Welding of 1Cr5Mo and 12Cr2Mo1R

I saw that E310-15 is used for 47015, but it seems a bit odd; why is a stainless steel welding material chosen for welding these two heat-resistant steels?
With this choice, it’s no problem. . Of course, the metal temperature is designed to be below 400°C in order to suppress the diffusion of C toward the weld metal boundary under high-temperature conditions, thereby preventing a reduction in high-temperature durability. . Above 400°C, nickel-based welding materials should be chosen. .
