ASTM B462-04 pdf free.Standard Specification for Forged or Rolled UNS N06030,UNS N06022,UNS N06035,UNS N06200, UNS N06059,UNS N06686,UNS N08020, UNSN08024, UNS N08026, UNS N08367,UNS N10276, UNS N10665,UNS N10675,UNS N10629,UNS N08031,UNS N06045, UNS N06025, and UNS R20033 Alloy Pipe Flanges,Forged Fittings, and Valves and Parts for Corrosive High-Temperature Service.
Alloy N08367 shall be furnished in the solutionannealed condition.The recommended heat treatment shall consist ofheating to a minimum temperature of 2025°F (1105°C) andquenching in water, or rapidly cooling, by other means.Heat treatment may be performed before machining.6.Chemical Composition:The material shall conform to the requirements as tochemical composition prescribed in Table 1.If a product (check) analysis is performed by thepurchaser,the material shall conform to the requirementsspecified in Table 1 subject to the permissible tolerances inSpecification B 880.Mechanical Properties and Other Requirements:The material shall conform tothe requirements as to mechanical properties prescribed inTable 2 at room temperature.After machining,valve bodies, fit-tings, and other pressure-containing parts shall be tested to thehydrostatic shell-test pressures prescribed in ANSI B16.5 forthe applicable alloy steel rating for which the forging isdesigned and shall show no leaks. Forgings ordered underthese specifications for working pressures other than thoselisted in the American National Standard ratings shall be testedto such pressures as may be agreed upon between the manu-facturer and the purchaser. No hydrostatic test is required for welding neck orother flanges.The forging manufacturer is not required to performpressure tests on rough forgings that are to be finally machinedby others. The fabricator of finished forged parts is not requiredto pressure-test forgings that are designed to be pressurecontaining only after assembly by welding into a larger structure. However,the manufacturer of such forgings isresponsible as required in accordance with 15.1 for thesatisfactory performance of the forgings under the final testrequired in 7.2.
For the purpose of tests, the necessary extra forgings ortest bars shall be provided.The test specimen, if cut from aflange,shall be cut tangentially from the flange portionapproximately midway between the inner and outer surfacesand approximately midway between the front and back faces.When it is impractical to provide forgings for test purposes, testbars may be made from the billet or bar,provided they aregiven approximately the same reduction and heat treatment asthe forgings.ASTM B462 pdf download.
