| An improved version of ER3 0 9L with the addition of silicon (Si) to its composition. Designed for welding dissimilar metals, particularly for joining austenitic stainless steels to carbon and low-alloy steels The addition of silicon (Si) in ER3 0 9LSI improves the weld metals fluidity and wetting characteristics, resulting in better bead appearance and increased penetration. Provides excellent corrosion resistance, making it ideal for applications in corrosive environments. The welds retain their corrosion-resistant properties, ensuring the integrity of the welded structure. It is versatile and suitable for a wide range of applications that involve welding austenitic stainless steels. The improved wetting of ER3 0 9Lsi makes it suitable for high speed welding. ER3 0 9LSI is commonly used in industries such as petrochemical, food processing, power generation, and other applications that involve high-temperature and corrosion-resistant welds. It is particularly valuable for joining stainless steel to carbon steel or for overlaying stainless steel surfaces with a corrosion-resistant layer.
