Differences and application ranges of R307 and R307C electrodes

I would like to ask the experts: For 15CrMo welding, R307 is used, but R307C is also employed; it is said that the version with C added is a hydrogen-resistant welding electrode. Is this the reason for the difference? Thank you

It’s just a matter of different grades; grade C has stricter requirements regarding ingredients
