Treatment of Sheet Metal Parts Corrosion-Resistant Steel(NONCURRENT Jun 1993)
This specification covers the engineering requirements for a treatment to provide enhanced corrosion resistance to sheet metal parts, such as brackets, spacers, and washers, fabricated from martensitic Corrosion-resistant steels, usually AMS 5504 or AMS 5508 and having hardness not higher than 40 HRC, or ferritic corrosion-resistant steels, usually AMS 5506. The treatment is not recommended for use on parts subject to impact in service.
AMS2550E has been reaffirmed to comply with the SAE five year review policy.
This specification has been declared "NONCURRENT" by the Aerospace Materials Division, SAE, as of June 18, 1993. It is recommended, therefore, that this specification not be specified for new designs.
This cover sheet should be attached to the "D" revision of the subject specification.
"NONCURRENT" refers to those materials which have previously been widely used and which may be required on some existing designs in the future. The Aerospace Materials Division, however, does not recommend these as standard materials for future use in new designs. Each of these "NONCURRENT" specifications is available from SAE upon request.
