In the case of polished? The applicable levels shall be as speci? The marking shall be sufficiently stable to withstand normal handling. Within the text, the SI units are shown in brackets, except that when AM is speci?
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
C For circles, the over thickness tolerances in this table apply to the diameter a4480 the circle corresponding to the width ranges shown. Width and length tolerances for abrasive cut plates over mm thick are not included in the table; consult producer.
For the purposes of this speci? Finish for Strip Interspersement of different melts is permissible if they are of approximately the same nominal thickness and are heat treated in the same operating period and under the same conditions time and temperature.
Inspection by the purchaser shall not interfere unnecessarily with the manufacturer. Hard 12 34 78?
Such a requirement for an element not listed in the product speci? However, unless the order speci? Note that Practices A requires the test to be performed on sensitized specimens in the low-carbon and stabilized types and on specimens representative of the asshipped condition for other types.
The results of this retest shall be within the speci? TR Finish—See Note 4. However, percentages must exhibit the same tendencies in all samples; that is, the several determinations of any individual element in a heat shall not vary both above and below the speci?
Bright Annealed Finish—See Note 4. Packaging, Marking, and Loading The material shall undergo mechanical tests such as tension test, hardness test, and bend test. Surface roughness measurements differ with different instruments, laboratories, and operators.
The material shall be accepted if the results of retests on retreated material are within the speci? B For circles, the over thickness tolerances in this table apply to the diameter of the circle corresponding to the width ranges shown. Thickness tolerances given in mm unless otherwise indicated. For S, see Note 6.
When intergranular corrosion is of concern, the purchaser should specify the corrosion test of This is a dull, nonre? An iron free abrasive wheel shall be used for such grinding and shall be operated at a speed ample to ensure that defective areas are cleanly cut out. NOTE 7—The term continuously, as applied to heat treatment, is meant to describe a heat-treating operation ast which one cut length follows another x480 the furnace.
When agreed by the seller and the purchaser, it is permitted to modify the cross section to 1? Approved April 1, For plates up to 10 in. It is permitted to round the edges to a 1? The manufacturer is permitted, if necessary, use a lower temperature resolution anneal or a stabilization anneal after a high temperature solution anneal in order to meet corrosion test requirements. a840
C Not including hard tempers of 2xx and 3xx series, dead-soft sheets, and deep-drawing sheets. NOTE 1—Thickness measurements are taken at least 10 mm in from the edge of the product, except that on widths less than 26 mm, the tolerances are applicable for measurements at all locations. This specification covers general requirements for flat-rolled stainless and heat-resisting steel plate, sheet, and strip. If the hardness difference between the two ends of the coil exceeds 5 HRB, or equivalent, or if the material is temper rolled, tensile properties must be determined on both coil ends.
Quenched in water or rapidly cooled by other means at a rate sufficient to prevent reprecipitation of carbides, as demonstrable by the capability of passing the test for resistance to intergranular corrosion speci?
