Our precision saws provide fast and tight tolerance cuts. The cutting method will determine whether there is any twist or camber. Stainless steel true bar is a rolled edge bar flat in Type 304, and comes in 12' lengths. Compared with other stainless steel alloys, 304 is an optimal choice for dealing with corrosive environments and within heat-affected zones. This bar has fairly sharp corners and tighter tolerances on thickness and width than sheared and edged and is often used by fabricators where the finished project is polished. A | ASME SA-479 Cond. Stainless Steel Flat Bar 304/304L can often be used in place of Plate when not specified on a project. Squareness of Legs:The tolerance for the right angle between the legs is +/- 2 degrees. To produce true flat bar, a process known as Hot Rolled Annealed and Pickled (HRAP) is generally employed, which results in a gray finish. With a variety of grades, including 15-5, 17-4, 303, 304, 316, 410 and 416, our stock lengths can be customized for your applications by sawing, punching, drilling, milling, welding, and bending. Stainless Steel T-304 True Mill flat bar is drawn through a pre-formed die. Lbs. Width governs the tolerances both width and thickness for rectangle bars. 303 stainless steel flat bars are used for parts that need to be polished, ground or machined, and that have to be corrosion-resistant. Choose from our selection of stainless steel true bar, including multipurpose 304 stainless steel, corrosion-resistant 316 stainless steel, and more. Tight-Tolerance Wear-Resistant 410 Stainless Steel. Tolerance values given in microns = x0.001 mm. The surface finish on the sides will vary on cut bar compared to the bottom and top, which will be the original plate surface. One Chicago Tube Drive , Romeoville, IL 60446. At the same time, the nickel content means that it is resistant to organic acids. Precision ground steel bar is suited for applications which require a tighter tolerance than standard commercial bright drawn, bright turned or bright peeled bar. When the bar is cut from plate, the guidelines for width tolerance are not as strict and depend more on the cutting method. 304 steel does not offer much electrical or thermal conductivity but does have a higher corrosion resistance than regular stainless steel and is recognized for its formability. Sizes Product Sizes. The generally permitted variation range is 1/8”. ... Also called flat stock, these precision-ground bars are held to tight thickness and width tolerances. This stainless steel alloy was originally developed by Firth Brown Steels in 1924 and was first sold under the trademark Staybrite 18/8. Per Sheet; 1/4: x: 1/2.4250: 5.100; 5/8 Standard Tolerances For Stainless Steel Usually, choosing material thickness is one of the first steps a designer takes when starting a project. EN 10058 - Stainless Steel Flat bars Width and thickness must be measured at least 100mm from the end of the bar. A Standard Lengths: 12 Ft. Random. Shop a precision stainless steel blank assortment in squares and rectangles that have guaranteed tolerances and are machine ready, so they increase throughput by reducing your prep and setup time. In addition, a carbon maximum of only .03 percent means that it is ideal for welding operations under 800 degrees F. While heat treatment is not an option, cold working can be performed to make the material both harder and stronger. That’s why 304 is often used in sinks, tabletops, coffee pots, stoves, refrigerators, and liquid dispensers. The chromium content of 304 flat bar increases its corrosion resistance in oxidizing environments. 0.008 0.008 0.012 Over 7/8 to 1 incl. 409 is especially useful for applications requiring oxidation or corrosion protection beyond the capability of carbon steel and some coated steels. Type 316/316L stainless is 304/304L modified with the addition of Molybdenum. In cutting bar from plate, the width tolerance will be … For angles having legs or flanges up to 6″ incl., the length tolerance shall not exceed +/- 1/8″. True bar will provide closer tolerances and a true 90 degree corner. Other alloys can be provided upon request. (Identical with Table #11 of ASTM A484) Measurement is taken on the concave side of the bar with a straight edge. Stainless Steel Flat Bar. A Standard Lengths: 12 Ft. Random. The prevalent alloying agents in 304 steel are chromium (at around 18%) and nickel (around 8%). SAE 304 stainless steel, otherwise referred to as A2 stainless steel or 18/8 stainless steel, is the most widely used stainless steel alloy on the market. A | ASTM A 276 Cond. A flat bar is considered to be true when it is produced to a specific size and has a nearly identical finish on all four sides. 316/316L True Mill Flat Stainless Steel Bar. The standard should be consulted for tolerances beyond the size and class range of this table and for other letter tolerances. Sandvik's program of hollow bar includes several grades of austenitic stainless steel as well as duplex stainless steel. The thickness of bar cut from plate is determined by the thickness of the plate. Tolerances are for shafts as per AS 1654.2 – 1995 / ISO 286-2:1988. A | ASTM A 276 Cond. 304 alloy is prized for its versatility, the reason why it is so popular for manufacturing applications. Stainless Steel Bars Penn Stainless Products offers stainless steel bar products, including stainless steel round bar, hex bar, square bar, rolled flat bar, half rounds, and more. Weight:For angles of 6 lb/ft or less, the weight tolerances shall not exceed +/- 7-1/2%. 409 has good oxidation resistance and formability, but lower corrosion resistance due to the chromium content. Examples 25.40mm diameter bright drawn bar to h9 tolerance = +nil, -0.052mm 90mm diameter peeled bar to k12 tolerance = +0.35mm, -nil Reference A ASTM A 479 Cond. Pickling is a method in which the metal is placed in an acid solution in order to get rid of any high-temperature oxides that generally are seen after annealing or welding. For angles over 6 lb./ft, the weight tolerances shall not exceed +/- 4-1/2%. True flat bar is usually in the HRAP condition, though it may sometimes be cold drawn. Flat Bar allows for tighter tolerances to get you closer to the exact size you need. The edges of the flat bars are closer to a true 90 degree angle and are sometimes referred to as “ true mill bar”. In contrast, the process of producing sheared bar involves cutting the bar from stainless steel plate. The primary difference between true flat bar and flat bar cut from plate is dimensional tolerance. tOLeRAnceS StAinLeSS BARS SiZe tOLeRAnceS — HOt ROLLed ROUndS And SQUAReS Size tolerance, inches Out-of-Round Specified Size Over Under Out-of Square inches Section, inches1 Over 5/16 to 7/16 incl.2 0.006 0.006 0.009 Over 7/16 to 5/8 incl.2 0.007 0.007 0.010 Over 5/8 to 7/8 incl. 409 is a general purpose stainless steel with 11% chromium. As an austenite steel, 304 is non-magnetic in nature and its eutectoid point occurs at 727 °C (1,341 °F). For example, 25.40mm diameter bar to h9 = + Nil, -0.052mm. Opt for stainless steel stock including stainless steel blanks, flats, bars, plates and sheet stock from Grainger to help improve your firm’s productivity. Non-Magnetic* Annealed and Pickled QQ-S-763 Cond. The standard mentions the shapes round, hexagon, square and flat, but not all of these cross sections have specific tolerance tables. For angles over 6 lb./ft, the weight tolerances shall not exceed +/- 4-1/2%. 6270 Van Buren Road Wayne State Warrior race team – Future Engineers! Clinton Aluminum | All rights reserved. 304 stainless steel is widely found in a variety of household applications. 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. Categories: Bar, Flat, Stainless Steel. Flats produced in this manner have closer tolerances. Because of its greater cost, only limited quantities of true flat bar tend to be produced, such as for demanding applications in the architecture and aerospace industries, unless there is a large enough quantity required to justify it.
