If you want a 90 box (ie… flat w/ 4 sides bent up 90 at a certain desired height), you should use edge flanges. So, if the metal plate is .75” thick, you would multiply 4 x .75 = 3, so your minimum inside bend radius would be roughly 3 times the thickness of the material in this case, or 2.25”. The nice thing with flanges, your flat pattern will include the extra material required for bend deformation. Specifing a bend radius from here will help prevent hair line cracks. Aluminum is less forgiving than cold-rolled steel or stainless steel. So in this case, the minimum inside bend radius is 2 times the material thickness. Bending of stainless tube can be difficult unless done by persons experienced in the field. 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. Recommended minimum bend radii for steel and aluminum. Typically, you need the K-factor to match your own capabilities. I am assuming the bend radii and k factor would be different for a SS since it is harder than regular sheet metal. So we bend a lot of mild steel. endstream endobj 1097 0 obj <. There are inside bend radius recommendations listed for some of the steel grades that we stock. In some instances Type 304 can be used in the "as-welded" condition. We bend lots of stainless, which in terms of hardness, is very similar to mild steel (a36/gr50/cq) If I were to start folding, I would use .125 and a K-factor of .45 Maximum sheet thickness for aluminum is 8 mm. 1135 0 obj <>stream There are two ways to bend stainless steel rod, one requires force and the other requires heat.

In general mild steel and type 304 stainless sheet can be formed with sharp bends (< 1T) without concern up to 1/8" thick. If you have a picture or hand sketch, I could be more specific. Below 1.5D is short radius elbow, and more than 1.5D but not over 2D is long radius elbow. Minimum Bend Radius Stainless Steel Tubing Video. If you want a 90 box (ie… flat w/ 4 sides bent up 90 at a certain desired height), you should use edge flanges. So, if the metal plate is .75” thick, you would multiply 4 x .75 = 3, so your minimum inside bend radius would be roughly 3 times the thickness of the material in this case, or 2.25”. The nice thing with flanges, your flat pattern will include the extra material required for bend deformation. Specifing a bend radius from here will help prevent hair line cracks. Aluminum is less forgiving than cold-rolled steel or stainless steel. So in this case, the minimum inside bend radius is 2 times the material thickness. Bending of stainless tube can be difficult unless done by persons experienced in the field. 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. Recommended minimum bend radii for steel and aluminum. Typically, you need the K-factor to match your own capabilities. I am assuming the bend radii and k factor would be different for a SS since it is harder than regular sheet metal. So we bend a lot of mild steel. endstream endobj 1097 0 obj <. There are inside bend radius recommendations listed for some of the steel grades that we stock. In some instances Type 304 can be used in the "as-welded" condition. We bend lots of stainless, which in terms of hardness, is very similar to mild steel (a36/gr50/cq) If I were to start folding, I would use .125 and a K-factor of .45 Maximum sheet thickness for aluminum is 8 mm. 1135 0 obj <>stream There are two ways to bend stainless steel rod, one requires force and the other requires heat. The tight radius bend allows you to get into the awkward angles. I'm Working on a design that involves using 304 SS (1/8" thick). A general guideline, the minimum metal bend radius is approximately equal to the material thickness. Maximum dimensions are 2980 x 1200 mm. (this also moves the liability from the designer to the fabricator). Maximum sheet thickness for stainless steel is 6 mm. Our bend radius rule of thumb is the minimum radius = material thickness. R is radius of curvature; D is (elbow or bend) pipe diameter. These dimensions are all in relation to a 90° angle. When the desired radius is very tight, seamless usually bends better. You can also choose from 300 series minimum bend radius 304 stainless steel sheet, as well as from sgs, iso minimum bend radius 304 stainless steel sheet, and whether minimum bend radius 304 stainless steel sheet is jis, astm, or aisi. As one of the leading Stainless Steel U Bolt manufacturers we produce the bolts in different grades of the material. If anyone has worked with 304 SS and the sheet metal bending features on solidworks and knows what these values should be...please let me know. Our bend radius rule of thumb is the minimum radius = material thickness. If you’re working with 304 stainless steel, multiply its median percentage value—21 percent—by the die opening. The email with your password reset link has been sent. Determining Minimum Bend Radius for Push-Pull & Pull-Pull Cables. So i am looking for the parameters for 304 SS that will have the same outcome. I was out yesterday, but YES! https://www.lehisheetmetal.com/engineering.htm. 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. In steel between 0.5 and 0.8 in. Recently we bent 8 pieces of 304 seamless stainless steel tubing 1.5 OD x 0.083 wall (14 ga) to a 5.25in inside radius with 81 degrees of arc and with 6in tangents on each end. You should not need to know the k factor for your part. The tool can calculate the required bending force for bending aluminum, stainless steel, mild steel, and Weldox® or Strenx® high-strength steels.. The minimum inside bend radius is even larger when bending with the grain. thick: 4 × 0.5 = 2. We bend lots of stainless, which in terms of hardness, is very similar to mild steel (a36/gr50/cq)  If I were to start folding, I would use .125 and a K-factor of .45, This is the most common way as each bending machine has its own unique bending factors but if you are doing it for your own company then the operator should bend some material and the give you the Details. Processes. I appreciate the help! 1096 0 obj <> endobj I will look more into the table and information you have given me. A wide variety of minimum bend radius 304 stainless steel sheet options are available to you, such as plate. Note that this is just a rule of thumb. Due to our lead times through our own shop, we have say a 50 piece order, we would do 3-5 sample pieces, hoping we could get the bend program correct before cutting all 50 pieces for the run. We have one customer, for which they actually bend a lot of the parts we are now doing for them. Being able to read a bend force chart is crucial for any Brake Press operator and sheet metal engineer. Tip: Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. However, it is important to know that this is just a broadly applicable rule of thumb you can follow for making bends in steel. ... some form of analysis may be requried. Table 1 Preferred recommended 90 degree bend radii for various sheet metals. Why Stainless Steel U Bolt should be formed after the threads are rolled? https://www.thefabricator.com/article/bending/k-factors-y-factors-and-press-brake-bending-precision, since different fabrication shops have different bending machinery with unique capabilities; always ask the fabricator which variables to use for their machines, and, send the fabricator the 3D bent part, and let them determine the flat pattern themselves, based on how they will make the part. Also depending on the manufacturers bend dies, etc the results may not be exactly the same as the resource above. Bend Radii & Minimum Bend Sizes .
