Nakamura Stainless, a trusted supplier in Pulau Ujong, Singapore, offers AWS Class ER330 MIG and TIG Filler Wires and Rods designed for welding heat-resistant stainless steels. They resist oxidation and carburization, making them ideal for high-temperature applications. Known for stable arc characteristics and consistent weld bead quality, ER330 consumables ensure strong welds even under thermal cycling. Nakamura Stainless guarantees compliance with worldwide quality standards, providing welding products suitable for industries like petrochemical, furnace manufacturing, and power generation, where heat resistance and reliability are vital.
AWS Class ER330 wires and rods contain 14–16% chromium and 34–37% nickel, with small amounts of silicon and manganese, balanced by iron. This high-nickel makeup offers excellent resistance to oxidation and carburization at high temperatures. Weld deposits typically show tensile strength of around 550 MPa and elongation of 30–35%, ensuring toughness and ductility when exposed to heat. They also maintain mechanical stability during thermal cycling, making them reliable for high-temperature components. These features guarantee durability and weld integrity for long-term use in industrial applications.
