Emilio Stainless, a reputable manufacturer and supplier located in Manila, Philippines, offers top-notch AWS Class ER312 MIG and TIG filler welding wires and rods. These ER312 filler materials are celebrated for their strength, crack resistance, and versatility, making them perfect for joining dissimilar steels and challenging stainless alloys. At Emilio Stainless, we prioritize quality, ensuring that our products consistently meet the high standards required by various industries. With outstanding arc stability and weld integrity, we proudly support fabricators and welders across the Philippines with premium stainless steel filler metals.
The AWS Class ER312 filler wire and rod are made from a high-alloy austenitic stainless steel, featuring around 29-32% chromium and 8-10% nickel. This unique composition grants exceptional crack resistance, impressive tensile strength (typically around 100,000 psi), and excellent weldability, even on high-carbon or hardenable steels. Whether you’re using MIG (GMAW) or TIG (GTAW) welding processes, ER312 performs reliably in tough conditions, providing stable arc characteristics, a smooth bead appearance, and solid resistance to heat and corrosion.
