AWS Class ER630 MIG and TIG filler wires and rods are crafted from a high-alloy austenitic stainless steel, featuring around 25–26% chromium, 9–10% nickel, 3–4% molybdenum, and a low carbon content. This unique blend offers remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in environments with chlorides. On the mechanical side, ER630 weld deposits provide high tensile strength, excellent toughness, and outstanding durability even at elevated temperatures. These filler metals ensure smooth arc performance, a consistent bead appearance, and reliable fusion with base metals, resulting in long-lasting, high-integrity welds.
