From I did in past, it is allowed to substitute material when the following requirement/number of factors are met to the original mat'l (I notice this depends on Client Spec).
1. Carbon content
2. Sulfur composition
3. Phosphor composition
4. Mechanical properties i.e. yield strength, tensile strength, elongation and etc
5. Carbon equivalent (shall not exceed CEQ maximum) or PCM max
6. Impact test (if required by Client)
Have a nice day
