316Si / 316LSi

316L / 316LSi welding consumables are designed to produce smooth, strong, and corrosion-resistant welds on 316 and 316L stainless steel. These products are widely used in pipe, plate, and structural fabrication, where clean bead appearance and long service life are important. The higher silicon content improves weld pool flow and toe blending, especially in fillet welds. This makes 316LSi welding wire a preferred choice for applications that demand both strength and visual consistency in stainless steel joints.

Key Features and Benefits of Superon 316L / 316LSi

316L and 316LSi products are developed to meet the requirements of stainless steel welding in demanding industrial environments.

Key features and benefits include:

• Excellent Weld Bead Appearance  The higher silicon content improves molten metal fluidity, allowing the weld pool to spread evenly and settle smoothly. This results in uniform weld beads with clean toe blending, reducing undercut risk and minimising post-weld finishing and grinding work.
• Ideal For 316 And 316L Stainless Steels The consumable is specifically formulated to match the metallurgical composition of 316 and 316L stainless steels, ensuring sound fusion, compatible mechanical properties, and reliable corrosion performance in both fabrication and surfacing applications.
• Strong Corrosion Resistance The deposited weld metal offers excellent resistance to moisture, industrial chemicals, and corrosive environments, making it suitable for process plants, marine-influenced areas, and chemical handling equipment.
• Low Carbon Content  The controlled low carbon level reduces the risk of intergranular corrosion, especially in high-temperature or chemically aggressive service conditions. This helps maintain weld joint integrity over long service life.
• Good Mechanical Strength The weld metal delivers reliable tensile strength and ductility, enabling it to withstand mechanical loading, vibration, and service stresses commonly encountered in industrial installations.
• Stable Welding Performance The consumable provides smooth and stable arc behaviour with minimal spatter, supporting better welder control, improved productivity, and consistent weld quality.
