NOTE 3—Blank spaces in the tolerance tables indicate either that the material generally is not available or that no tolerances are established.
ASTM B249/B249M – 18a
In the event of conflict between this specification and the individual casting product specifications, the requirements of the casting specification shall take precedence. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. This standard is not included in any packages.
Within the text the SI values are given in brackets. Tolerances, Plus and Minus,A in. Table 5—Tolerances for diameter or distance between parallel surfaces of as-extruded rod and bar applicable to Speci? C and C Forgings and Extrusions. Over 2 to 4 Incl 0. One specimen from each piece shall be tested without further treatment, and the other specimen shall be tested after precipitation heat treatment. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Diameter or Distance Between Parallel Surfaces, in. Table 6—Diameter tolerances for hot-rolled round ast, applicable to Speci? A number in parentheses indicates the year of last reapproval. Preparation for Delivery S4.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. When so ordered, the edge contours described in 6. NOTE 1—The length tolerances in this table are all plus; if all minus tolerances are desired, use the same values; if tolerances are desired plus and minus, halve the values given.
In the case of copper-beryllium alloy, two specimens shall be taken for each required test. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
Alternatively, a lot shall be the product of one cast bar from a single melt charge, or one continuous casting run whose weight does not exceed 40 lbs [20 kg] that has been continuously processed and subject to aetm at one time. Materials shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional mass, diameter, length, straightness, and edge asgmmechanical tensile strength, Rockwell hardness, elongation, and hydrogen embrittlementelectrical resistivity, chemical composition, and grain size requirements.
Subscription pricing is determined by: You may delete a document from your Alert Profile at any time.
Expressed to the nearest 1? Samples of the rejected product shall be taken in accordance with the product speci? Your Alert Profile lists the documents that astk be monitored. C, C, and C Packaging and Package Marking To determine compliance with this paragraph, shafting shall, in case of disagreement, be checked by the following method: This standard is subject to asfm at any time by the responsible technical committee and must be reviewed every?
They are usually 10 or 12 ft [ or mm] and subject to established length tolerances. Rounded Unit for Observed or Calculated Value.
Products shall be manufactured by hot working, cold working, or both, and finished by cold working, annealing, or heat treatment and straightening as identified necessary to meet the properties specified. Limits may be established and analysis required for unnamed elements by agreement between the manufacturer or supplier and the purchaser. The tolerance on the radius shall be one fourth the thickness of the bar.
Materials and Manufacture 4. They are subject to minimum length and maximum weight requirements. Cand B
