The E312‑16 electrode is specifically designed for shielded-metal-arc welding (SMAW) of both cast and wrought stainless steels, as well as for joining dissimilar combinations of stainless and carbon/low alloy steels. The typical composition of the deposited weld metal includes about 28.0–32.0% chromium, 8.0–10.5% nickel, up to 0.75% molybdenum, 0.5–2.5% manganese, ≤ 1.0% silicon, and carbon ≤ 0.15%. ([Weld Wire][1]) In terms of mechanical properties (as-welded), you can expect a tensile strength of around 95–110 ksi (approximately 660-760 MPa) and an elongation of about 22-30%. ([Midalloy][2]) This electrode is versatile enough for use in all positions (except sometimes vertical down) and can be used with either AC or DC+ polarity, depending on the brand. ([tokoc.com][3])
