7、d use of the item should 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

8、 and billets of the 400 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-roll

9、ed or as-forged condition. 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
