Adam Stainless, located in Canberra, Australia, stands out as a top manufacturer and supplier of premium welding consumables, including the AWS Class ER347 MIG and TIG filler wires. Known for their reliable performance and strict adherence to industry standards, Adam Stainless offers welding products that are crafted to create strong, corrosion-resistant welds. The ER347 filler wire is specifically designed for applications that demand exceptional resistance to intergranular corrosion, making it a trusted option for stainless steel welding in various Australian industries.
The AWS Class ER347 filler wire is made up of roughly 18-20% chromium and 9-13% nickel, with niobium (columbium) added to prevent carbide precipitation and intergranular corrosion. It boasts tensile strengths of about 75 ksi, along with good ductility and toughness. This unique composition guarantees durable welds that can withstand cracking and corrosion, particularly in high-temperature and corrosive settings.
