NM450 bend radius vs a 36 steel plate


    
    Bend radius is an important factor to consider when working with metal plate, as it affects the amount of force needed to form a desired curve. The bend radius is determined by the thickness and hardness of the material and the bending process used. It is important to understand the requirements of the project to determine the correct bend radius for the specific plate.
    
    The bend radius of a 36 steel plate is affected by the type and thickness of the plate. Thicker materials require higher bend radii than thinner plates. The yielding strength of the plate and the method of bending also play a role in determining the bend radius. For example, CNC laser cutting produces more accurate and repeatable results than traditional methods, resulting in smaller bend radii. Heat treating a steel plate reduces the material's yield strength and increases the bend radius required to form it.
    
    When working with thick steel plates, a common bend radius is 8 to 10 times the material thickness. For example, a 36 steel plate (0.30 in thick) requires a bend radius of at least 2.4 to 3 inches. A 45 steel plate (0.375 in thick) requires a radius of at least 3 to 3.75 inches. If cold bending is used, the bend radius should be at least two times the material thickness.
    
    The size of the radius also depends on the application. For example, the bend radius of a 36 plate used in welding applications is different than the bend radius needed when forming steel parts or components. Generally, the larger the radius, the higher the stress placed on the material, which can lead to cracking or fatigue over time. However, larger bend radii may be needed in certain applications to reduce the stress that could cause distortion or failure.
    
    When dealing with high strength steel alloys such as NM450, a larger bend radius is required. While a 36 steel plate bend radius typically ranges from 2.4 to 3 inches, NM450 steel plate requires a bend radius as high as 12 inches. This large bend radius is necessary because of the plate's higher strength and resistance to cracking.
    
    The bend radius is a critical factor when working with steel plate, as it affects the strength, fatigue resistance and cost of the end product. Understanding the bend radius needed for the application can help to ensure the project is successful. This is especially important when working with higher strength alloys such as NM450, where a larger bend radius is needed to reduce distortion and cracking.
