High-end welding scenarios such as low-temperature pressure vessels and engineering steel structures require strict weld purity and low-temperature toughness. Our high-purity 45# atomized silicon powder adopts multi-purification technology with stable 43%-47% silicon content and strictly controlled trace impurities. It refines weld grains and greatly improves low-temperature impact toughness and crack resistance, avoiding weld cracking in low-temperature working conditions. Compliant with high-end industrial welding material standards, it is ideal for low-temperature steel electrodes and pressure vessel welding production with qualified non-porous and impurity-free welds.
