Discontinued ASTMs
Discontinued ASTMs
(OP)
Is there any general path to follow in specifying material when an ASTM has been cancelled without substitution? Some manufacturers continue making material to a cancelled spec, like for example, ASTM A569. Even though the material is available, I am reluctant to specify its use since ASTM A569 has been discontinued. But since no substitution was provided by the cancellation notice I am not sure what to specifiy for commercial quality hot rolled steel sheet. I don't want to specify something that will be hard to obtain for a non-critical application.
I would appreciate any thoughts, in general, on use of cancelled ASTM specs and more specifically, substitutions for ASTM A569.

RE: Discontinued ASTMs
For what it's worth, in aircraft application we follow a manual check and comparision of other specs (SAE, MIL-specs, ASTM, etc.) and substantiate alternate materials based on equivalent alloy composition, succeptability to corrosion, mechanical properties (tensile, compressive, shear strength, etc.), availability, and special applications (elevated temperature, etc). This can be a long and exhaustive process, but the internet helps to speed our search.
I hope you find a quick answer to your obsolete spec.

The handbook is available in public libraries. It is also useful for finding foreign standard specs, eg DIN, British, French and Japanese Standards.
