304L polished Stainless bent steel pipe rust marks in 2 weeks
We are now getting into bending stainless steel pipe, and we build some bent pipe bollards using 304L Stainless steel. Our customer requested a polished shiny surface finish, therefore we brushed them and then we polish them with polishing component to a shiny bright look. After we shipped this to our customer in the USA, 2 weeks after, he called us complaining that there was some tiny brownish stain marks on the surface, therefore complaining to us that the steel was rusting, but expecting bending stainless steel conduit polishing Bending Stainless Steel Conduit Polishing - Image ResultsDue to high ductility, annealed austenitic stainless steels can be bent to equally small bend radii, gauge for gauge, as carbon steel. Dies should be given a high polish and be free from all surface blemishes to prevent marring the stainless steel finish. The power necessary to bend annealed stainless steel is 50 to 60 percent more than is needed for carbon steel. All metal spring-back, or elastic recovery, and 300 series stainless conduit has about 5% more than galvanized steel.

Bending Stainless Steel Tubing: A Few Considerations - The bending stainless steel conduit polishingA variety of methods can be used for bending stainless steel tubing. If the bend has a large radius, the tubing can be curved with three-roll benders (also called section benders, profile benders, or angle rolls.) If the bend has a tight radius, the tubing can be bent on a rotary-draw bender through a process called mandrel tube bending.

You could use pre-formed hygienic stainless tube bends and butt weld to the tube you have. Ive done this with good success on 11/4, 1 and 3/4 polished tube. I polished the bends prior to welding. Obviously the welding and acid pickle will tarnish the polished finish but can be re-polished afterwards.

Cutting, Threading, and Bending Instructions for Stainless bending stainless steel conduit polishing
Stainless steel can be bent using a standard rigid conduit bender, but exercise caution, as there can be a greater degree of springback in stainless pipe. This is especially true for larger stainless steel rigid conduit sizes, 2 or larger. a. Hand benders are suitable for conduit sizes to 1. b. Power or mechanical ratchet benders are Finishing stainless steel - The FabricatorIt is obtained by mechanically polishing a No. 3 finish with gradually finer abrasives. Depending on the requirements of the application, the final finish can be anywhere between 120- and 320-grit. Higher grit numbers produce finer polishing lines and more reflective finishes. The surface roughness is typically Ra 25 in. or less. How To Bend Stainless Steel Pipe - Beall Industry GroupAt present, there are two ways to make the stainless steel pipe bend on the market: 1.Cold bending method for stainless steel pipe bending: generally, the bending machine is used for rolling forming for many times. Disadvantages: the diameter of steel pipe is limited, generally only between 1cm-5cm; if the curvature is too small, the diameter bending stainless steel conduit polishing
