Walid Stainless, located in Tunis, Tunisia, is a reputable manufacturer and supplier of high-quality stainless steel products and welding consumables. They offer AWS Class ER420 MIG and TIG filler welding wire and rod, specifically crafted for top-notch welding of martensitic stainless steels. With a strong emphasis on quality control and technical support, Walid Stainless guarantees that these filler materials deliver outstanding arc stability, smooth weld deposits, and excellent mechanical properties. The ER420 wire and rod are versatile enough for both manual and automated welding processes, ensuring dependable and consistent results for industrial and repair tasks.
Typically, AWS Class ER420 filler materials consist of 12–14% chromium, 0.15% carbon, along with trace amounts of manganese and silicon, which contribute to their high strength, good toughness, and moderate corrosion resistance. They yield weld deposits with a tensile strength of about 580–620 MPa, providing remarkable wear resistance and durability. These materials create smooth, uniform welds with minimal spatter, making them particularly suitable for applications that require heat treatment post-welding.
