3、 N08354, and UNSR20033 plate, sheet, and strip in the annealed temper.1.2 ASTM International has adopted definitions wherebysome grades, such as UNS N08904, previously in this speci-fication were recognized as stainless steels, because thosegrades have iron as the largest element by mass percent. Su
4、chgrades are under the oversight of ASTM Committee A01 andits subcommittees. The products of N08904 previously coveredin this specification are now covered by Specifications A 240/A 240M and A 480/A 480M.1.3 The values stated in inch-pound units are to be regardedas standard. The values given in par
