If you want a sharp 90 bend tap along the crease with a mallet.
Bending 22 gauge spring steel sheet.
Finally bend the sheet up by hand to the angle desired.
22 gauge 0 030 0 76 mm 0 5 12 7mm.
Mark a bend line and place the sheet metal on the edge of your bench.
Clamp the wood on top of the metal to the workbench.
These sheets have a softened temper which is also known as annealed so they can be easily formed into shape and then heat treated for.
Category thickness minimum bend bend radius.
For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.
Spring steels are known for their high yield strength which allows objects made of spring steel to return to their original shape after bending and forming.
Tempered spring steel is commonly referred to as high carbon steel and is useful for a number of applications including.
Our offerings also include.
Gauge and weight chart for sheet steel galvanized steel stainless steel aluminum and strip tubing sponsored links wire gauge is a measure for the size of a wire either in diameter or in cross sectional area.
Metal shops have brakes mounted at different angles with automated braking arms however it is possible to bend sheet metal at home without the use of a brake.
Next place the wood parallel and slightly behind the bending line.
0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance keep in mind that some metals are more brittle than others.
You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k.
As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be.
The minimum bend radius data shown in these charts is measured to the inside of the bend.
The material thickness will be measured in decimal form not by the gauge number.
Blue tempered and polished spring steel.
Gauges are neither standard nor metric and the values are independent of those measurement systems.
A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.
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.
The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance.
When working with sheet metal one particularly useful piece of equipment is the brake.
The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
