Preheating is a must for these materials, because of carbon content (nearl %0,40) 300 C preheating is necessary and low cooling rate. After welding it's better to use pwht (normalizing)
ER80S-B2 - (CrMo1), E8018-B2 (CrMo1) can be used or some of dissimilar consumables, such as ER307 (18 8 Mn), ER312 (29 9)
Best regards.
