Hello Srinivas,
Attached are the compositions and the mechanical properties of all grades of ASTM A514.The back to back grades adopted for boiler and pressure vessels are classified under SA -517. You may see the comparative descriptions for all the grades concerned.
Since these steels not used for common fabrication work, one has to compare all the properties then only look for substitution. You may not get the exact equivalence and replacement , if so is intended.
If you have any specific issue with this steel feel free to drop a lone.
Thanks.

Subject: Re: [MW:10951] ASTM 514 equivalent grade material?
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

Dear all.
pl let me know..
wat r equivalent grade material for ASTM 514?
& where we can refer for that?
Is it only chemical composition only..
or any specs tells about this?
Regards
Srinivas
