This specification has been declared “NONCURRENT” by the Aerospace Materials Division, SAE, as of March, 2008. It is recommended, therefore, that this specification not be specified for new designs. “NONCURRENT” refers to those specifications which have previously been widely used and which may be required for production or processing of existing designs in the future. The Aerospace Materials Division, however, does not recommend these specifications for future use in new designs. Similar but not necessarily identical products/processes 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 “NONCURRENT” specification.

ASTM A 576 Grade 1015; ASTM A 108 Grade 1015; ASTM A 519 Grade 1015

This specification covers a low-carbon steel in the form of bars, forgings, mechanical tubing, and forging stock.

These products have been used typically for steel-backed bearings and carburized parts requiring a low maximum hardness of uncarburized surfaces after quenching the steel in water from a temperature above the transformation range of the steel, but usage is not limited to such applications.
