ASTM A36 steel plate thickness tolerance is according to ASTM A6/A6M standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. Flatness tolerance is always less than the dimensional tolerance associated with it. Tolerance under specified thickness .010" x 3/4 x 52" wide plate, for example, would have a tolerance range of .740 .780" Because of tolerances, ie thickness, flatness and camber, as well as the hot roll condition, ASTM A36 generally does not finish to specified thickness. Speedy Metals Information for Hot Rolled Carbon Steel Plate. Tolerances Illustrated steelwise October 2006 By understanding and accommodating structural steel production, fabrication, and erection tolerances, you can avoid expensive and time-consuming fi eld fi xes. Below is the Tolerance for Flatness taken from ASTM A480 (Understand that this covers Mill Plates and not cut pieces) Table A2.20 Permitted Variations in Flatness of Plate Mill Plate (Quarto Plate) %%EOF PGI Steel is "The Single Source Solution for Custom Steel Plate. Waterjetting 4" A36 Plate; Likes: 14. Up thru 48: Over 48 to 60, excl. * Thickness is measured along the longitudinal edges of the plate at least 3/8 in. One example of measuring flatness: A part is place on three reference blocks resting on a granite table. Career Portal Español. Permissible variations for structural shapes and plates as re-ceived from the mill are established in ASTM A6/A6M Section 12. This abstract is a brief summary of the referenced standard. Produced from an aluminum-magnesium alloy, the ATP-5 Plate works especially well in the high-volume cutting envir… A36 Steel plate has a 36,000 min yield strength. %PDF-1.6 %���� Choose from our selection of grade A36 steel, including low-carbon steel sheets and bars, tight-tolerance low-carbon steel bars, and more. A36 is considered a mild steel due to it’s relatively moderate hardness. The mill tolerances on pipe are readily available but there appears to be no reference to mill tolerances on plate. Contact CHAPEL STEEL. Our Response to COVID-19 . Spec. 1.1 Flatness is a significant quality characteristic of steel sheet products. May have multiple specs certified on Mill Test Report, but guaranteed to be certified to meet ASTM A36. Although ASTM is the most widely used specification for flatness, some products have developed their own flatness specs, so a review of the spec you are using is advised. Category B, C, D Tolerance Zone: The flatness tolerance zone is the volume between two parallel planes. This flatness guide is for reference only. Contact Us; Order. U-SQA A 5.25 (Ordering Code) B 3.00 T 0.50 BC 2.75 Type A B T The part number consists only of the fields with blue characters. Plate flatness is measured relative to a reference surface such as a grinder table or granite table. System of Measurement; Inch: Metric: Thickness. Steel plate is processed by flame cutting or High Def Plasma cutting. Potentially, the RMS could be as low as 15, making it an ideal figure for applications that require flatness and precision. If flatness is critical, please contact our sales team. ASTM A36 steel plate thickness tolerance: Because of tolerances, ie ASTM A36 steel plate thickness tolerance, flatness and camber, as well as the hot roll condition, ASTM A36 steel plate generally does not finish to specified thickness. Spec. Steel Plate. 0 Several factors may affect flatness – thickness, shape, grade and others. Also, should it be a finite figure or a percentage as per pipe? Sec.

Tolerance under specified thickness .010" x 3/4 x 52" wide plate, for example, would have a tolerance range of .740 .780" Because of tolerances, ie thickness, flatness and camber, as well as the hot roll condition, ASTM A36 … Each piece of metal has its own uniqueness. Tolerances for the dimensions of sheet and strip coils are specified. Flatness tolerance is always less than the dimensional tolerance associated with it. Length Length tolerances for plates are given in Table 3: Table 3: Tolerance over width and length for sheared edges Nominal length l (mm) Tolerances on the width Lower Upper l < 4000 0 +20 4000 ≤ l < 6000 0 +30 6000 ≤ l < 8000 0 +40 8000 ≤ l < 10000 0 +50 10000 ≤ l < 15000 0 +75 4.

A36 .068 - .750 96 CQ .068 - .750 96 .068 min - .750 max 24 min - 96 max 44” - 60 ft TOLERANCES CCP FLATNESS TOLERANCES -Carbon and HSLA steel with specified minimum yield thru 80,000 psi. The flatness tolerance references two parallel planes (parallel to the surface that it is called out on) that define a zone where the entire reference surface must lie. The flatness variations across the width should not exceed the tabular amount for A36 is one of the most widely used grades of steel plate. The A36 standard was established by the standards organization ASTM International. one of the popular and widely used carbon structural steels which is mild and hot rolled For all plates, the longest dimension is considered the length, and flatness tolerance along the length should not exceed the amounts indicated below the specified width and thickness in plate though 12' in length or longer.
