Hi,
What is your impact requirement. Both electrodes will have same impact strength. In case stick electrodes if you want better impact properties less than -196C then you should go for E316-15 electrodes as it is lime coated where as 316-16 is rutile,lime coated so its impact properties will be less than E316 -15.
