Description of 50 Carbon Steel Sheet (0.7 mm Thickness) 50 carbon steel is a medium-carbon steel known for its balanced combination of strength, ductility, and machinability. With a carbon content of approximately 0.50%, this grade offers higher tensile strength and hardness compared to low-carbon steels while retaining sufficient formability for various fabrication processes. The 0.7 mm thickness makes it suitable for applications requiring lightweight yet durable material, such as automotive components, machinery parts, and structural reinforcements. Material Properties - Carbon Content: ~0.50%, providing enhanced hardness and wear resistance. - Tensile Strength: Typically ranges between 620–790 MPa, ensuring structural integrity under stress. - Elongation: Moderate ductility (around 10–15% elongation), allowing for bending and forming without cracking. - Hardness: Approximately 170–210 HB (Brinell hardness), making it resistant to abrasion. - Weldability: Requires preheating and post-weld heat treatment to avoid cracking due to its carbon content. - Machinability: Fairly good but may require cutting tools with proper lubrication to reduce wear. Applications The 0.7 mm thin sheet is ideal for: 1. Automotive Panels: Lightweight body panels, brackets, and reinforcements. 2. Industrial Components: Gears, shafts, and tooling parts requiring wear resistance. 3. Construction: Reinforcements or cladding where moderate strength is needed. 4. Household Goods: Blades, springs, and hardware requiring durability. Fabrication Considerations - Cutting: Laser, plasma, or shear cutting can be used, though edges may require deburring. - Bending: Possible with proper tooling to avoid stress concentrations. - Surface Treatment: Prone to corrosion; coatings (e.g., galvanizing, painting) or regular maintenance are recommended. Advantages - Cost-Effective: More affordable than high-alloy steels while offering superior mechanical properties to low-carbon grades. - Versatility: Adaptable to welding, machining, and forming with proper techniques. Limitations - Corrosion Sensitivity: Requires protective treatments in humid or corrosive environments. - Thermal Sensitivity: Hardening processes must be controlled to prevent brittleness. In summary, 50 carbon steel sheets (0.7 mm) provide an excellent balance of strength and workability for industrial and commercial uses, though proper handling and finishing are essential to maximize performance.
