Hi,
Both EN 1.4306 (X2CrNi19-11) and EN 1.4307 (X2CrNi18-9) are commonly cross-referenced to ASME/ASTM Type 304L, UNS S30403. Grade equivalence alone does not establish ASME Code compliance: the applicable specification depends on the product form. For example, plate, sheet, or strip may use SA-240 Type 304L, while pipe may use SA-312 TP304L. Verify the material against the specification and Code edition required for the application.


Thanking you,

With best regards,
