In an electrode label, what does B3 denote?

Explanation:
The code on an electrode label encodes what elements are in the weld metal. The B3 marking specifically indicates chromium is present in the electrode’s alloy. Chromium is added to give corrosion resistance and high‑temperature strength, which is why this electrode is associated with chromium-containing (such as stainless or chromium-bearing) steels. This mark doesn’t describe polarity (DC/AC), hydrogen content, or a titanium base—that information would be indicated elsewhere in the label.
