Clinton Aluminum is the Midwest’s leading supplier of aluminum and stainless steel plate products. 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. Wayne State Warrior race team – Future Engineers! Hollow bar standard sizes range from outside diameter 20 to 420 mm (1.26 to 16.5 in. Flats produced in this manner have closer tolerances. Per Sheet; 1/4: x: 1/2.4250: 5.100; 5/8 Many kitchen utensils, such as pots, pans, and flatware, also benefit from 304’s high corrosion resistance. Contact a member of our knowledgeable and friendly staff today! 409 has good oxidation resistance and formability, but lower corrosion resistance due to the chromium content. 409 is a general purpose stainless steel with 11% chromium. *Thickness is meausred along the longitudinal edges of the plate or plate coils at least 3/8″, but not more than 3″ from the edge before the bar is cut or slit. These are summarised below. A ASTM A 479 Cond. This is because of the significant price difference between the two. A Standard Lengths: 12 Ft. Random. This is 2% per side on re-rolled round bar, taken from minimum permissible diameter. 304/304L True Mill Flat Stainless Steel Bar. For angles over 6 lb./ft, the weight tolerances shall not exceed +/- 4-1/2%. 303 stainless steel flat bars are used for parts that need to be polished, ground or machined, and that have to be corrosion-resistant. 0.009 0.009 0.013 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. 304 alloy is prized for its versatility, the reason why it is so popular for manufacturing applications. One Chicago Tube Drive , Romeoville, IL 60446. Gage and Size in … This is especially true when working with stainless steel alloys such as 304. 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. Plate thickness tolerances tend to run on the heavy side. Stainless Steel T-304 True Mill flat bar is drawn through a pre-formed die. For certain applications, such as architecture and aerospace, true bar is necessary because they require consistently polished surfaces on all four sides. The thickness of the flat bar cut from the plate will be same as that of the HARP plate. The standard should be consulted for tolerances beyond the size and class range of this table and for other letter tolerances. Because it has been edged, the resulting bar is not as dimensionally true as true flat bar, but it does undergo flattening and straightening that can approximate true bar. Squareness of Legs:The tolerance for the right angle between the legs is +/- 2 degrees. Precision ground steel bars can be supplied to a defined tight tolerance on diameter, providing good roundness, straightness and a fine surface finish. Wear-Resistant Stainless Steel. Clinton Aluminum, Inc. For angles having legs or flanges up to 6″ incl., the length tolerance shall not exceed +/- 1/8″. The edges of the flat bars are closer to a true 90 degree angle and are sometimes referred to as “ true mill bar”. All stainless rolled flat bars are stocked in standard 12’ random length sections. A ASTM A 479 Cond. Manufacturers understand the importance of selecting the right materials for a particular application. The cutting method will determine whether there is any twist or camber. To draw, is to “pull through”. A true flat bar is usually in the HRAP condition though it may sometimes be cold drawn. Not many people know that various acids can also be found in food, such as fruit, meat, milk, and vegetables. One of the major choices that manufacturers need to make when purchasing 304 stainless steel bar is whether they require true bar or sheared bar. A | ASME SA-479 Cond. True flat bar is usually in the HRAP condition, though it may sometimes be cold drawn. 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. EN 10058 - Stainless Steel Flat bars Width and thickness must be measured at least 100mm from the end of the bar. In stock and ready to ship. 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. First of all, it offers high corrosion resistance, even to intergranular corrosion, a kind of corrosion that is often the result of stress relieving or welding. Stainless steel true bar is a rolled edge bar flat in Type 304, and comes in 12' lengths. Sandvik's program of hollow bar includes several grades of austenitic stainless steel as well as duplex stainless steel. The prevalent alloying agents in 304 steel are chromium (at around 18%) and nickel (around 8%). DIMENSIONAL TOLERANCES FOR STAINLESS STEEL BARS FLAT BAR ( to ASTM A276 / A484M ) Width Width ( mm ) 3.2mm to 13mm < 13mm to 25mm < 25mm to 50mm Tolerance < 25mm + 0.008 + 0.010 + 0.015 - 0.008 - 0.010 - 0.015 25mm to 50mm + 0.012 + 0.015 + 0.031 + 0.031 - 0.012 - 0.015 - 0.031 - 0.031 < 50mm to 100mm + 0.015 + 0.020 + 0.031 + 0.062 Tolerances are for shafts as per AS 1654.2 – 1995 / ISO 286-2:1988. Stainless steel flat bar is divided into two primary groups – true flat bar and sheared and edged bar. We make it our top priority to work with our customers as a partner, meaning we will help you based on your specific product needs, even if we have to recommend a product or alloy we don’t carry. For angles of 6 lb/ft or less, the weight tolerances shall not exceed +/- 7-1/2%. For angles over 6 lb./ft, the weight tolerances shall not exceed +/- 4-1/2%. Gage and Size in Inches Lbs. (Identical with Table #11 of ASTM A484) Measurement is taken on the concave side of the bar with a straight edge. Stainless Steel round, hexagon and square bar - common uses and ISO tolerances 6270 Van Buren Road Categories: Bar, Flat, Stainless Steel. Stainless Steel: Hex Bar (Metric) 304, 316 Cold Finish >3mm to ≤6mm 0/-.075mm: Stainless Steel: Hex Bar (Metric) 304, 316 Cold Finish >6mm to ≤10mm 0/-.090mm: Stainless Steel: Hex Bar (Metric) 304, 316 Cold Finish >10mm to ≤18mm 0/-.111mm: Stainless Steel: Hex Bar (Metric) 304, 316 Cold Finish >18mm to ≤30mm 0/-.130mm: Stainless Steel: Hex Bar The chromium content of 304 flat bar increases its corrosion resistance in oxidizing environments. This stainless steel alloy was originally developed by Firth Brown Steels in 1924 and was first sold under the trademark Staybrite 18/8. Other alloys can be provided upon request. Machining Allowance. When working with metal, there have been so many advances in stainless steel and aluminum that even minute differences between alloys, or even between various shapes and extrusions, can lead to widely varying results when incorporated into modern day production processes. Buy quality stainless steel round bar tolerances products from stainless steel round bar tolerances manufacturer, 656 stainless steel round bar tolerances manufacturers & stainless steel round bar tolerances suppliers from China. Stainless Steel Flat Bar. It’s necessary to have a good understanding of the differences between them before making such a selection. Sizes Product Sizes. 316/316L True Mill Flat Stainless Steel Bar. Today, most stainless steel flat bar is sold sheared and gauered, rather than as true bar. Opt for stainless steel stock including stainless steel blanks, flats, bars, plates and sheet stock from Grainger to help improve your firm’s productivity. Pickling methods include immersing the steel in an acid solution bath, spraying it on the surface, or even by applying the solution with a paintbrush. Penn Stainless will also process all stainless rolled flat bar. In cutting bar from plate, the width tolerance will be … Non-Magnetic* Annealed and Pickled QQ-S-763 Cond. Industrial applications include machinery parts, food processing equipment, aerospace equipment, architectural uses such as exterior accents for water and fire features, the dyeing industry, chemical containers, and heat exchangers.
