Bending 304 Stainless Steel Sheet

We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.

Bending 304 stainless steel sheet.

It is possible to choose other bends if you require but additional lead time and tooling charges may apply. In the same situation the spring back of 304 stainless is 2 less than 301 stainless steel. Like many other fabrication methods for stainless steel bending can be done using the same equipment used to bend other metals. 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.

304 stainless 16 gauge bent on a van mark sheet metal brake. Shot with the sony a7rii in 4k with a sigma 18 35mm art lens. So i am looking for the parameters for 304 ss that will have the same outcome. Bend radii minimum bend sizes.

It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. Step 3 pull the bending handles of the bending leaf up to bend the stainless steel sheet. A k factor will typically range between 0 and 5 for standard materials and thicknesses though smaller and larger k factors are possible. 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.

Equally equipment capacity will be much lower than for carbon steels. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. 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. A difference is that working hardening rates may mean a need for more rigid equipment and higher power levels.

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. These are vent stack covers for a tankless hot water exhaust system. The larger the ratio the larger the rebound the spring back of sus301 stainless steel is bigger than sus304 stainless steel. 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.
