Applications of Stainless Steel 307Si Filler Wires
What is Stainless Steel 307Si Filler Wires?
Stainless steel 307Si filler wires are solid, corrosion-resistant rods that combine two pieces of stainless steel. This alloy is ideal for joining components made from types 304 and 304L stainless steels and other common austenitic grades. Depending on the specific project requirements, these filler wires are also available in various diameters and lengths.
Stainless steel 307Si filler wires are an all-position electrode made from stainless steel alloy containing 18% chromium and 10% nickel. It is highly corrosion-resistant and perfect for welds that require excellent crack resistance and strength at elevated temperatures up to 600 degrees Celsius.
Benefits of Stainless Steel 307Si Filler Wires
The primary benefit of using stainless steel 307Si filler wires is its high corrosion resistance – especially compared to other steel alloys – due to its high chromium content (18-20%) and low carbon content (0.08%). Additionally, these rods have excellent flexibility that allows them to maintain their shape even after being subjected to extreme temperatures or pressure during welding. Finally, these rods are extremely easy to work with because they require minimal preparation before use and can be applied quickly in most cases.
Applications of Stainless Steel 307Si Filler Wires
Stainless steel 307Si filler wires are commonly used in welding AISI grades 304L, 308L and 347 stainless steel. These electrodes produce smooth, uniform arcs with very low spatter levels on AC or DC power sources. They have good wetting action, which ensures the complete fusion of the parent metal into the weld bead and superior puddle control for easy slag removal when working in vertical positions. Additionally, these electrodes offer good resistance to intergranular corrosion caused by carbide precipitation during welding operations.
The versatility of these electrodes makes them ideal for use in fabrication industries such as food processing equipment manufacturers, chemical plants, paper mills, pharmaceutical plants and other related industries requiring superior corrosion resistance welds in high-temperature environments. These electrodes can also be used for joining dissimilar metals, including carbon steels, to austenitic stainless steels such as 304L/308L or 321/347 combinations where extra corrosion protection is required.
