Nakamura Stainless, a top stainless steel manufacturer and supplier in Pulau Ujong, Singapore, offers AWS Class E330-16 Electrodes for welding heat-resistant alloys. These electrodes are designed for high-temperature applications where resistance to oxidation and scaling is important. With stable arcs, minimal spatter, and excellent weld bead appearance, they are trusted for fabricating equipment that endures extreme heat. Nakamura Stainless maintains strict quality standards for every product, delivering reliable welding consumables for demanding industries. Their focus on innovation and accuracy makes E330-16 Electrodes a solid choice for power generation, petrochemical, and furnace equipment applications.
AWS Class E330-16 Electrodes contain 14-16% chromium, 34-37% nickel, and 1-2% silicon, with iron as the balance. The high nickel content ensures resistance to thermal shock and carburization, while chromium provides oxidation resistance. They offer a tensile strength of around 550 MPa and elongation of 30-35%. Weld deposits maintain their stability and strength even when exposed to temperatures over 1000°C. These features make them ideal for welding heat-resistant alloys, ensuring a long service life in high-stress and high-temperature conditions.
