uses | #### **6.
