Product Code:SAE AMS5042
Title:Steel, Sheet and Strip, 0.15 Carbon, Maximum Forming Grade (NONCURRENT Aug 2009)
Issuing Committee:Ams E Carbon And Low Alloy Steels Committee
Scope:This specification has been declared “NONCURRENT” by the Aerospace Materials Division, SAE, as of August 2009. 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. “NONCURRENT” specifications are available from SAE upon request.
