For angles having legs or flanges over 6″, the length tolerance shall not exceed +3/16″ / and -1/8″. Our stainless steel flat bar, available in 304 and 316, is stocked as annealed and pickled, … 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″. This material is precision ground to offer tighter tolerances than standard 316 stainless steel. A true flat bar is usually in the HRAP condition though it may sometimes be cold drawn. Clinton Aluminum | All rights reserved. Our precision saws provide fast and tight tolerance cuts. This is especially true when working with stainless steel alloys such as 304. When it comes to the edges and corners, as previously mentioned, it will be nearly identical on all four sides in true bar. In contrast, the process of producing sheared bar involves cutting the bar from stainless steel plate. Action Stainless stocks sheared and edge conditioned flat bar in grades 304 and 316. When it comes to the most common grades of stainless steel flat bar such as 304L and 316L, there are two basic ways these bars are produced – sheared and edged bar, and true flat bar. 409 has good oxidation resistance and formability, but lower corrosion resistance due to the chromium content. These are summarised below. Wayne State Warrior race team – Future Engineers! Tolerance values given in microns = x0.001 mm. A Standard Lengths: 12 Ft. Random. 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. The cutting method will determine whether there is any twist or camber. 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. The generally permitted variation range is 1/8”. 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. Length of Legs:For angles having legs or flanges up to 6″ incl., the length tolerance shall not exceed +/- 1/8″. Tolerances are for shafts as per AS 1654.2 – 1995 / ISO 286-2:1988. stainless steel rod/bar rectangular 304/304l qqs-763 .5000 x 2.0000 Opt for stainless steel stock including stainless steel blanks, flats, bars, plates and sheet stock from Grainger to help improve your firm’s productivity. Clinton Aluminum, Inc. The standard should be consulted for tolerances beyond the size and class range of this table and for other letter tolerances. In marine environments, it is common to find 304 used for nuts, bolts, screws, and other types of fasteners. 304 alloy is prized for its versatility, the reason why it is so popular for manufacturing applications. To draw, is to “pull through”. A ASTM A 479 Cond. All transactions are subject to the Company’s current Conditions of Sale. 6270 Van Buren Road All stainless rolled flat bars are stocked in standard 12’ random length sections. A | ASME SA-479 Cond. True flat bar is usually in the HRAP condition, though it may sometimes be cold drawn. 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. With square corners, the tolerances are within a few thousandths of an inch to the listed dimensions. 409 is not as corrosion resistant as 304, 430 or 439 grades, but far superior to mild carbon … As an austenite steel, 304 is non-magnetic in nature and its eutectoid point occurs at 727 °C (1,341 °F). This includes kitchen benches and troughs, the common coils in vaporizers, screws, automobiles, and water filtration devices. Wear-Resistant Stainless Steel. Machining Allowance. A | ASME SA-479 Cond. Standard Tolerances For Stainless Steel Usually, choosing material thickness is one of the first steps a designer takes when starting a project. A ASTM A 479 Cond. Other alloys can be provided upon request. Examples 25.40mm diameter bright drawn bar to h9 tolerance = +nil, -0.052mm 90mm diameter peeled bar to k12 tolerance = +0.35mm, -nil Reference Flat Bar allows for tighter tolerances to get you closer to the exact size you need. Squareness of Legs:The tolerance for the right angle between the legs is +/- 2 degrees. Categories: Bar, Flat, Stainless Steel. We work with nominal thicknesses, so it's important to know the thickness tolerance on the material you chose, in order to know if … Sandvik's program of hollow bar includes several grades of austenitic stainless steel as well as duplex stainless steel. Per Square Foot Est. A | ASTM A 276 Cond. 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. One Chicago Tube Drive , Romeoville, IL 60446. 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. A true flat bar is produced at the mill to the specific size indicated. We also stock 303 in cold finished flat bars. The chromium content of 304 flat bar increases its corrosion resistance in oxidizing environments. The edges of the flat bars are closer to a true 90 degree angle and are sometimes referred to as “ true mill bar”. 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. Look to Ryerson for stainless steel bar in flat, half round, hexagon, round and square forms. To produce true flat bar, a process known as Hot Rolled Annealed and Pickled (HRAP) is generally employed, which results in a gray finish. This is because of the significant price difference between the two. 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. Weight:For angles of 6 lb/ft or less, the weight tolerances shall not exceed +/- 7-1/2%. In true flat bar, tolerances for width and thickness are restrictive and more or less mirror those established for round bar. The main difference between true flat bar and flat bar that was cut from plate and then sheared is the dimensional tolerance. 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. 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. 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. For example, 25.40mm diameter bar to h9 = + Nil, -0.052mm. Per Sheet; 1/4: x: 1/2.4250: 5.100; 5/8 The standard mentions the shapes round, hexagon, square and flat, but not all of these cross sections have specific tolerance tables. Tolerances for bright drawn, ground, turned and polished stainless steel bars are included with the general standards for other bright steel bars in BS EN 10278. Tight-Tolerance Wear-Resistant 410 Stainless Steel.
