high quality AWS E312-16 3.2mm stainless steel welding rod electrode
AWS A5.4 E312-16
Description:
AWS E312-16 welding electrode is a kind of Lime titania type cover used for welding high carbon steels, tool steels, dissimilar steels and Cr29Ni9 cast steels, duplex stainless steels as well as problem steels.
Instruction:
1. The electrodes should be baked under 200-250º C for an hour before welding.
2. Direct current had better be used and the current should not be too strong.
