The **AWS Class ERNiCrMo-4 MIG and TIG Filler** wire is a nickel-chromium-molybdenum alloy that consists of about 60% Nickel, 20–22% Chromium, 8–10% Molybdenum, along with trace amounts of Iron, Tungsten, and Cobalt. This unique blend offers remarkable resistance to strong oxidizing and reducing acids, like hydrochloric and sulfuric acids, while ensuring high mechanical strength. It boasts a tensile strength of roughly 760 MPa, yield strength of 550 MPa, and an elongation of 30–35%. The filler wire guarantees smooth arc stability, minimal spatter, and excellent metallurgical integrity, resulting in robust, corrosion-resistant weld deposits.
