自2008年12月起，SAE航空航天材料部已宣布本规范“取消”。通过这一行动，本文件将保留在航空航天标准索引的数字部分，并注明已被“取消”。以下规范涵盖了类似但不一定完全相同的产品。然而，本清单仅供参考，不构成用这些规范代替已取消规范的权力。ASTM A29/A29M热锻碳素钢和合金钢棒ASTM A519无缝碳素钢和合金钢机械管ASTM A668/A668M一般工业用碳素钢和合金钢锻件ASTM A711/A711M钢锻件本规范涵盖以棒材、锻件、机械管和锻坯形式存在的含铅碳钢。 这些产品通常用于加工量或复杂性要求使用易切削钢以获得良好表面光洁度的零件，但使用不限于此类应用。

This specification has been declared "CANCELLED" by the Aerospace Materials Division, SAE, as of December 2008. By this action, this document will remain listed in the Numerical Section of the Aerospace Standards Index noting that has been "CANCELLED".Similar but not necessarily identical products are covered in the following specifications. However, this listing is provided for information only and does not constitute authority to substitute these specifications for the CANCELLED specification. ASTM A29 / A29M Steel Bars, Carbon and Alloy, Hot-Wrought, General Requirements forASTM A519 Seamless Carbon and Alloy Steel Mechanical TubingASTM A668 / A668M Steel Forgings, Carbon and Alloy, for General Industrial UseASTM A711 / A711M Steel Forging StockThis specification covers a leaded carbon steel in the form of bars, forgings, mechanical tubing, and forging stock.These products have been used typically for parts on which the amount or complexity of machining warrants use of a free-cutting steel to yield good surface finish, but usage is not limited to such applications.
