Stainless Steel Sheet Metal Bend Radius Chart

Divide 50 by the material s reduction percentage as specified by the material supplier subtract by 1 and then multiply by the plate thickness.

Stainless steel sheet metal bend radius chart.

The minimum bend radius data shown in these charts is measured to the inside of the bend. 22 gauge 0 030 0 76 mm. You described a rough rule to find a steel s minimum bend radius. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.

Bottoming as the name bottom pressing suggests the punch presses the metal sheet onto the surface of the die so the die s angle determines the final angle of the workpiece. An air bend force chart or force chart breaks down a number of key components of sheet metal bending in an easy to reference format. Microform precision llc 4244 south market court suite a sacramento ca 95834 phone. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.

The following tables showing the minimum bend radius allowable in air bending process for aluminum and steel or stainless steel. A general guideline the minimum metal bend radius is approximately equal to the material thickness. The gauge inside radius die opening and minimum flange length are all interconnected through different equations and relationships the air bend force. Being able to read a bend force chart is crucial for any brake press operator and sheet metal engineer.

Table 1 preferred recommended 90 degree bend radii for various sheet metals. Since commercial sheet metal bending can be done with less concern for stresses caused during forming operation the radius can be near zero for thin sheet metal. Aluminum 5052 or 3003. The opposite happens with stainless steel the required force is 1 7x higher than the ones displayed in this table.

It is possible to choose other bends if you require but additional lead time and tooling charges may apply. 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. 22 gauge 0 030 0 76 mm 0 5 12 7mm. The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance.

The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. Category thickness minimum bend bend radius.
