Nakamura Stainless stands out as a top manufacturer and supplier in Pulau Ujong, Singapore, renowned for providing high-quality stainless steel welding consumables that cater to a variety of industrial needs. The AWS Class ER312 MIG and TIG Filler Welding Wire and Rod is specifically designed for joining different metals and high-alloy steels. Thanks to its high ferrite content and well-balanced chemistry, it boasts impressive crack resistance and exceptional strength. These filler wires and rods ensure excellent weld quality, even on challenging materials, guaranteeing durability and reliability. They are extensively used in critical applications where versatility, toughness, and corrosion resistance are vital for long-lasting performance.
The AWS Class ER312 MIG and TIG Filler Welding Wire and Rod features a composition of about 29–32% chromium and 8–10% nickel, along with manganese, silicon, and carefully controlled carbon levels. This high-alloy makeup offers remarkable resistance to cracking, along with excellent strength and toughness, even in high-stress situations. The weld deposits show a tensile strength of around 850 MPa while maintaining good ductility. The elevated ferrite content boosts resistance to solidification cracking, making it perfect for welding dissimilar steels, high-alloy steels, and tricky base metals. These characteristics ensure secure, durable, and defect-free welds in demanding environments.
