SAE AMS5330D

This specification has been declared “NONCURRENT” by the Aerospace Materials Division, SAE, as of February 1998. It is recommended, therefore, that this specification not be specified for new designs. “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.

This specification covers a low-alloy steel in the form of investment castings. Primarily for parts of intricate design requiring tensile strengths up to 200,000 psi (1380 MPa) after hardening and tempering heat treatment.
