These are SAW process solid electrode designations in accordance with SFA 5.17. More specifically, these are high manganese electrode formulations. You should obtain a copy of SFA 5.17 read it to understand electrode chemical composition ranges and associated mechanical properties.

i am not familiar with em10K

em12k is a basic carbon steel sub-arc wire for non-stress relieved procedures. We stress relieved it for years but now it is not certified (lincoln 860) for PWHT

em14k is a basic carbon steel sub-arc wire for stress relieved procedures (at our shop) & used when impact test are required (at our shop) & used in our arc-wave machines.

this is a simplified explanation.

it's basically a difference in chemistries for required results.
