Common sizes for metric carbon steel angle stock typically include a range of leg lengths and thicknesses. The leg lengths can vary from small to large, often starting at around 20 mm and going up to 200 mm or more. Thicknesses can range from about 3 mm to 20 mm or more, depending on the specific requirements and applications. For example, some standard sizes might include: - 20 mm x 20 mm x 3 mm - 30 mm x 30 mm x 3 mm - 50 mm x 50 mm x 5 mm - 75 mm x 75 mm x 6 mm - 100 mm x 100 mm x 10 mm - 150 mm x 150 mm x 12 mm - 200 mm x 200 mm x 20 mm These sizes are typically available in lengths of 6 meters or 12 meters, but custom lengths can often be ordered. The specific sizes available can vary by manufacturer and supplier, and custom sizes can often be produced to meet specific project requirements.

Metric carbon steel angle stock is a versatile construction material used for its strength, durability, and ease of fabrication. It is commonly employed in structural applications due to its L-shaped cross-section, which provides excellent load-bearing capacity and resistance to bending. This makes it ideal for reinforcing structures, creating frames, and supporting beams. In construction, carbon steel angle stock is often used to form the skeleton of buildings, bridges, and towers. It serves as a critical component in frameworks, providing stability and support for walls, floors, and roofs. The angles can be bolted, welded, or riveted together, allowing for flexible design and assembly. Additionally, carbon steel angle stock is used in the construction of shelving, racks, and other storage solutions due to its ability to support heavy loads. It is also employed in the fabrication of brackets, reinforcements, and braces, which are essential for maintaining the integrity of various structures. The material's resistance to corrosion and wear makes it suitable for outdoor and industrial applications, where it can withstand harsh environmental conditions. Its availability in various sizes and thicknesses allows for customization to meet specific project requirements. Overall, metric carbon steel angle stock is a fundamental material in construction, valued for its strength, versatility, and adaptability in a wide range of structural and architectural applications.

Metric carbon steel angle stock is available in several material grades, each with distinct properties and applications. The most common grades include: 1. **S235JR (1.0038):** This is a non-alloy structural steel grade with good weldability and machinability. It is often used in construction and engineering applications. 2. **S275JR (1.0044):** Slightly stronger than S235JR, this grade is also used in structural applications. It offers good weldability and is suitable for general engineering purposes. 3. **S355JR (1.0045):** Known for its higher strength compared to S235JR and S275JR, S355JR is used in more demanding structural applications. It provides good weldability and impact resistance. 4. **S355J2 (1.0577):** This grade is similar to S355JR but with improved impact resistance at lower temperatures. It is often used in cold environments. 5. **S355K2 (1.0596):** Offers even better impact resistance at low temperatures than S355J2, making it suitable for very cold climates. 6. **C45 (1.0503):** A medium carbon steel grade, C45 is used when higher strength and hardness are required. It is often used in manufacturing machinery parts. 7. **C60 (1.0601):** A high carbon steel grade, C60 is used for applications requiring high strength and wear resistance, such as in the production of springs and high-strength components. 8. **EN8 (080M40):** A medium carbon steel with good tensile strength, often used for shafts, stressed pins, studs, keys, etc. These grades are selected based on the required mechanical properties, such as tensile strength, yield strength, and impact resistance, as well as the specific application and environmental conditions.

1. **Identify Material Properties**: Obtain the yield strength and tensile strength of the carbon steel from material standards or supplier data. 2. **Determine Cross-Sectional Properties**: Calculate the moment of inertia (I) and section modulus (S) for the angle section. Use standard formulas for L-shaped sections or refer to engineering handbooks. 3. **Identify Loading Conditions**: Determine the type of load (axial, bending, torsional) and the loading configuration (point load, distributed load). 4. **Calculate Axial Load Capacity**: Use the formula \( P = A \times \sigma_y \), where \( P \) is the axial load capacity, \( A \) is the cross-sectional area, and \( \sigma_y \) is the yield strength. 5. **Calculate Bending Load Capacity**: Use the formula \( M = S \times \sigma_y \), where \( M \) is the bending moment capacity and \( S \) is the section modulus. 6. **Check for Buckling**: For long slender angles, calculate the critical buckling load using Euler's formula \( P_{cr} = \frac{\pi^2 \times E \times I}{(K \times L)^2} \), where \( E \) is the modulus of elasticity, \( K \) is the effective length factor, and \( L \) is the unsupported length. 7. **Consider Combined Loading**: If the angle is subject to combined axial and bending loads, use interaction formulas to ensure combined stresses do not exceed allowable limits. 8. **Apply Safety Factors**: Incorporate safety factors as per design codes to ensure the calculated load capacity is within safe limits. 9. **Verify with Design Codes**: Cross-check calculations with relevant design standards (e.g., Eurocode, AISC) for compliance. 10. **Consult Engineering Software**: For complex loading or geometry, use structural analysis software for precise calculations.
