Lecong Stainless Manufacturer and Suppliers in Da Nang, Vietnam, provides AWS Class ER330 MIG and TIG filler wire and rod designed for welding heat-resistant alloys. With great oxidation resistance and stability at high temperatures, ER330 is used for welding 330-grade stainless steels. Its stable arc characteristics, smooth bead finish, and consistent feedability make it ideal for critical high-temperature fabrication. Lecong Stainless supplies ER330 filler wire and rod to industries across Vietnam and internationally, ensuring top-notch welds in environments where thermal stability, scale resistance, and durability under high temperatures are crucial.
ER330 typically contains 33–37% nickel, 14–17% chromium, and ≤0.08% carbon. This composition provides excellent oxidation and carburization resistance at high temperatures. Mechanical properties include tensile strength ranging from 75,000–80,000 psi, yield strength between 40,000–45,000 psi, and elongation of 30–35%. The weld deposit maintains toughness and scale resistance up to 1000°C (1832°F). With reliable arc performance and resistance to thermal fatigue, ER330 ensures dependable welds in applications where heat and oxidation resistance matter.
