What do the grades 1.25Cr-0.5Mo-Si and 2.25Cr-1Mo-0.25V mean, how were they determined, and are they based on Chinese standards or American standards?

1.25Cr-0.5Mo-Si, ASTM 182 F11 alloy steel

The percentage content of each alloy in the alloy steel

Which standard specifies the notation 1.25Cr-0.5Mo-Si? I haven’t found it either; please ask an expert to help. ASTM 182 does not use this notation either – it’s simply equivalent to F11

Isn’t this notation the standard notation?

This is a term used abroad for the 14Cr1Mo and 12Cr2Mo1V materials
