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.
