Stainless Steel Flat Bars Stainless Steel Flat Bars Supplier Stainless Steel 304 & 316 flat bars are one of the most commonly requested products we supply, with other grades available. We provide stainless steel flat bars Sheared and True Mill. When you need quick delivery, custom lengths, or sizes, contact us. Our purchasing team has years of experience to make sure we supply the most competitive polished stainless steel flat bar product for your projects. The difference between a true mill flat bar and sheared or flat bar cut from the plate is dimensional tolerance. In the true stainless steel flat bars, tolerances for width and thickness are restrictive and have the better finish. In cutting the bar from the plate, the diametrical tolerance will be more generous and in line with the cutting method. The thickness of the flat bar cut from the plate will be the same as that of the HARP plate. Plate thickness tolerances tend to run on the heavy side. The minimum under tolerance for plate thickness is 0.010”, while the over tolerance is either unrestricted or is at least 0.090” and increases with thickness. Stainless Steel Flat Bar A stainless steel flat bar is rectangular shaped and manufactured through hot rolling, cold drawing, or cut from a plate. It’s rectangular-shaped and comes in varying width and thickness. These are ideal in applications where greater strength and durability are needed. It can also resist corrosion, making it a popular choice in various harsh industries such as construction, automotive, and aerospace. The Types of Manufacturing Stainless steel flat bars are available in two manufacturing processes: True Bar or Cut from plate. Both have distinct tolerances and differences, so identifying what sets them apart is imperative for your projects’ success. Hot Rolled Hot Rolled – To shape stainless steel, they need to be at above 1325-1500 degrees Celsius. This is above the temperature at which steel solidifies. For sculpting, mills shape and form the stainless steel flat bars easily at this temperature and can mass produce the material to our strict specifications. True Mill True Mill – True Mill and cold rolled is an added step to the hot rolled process. It does create a better piece of stainless steel flat bar material, but it also takes a lot longer to create cold rolled over hot rolled. While hot rolled materials are produced and shipped out, cold rolled materials are sent over to cooling plants where they are then annealed, or temper rolled. This will press the material into finer dimensions without losing any of the density. This concentration allows the material to be able to withstand equal or sometimes more concentrated force while also taking less room. It also has a tighter tolerance than a Sheared and Edge. Difference Between Plates and Sheets and Flat Bars There is a fine line between stainless steel sheets and stainless steel plates. That line is the amount of thickness involved. We will often receive orders for sheet metal that should clearly be a plate and vice versa, so to clear that up, here is a disclaimer. Stainless Steel Sheet – Sheet is available in a thickness less than .250″- .018” thick. Stainless sheets are usually ordered by gauge thickness, width, and length. Width starts at 48” wide and length can be 144” long. Custom width and lengths available upon request. Stainless Steel Plate – Plates are when the thickness of the metal are thicker than 3/16″ to 6″ which may have a #1 HRAP finish. Plate starts at 48” wide and the length can be 30’ long. We offer custom sizes. Stainless Steel Bars – Stainless steel bar stock is often produced in different grains than plates and sheets and are not as wide. The width or length of the bar is what would determine a flat bar to be qualified as a plate or bar. True mill flat bar – Tolerances for width and thickness in these stainless steel flat bars are restrictive and have sharper edges. The finish on all four sides of the will be the same and will have a smoother finish and less twist. Sheared flat bar – We can offer Sheared stainless steel flat bar from plate. Need special lengths just ask we can offer 20’ length with a quick turnaround. The width tolerance will be greater with one edge having a slightly rounded radius. The material will have a hot rolled finish, not all sides will have a uniform finish. The side was material cut would vary. Flat bars cut from plate can meet ASTM A276, and A479 is permitted via ASTM A484. Special finishes available, 180 Grit and higher, Call today. Cold Drawn Flat Bar – Cold Drawn Stainless Steel Flat Bars are available in 303 Stainless Steel. Call us now to request more information for width, thickness and restrictions. Limited quantities of the stainless steel flat or square bar are produced in several alloys where they are in demand for aerospace applications or where cutting from the plate is prohibited. This includes titanium alloys and PH 15-5.
