Peened castings shall be marked with Maltese cross approximately 1?
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. For the products described, mechanical property limits for the respective size ranges are based on the analyses of asgm least data from standard production material with no more than ten data from a given lot.
This abstract is a brief summary of the referenced standard. Width of reduced section, 1? When single units are shown, these indicate the maximum amounts permitted. T6 Solution heat-treated and then arti? Separately n108 test specimens astj be cast in iron molds.
Number of Tests B Analysis shall be made for the elements for which limits are shown in this table. G Composite rating based on ease of cutting, chip characteristics, quality of? This specification covers aluminum-alloy permanent mold castings.
N Bb108 to suitability of alloy to withstanding brazing temperatures without excessive distortion or melting. H Composite rating based on ease and speed of polishing and quality of? Should any analysis by the producer or the purchaser establish that an Others element exceeds the limit of Each or that the aggregate of several Others elements exceeds the limit of Totalthe material shall be considered nonconforming.
With qstm ends, 23? The purchaser shall have the right to perform any of the inspections and tests set forth in the speci? D Yield strength to be evaluated only when speci? All tests and inspection shall be so conducted as not to interfere unnecessarily with the operation of the works. Peening may be accomplished either hot or cold and shall be performed by methods which are acceptable to the purchaser.
Rejection and Rehearing The weight of a prepared sample shall not be less than 75 g. If the castings are to be heat treated and separately cast specimens are to be used, the specimens representing such castings shall be heat treated with the castings they represent. Rejection should be reported to the producer promptly and in writing.
A designation ast, in con? A n108 in parentheses indicates the year of last reapproval. Ability of alloy to withstand stresses from contraction while cooling through hot-short or brittle temperature range. Last previous edition B — This standard has been approved for use by agencies of the Department of Defense. Historical Version s – view previous versions of standard.
If the producer has determined the chemical composition of the material during the course of manufacture, he shall not be required to sample and analyze the? Combining values from the two b10 may result in non-conformance with the standard.
Pure materials, recycled materials, and master alloys may be used to make alloys conforming to this specification. For purposes of determining conformance to these limits, an observed value or a calculated value obtained from analysis shall be rounded b018 the nearest unit in the last right-hand place of?
B For purposes of determining conformance with this speci?
One per melt-heat combination shall be tested when tensile properties of castings are to be determined.
If castings are to be heat treated and tests are to be obtained on the castings, the test specimens shall be taken from the castings after heat treatment. Current edition approved May 10, Overall length, 4 in.
T1 Cooled from an elevated temperature shaping process and naturally aged to a substantially stable condition. Packaging methods and containers shall be so selected as to permit maximum utility of mechanical equipment in unloading and subsequent handling.
