You can recertify ASTM material to ASME SA material as a manufacturer per UG-10, making sure that it conforms to that SA material

Yes, You can use ASTM materials qualified PQR for ASME materials
welding.
No restrictions as per ASME sec VIII Div-1 (Refer QW-28) or ASME Sec-
IX(Refer QW-420).
"If an unlisted base metal has the same UNS number designation as a
base metal listed in table QW/QB-422,
it shall be considered as assigned to that P-Number or P-Number plus
Group Number. However, only base metals listed in table QW/QB-422 with
minimum tensile strength values may be used for procedure
qualification test coupons".
Cheers!
