Bend Radius Sheet Metal Stainless Steel Metric

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

Bend radius sheet metal stainless steel metric.

Recommended minimum bend radii for steel and aluminum. The bend deduction sometimes called the bend compensation describes how much the outside of the sheet has been stretched. It is possible to choose other bends if you require but additional lead time and tooling charges may apply. The minimum bend radius data shown in these charts is measured to the inside of the bend.

We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. Discover all our calculation tools in the calculators section of the top menu. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. Divide 50 by the material s reduction percentage as specified by the material supplier subtract by 1 and then multiply by the plate thickness.

22 gauge 0 030 0 76 mm 0 5 12 7mm. The bend allowance added to the flange lengths is equal to the total flat length of the part. Therefore the bend deduction equals the difference between the mold line lengths and the total flat length. 22 gauge 0 030 0 76 mm.

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. When the sheet metal is put through the process of bending the metal around the bend is deformed and stretched. As this happens you gain a small amount of total length in your part. Understanding the bend allowance and consequently the bend deduction of a part is a crucial first step to understanding how sheet metal parts are fabricated.

To get the best results a design engineer has to account for many factors such as the end use of the metal form the material the sheet metal is made of plain steel stainless steel etc and the dimensions shape of the final product. Microform precision llc 4244 south market court suite a sacramento ca 95834 phone. This tool allows you to determine tonnage internal radius v die opening and minimum flange you just have to insert the characteristics of the sheet metal to be bent. Sheet metal bend radii if these guidelines are not followed more research and or some form of analysis may be requried.

Making a custom metal form using sheet metal is a surprisingly delicate process. Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t. 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.
