Aditya Stainless, a leading manufacturer and supplier based in Kolkata, India, specializes in high-performance AWS Class ER330 MIG and TIG Filler Welding Wire and Rod. These products are perfect for welding heat- and oxidation-resistant alloys. ER330 is designed specifically for working with both wrought and cast forms of Alloy 330, which is renowned for its impressive strength and resistance to oxidation at temperatures reaching up to 1150°C (2100°F). This filler metal excels in high-temperature settings where thermal cycling and carburizing are prevalent. It’s commonly used in furnace components, heat treating fixtures, and petrochemical processing, ensuring durable, crack-resistant welds even in the most extreme conditions.
ER330 is composed of about 35–37% nickel, 17–20% chromium, 1–2% manganese, and a low carbon content (≤ 0.08%). This unique blend provides exceptional resistance to oxidation, carburization, and scaling at elevated temperatures. It boasts a tensile strength of at least 80,000 psi (550 MPa), a yield strength of at least 40,000 psi (275 MPa), and an elongation of around 30%. Even after prolonged exposure to high heat, ER330 maintains its mechanical integrity. Its stable austenitic structure helps prevent embrittlement and ensures excellent weldability with minimal cracking. Suitable for both MIG and TIG processes, it guarantees clean, high-quality welds in demanding heat service conditions.
