Weston Stainless, Midland, UK, is a top distributor of high-quality stainless steel welding consumables such as AWS Class ER330 MIG and TIG Filler Welding Rod and Wire. Produced from Grade ER330 stainless steel, this filler possesses excellent oxidation resistance, high-temperature strength, and good weldability. It is available in both rod and wire form and is suitable for welding 330 stainless steel parts to provide resistance in extreme heat and corrosive settings. ER330 welding rod and wire are used extensively in petrochemical, furnace, and heat treatment industries.
AWS Class ER330 MIG and TIG Filler Welding Wire and Rod consists mainly of 34-37% nickel and 17-20% chromium, with small percentages of manganese and silicon, offering superior oxidation resistance. It possesses a tensile strength of approximately 550 MPa and yield strength of 260 MPa, an elongation of about 40%. It has a physical property of 8.0 g/cm³ density and superior thermal expansion resistance. This alloy maintains its excellent strength and corrosion resistance at temperatures up to 1150°C, which makes it suitable for high-temperature welding operations.
