Ordering Information3.1 It is the responsibility of the purchaser to specify all requirements that are necessary for material ordered under thisspecification. Such requireme
5、nts may include but are not limited to the following:3.1.1 Quantity (weight or number of pieces),3.1.2 Name of material: type or UNS designation (Table 1),3.1.3 Condition,3.1.4 Cross section (round, round-cornered square, etc.),3.1.5 Form: bar or forging billet,3.1.6 Applicable dimensions, including
6、 size, thickness, width, and length,3.1.7 ASTM designation and date of issue,3.1.8 Preparation for delivery (see Specification A484/A484M),3.1.9 Marking (see Specification A484/A484M), and3.1.10 Exceptions to the specification or special requirements.3.2 If possible, the intended use of the item sho
7、uld be given on the purchase order especially when the item is ordered for aspecific end use or uses.NOTE 1A typical ordering description is as follows: 10 000 lb, Type 420, annealed, round-cornered square billets, ASTM A314 dated forvalve parts.4. Manufacture4.1 AnnealingBlooms and billets of the 4
8、00 series of stainless steel types which are highly hardenable, such as Types 414,420, 431, 440A, 440B, and 440C, are commonly annealed prior to shipment and so specified in order to avoid the possibility ofthermal cracking. Those grades are not normally furnished in the as-rolled or as-forged condi
9、tion. Other hardenable grades, suchas Types 403, 410, 416, and 416 Se, which may also require annealing, depending on their composition and size, are furnishedsuitable for cold cutting when so specified on the purchase order.1 This specification is under the jurisdiction ofASTM Committee A01 on Stee
