Adam Stainless, located in Canberra, Australia, has built a solid reputation as a reliable manufacturer and supplier of top-notch welding consumables, including the AWS Class ER420 MIG and TIG filler wires. These products are celebrated for their dependable performance and long-lasting durability, meeting the rigorous standards of the industry. The ER420 filler wire is specifically crafted for welding martensitic stainless steels, offering impressive strength, wear resistance, and a decent level of corrosion resistance, making it perfect for tough applications across various sectors in Australia.
Typically, the AWS Class ER420 filler wire contains around 12-14% chromium and has a low nickel content, which allows it to achieve tensile strengths of up to 90 ksi. This unique composition provides excellent hardness and toughness, making it ideal for welding martensitic stainless steels that are often exposed to abrasion and moderate corrosion. The wire is known for its stable arc characteristics, resulting in welds that boast high mechanical strength and resistance to tempering.
