  • How to Bend Stainless Steel Sheets | Hunker

    Chromium and nickel give stainless steel its stain resistance and attribute to the hardness of the metal. This added hardness increases the amount of force needed to place a bend on a stainless steel sheet. As you bend a stainless steel sheet the bend area cold hardens, increasing the amount of pressure required to finish the bend.

    The bending radius must be at least 0.8 T to 2 T for sheet steel. Larger bend radii require about the same force for bottoming as they do for air bending, however, smaller radii require greater force—up to five times as much—than air bending. Advantages of bottoming include greater accuracy and .

  • Minimum versus recommended inside bend radius

    Q: In a previous Bending Basics article, you mention a "material's tensile reduction percentage" used for calculating the minimum inside bend radius of various metals. You described a rough rule to find a steel's minimum bend radius: Divide 50 by the material's reduction percentage, as specified by the material supplier, subtract by 1, and then multiply by the plate thickness.

    The inside bend radius that is developed during the air bending process depends on 3 factors: 1) the width of the vee die, 2) the stiffness of the material, and 3) the radius of the upper tool. The wider the vee die, the larger the resulting bend radius. The more ductile (easier to bend) the material, the smaller the resulting bend radius.
