Bending 304 stainless steel sheet.

The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. 304 stainless 16 gauge bent on a van mark sheet metal brake. Slide the marked stainless steel sheet under the clamping leaf align the two center marked bending locations with the pivot line of the lower bending leaf and pull the clamping leaf handles toward you to lock the stainless steel sheet in position.

Like many other fabrication methods for stainless steel bending can be done using the same equipment used to bend other metals. A difference is that working hardening rates may mean a need for more rigid equipment and higher power levels. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. To help you begin i ve included a k factor chart below which contains common k factor starting points good for general fabrication for steel aluminum and stainless steel.

In the same situation the spring back of 304 stainless is 2 less than 301 stainless steel. It is possible to choose other bends if you require but additional lead time and tooling charges may apply. Step 3 pull the bending handles of the bending leaf up to bend the stainless steel sheet. Bend radii minimum bend sizes.

Because ss 304 contains 18 chromium cr and 8 nickel ni it s also known as 18 8 stainless steel type 304 has good processability weldability corrosion resistance heat resistance low. Aisi 304 grade stainless steel uns s30400 aisi 304 stainless steel uns s30400 is the most commonly used material in stainless steels and is usually purchased in an annealed or cold worked state. So i am looking for the parameters for 304 ss that will have the same outcome. The larger the ratio the larger the rebound the spring back of sus301 stainless steel is bigger than sus304 stainless steel.

Bending of stainless steel. And by that i mean the cut out prior to bending comes out to the right size. For instance right now in solidworks for say 11 ga sheet metal i use a bend radii of 0 005 and a k factor of 0 275 and that seems to work pretty well when i put the flat views on my prints. These are vent stack covers for a tankless hot water exhaust system.
