A vs SA for boiler tube

[kclim]

Are the SA and A grades for boiler tube interchangeable? In particular, was looking at A/SA-213 and 209.

thread292-209678 seems to suggest for pressure vessels, there is information in ASME II A which details equivalent SA/A grades. Does this apply to boiler tube as well?

Thanks
