Emilio Stainless is a top-notch manufacturer and supplier located in Manila, Philippines, specializing in a diverse array of high-quality stainless steel welding consumables. Among their offerings are the AWS Class ER420 MIG and TIG Filler Welding Wire and Rod. Renowned for their reliability and performance, Emilio Stainless guarantees that every filler wire adheres to international quality standards, ensuring consistency and strength. The ER420 welding consumables are crafted for applications that require outstanding wear and corrosion resistance, making them a go-to choice for professionals in fabrication, tool manufacturing, and repair across various industries.
The AWS Class ER420 MIG and TIG Filler Welding Wire and Rod are made from martensitic stainless steel alloys, featuring about 12–14% chromium, 0.3% carbon, 0.4–1% manganese, 0.3–0.6% silicon, and trace amounts of nickel. This unique blend provides exceptional hardness, strength, and moderate corrosion resistance. The weld metal produced boasts a tensile strength of approximately 700–800 MPa and maintains good toughness after appropriate heat treatment. The combination of high carbon and chromium enhances wear resistance, while post-weld tempering minimizes brittleness, ensuring stable mechanical performance even in demanding situations.
