Chanchai Stainless in Bangkok provides AWS Class ER330 MIG and TIG filler wires and rods. These are engineered for welding high-nickel and heat-resistant stainless steels like Alloy 330. The fillers are designed for severe high-temperature environments and offer excellent oxidation and carburization resistance. With stable arc performance and minimal porosity, ER330 filler metals are the preferred choice for demanding thermal applications requiring long-term strength and metallurgical stability.
ER330 contains approximately 34 to 37% nickel and 14 to 17% chromium, with low carbon content. The weld deposit provides excellent creep strength and oxidation resistance at temperatures up to 1150°C. It exhibits tensile strength in the range of 600 to 700 MPa and maintains good ductility and toughness under thermal stress. The alloy remains austenitic after welding, preserving strength over time.
