The right filler wire choice is essential for obtaining optimal results and CS to SS Welding Filler Wire is very important when welding dissimilar weld between CS material and SS Material.
CS to SS welding filler wire is a special type of welding filler wire that has specific characteristics and features that make it ideal for use in certain welding applications.
CS to SS welding filler wire combines the benefits of carbon steel and stainless steel in one product, offering superior weld strength, toughness and corrosion resistance.
CS to SS Welding Filler Wire
One key benefit of CS to SS welding filler wire is its ability to reduce cracking during welding. Stainless steel has a higher thermal expansion coefficient than Carbon steel, which means that it will expand and contract at different rates when exposed to heat.
This can lead to cracks forming in the weld area without appropriate precautions being taken. However, using filler wire with similar mechanical properties minimizes this risk by facilitating more even heating and cooling during the welding process.

Best CS to SS Welding Filler Wire
When it comes to welding, choosing the right filler wire can make a huge difference in the quality of your welds. One of the most popular types of welding is CS to SS welding, which involves joining carbon steel and stainless steel.
Most commonly used CS to SS Welding Filler Wires are:
- ER309L
- ER309LSi
- ERNiCrFe-3
- ERNiCrMo-3
ER309L
ER309L is a type of filler metal or welding wire used for welding similar alloys, including 300 series stainless steels, and dissimilar metals such as carbon and low-alloy steels. It is a low-carbon stainless steel TIG welding wire that contains 24-25% chromium and 12-14% nickel.
ER309L welding wire is designed to provide good weldability and a stable arc while also providing good corrosion resistance in the weld area. The low carbon content also helps to minimize the risk of carbide precipitation and intergranular corrosion.
This type of welding wire is commonly used in applications such as welding of furnace components, food processing equipment, chemical processing equipment, and other high-temperature and corrosive environments.
ER309LSi
ER309LSi is a type of welding wire that is similar to ER309L, but with the addition of silicon (Si) to its chemical composition. It is a low carbon stainless steel TIG welding wire that contains 23-25% chromium, 12-14% nickel, and 0.65-1.00% silicon.
The addition of silicon to ER309LSi welding wire helps to improve the weld pool fluidity and wetting action, which can lead to better weld penetration and reduced porosity. This makes it a good choice for welding thicker sections of stainless steel.
ER309LSi is also known for its good corrosion resistance in high-temperature applications and its ability to resist cracking and distortion during welding. It is commonly used in applications such as welding of stainless steel sheets, plates, pipes, and tubes, as well as in the fabrication of food processing equipment, chemical processing equipment, and other high-temperature and corrosive environments.
ERNiCr-3
ERNiCrFe-3 is a type of filler metal or welding wire used for welding nickel-chromium-iron alloys, such as Inconel 600, Incoloy 800 and 825. It is a nickel-based TIG welding wire that contains approximately 72% nickel, 15% chromium, 8% iron, and small amounts of other elements such as molybdenum, titanium, and aluminum.
ERNiCrFe-3 welding wire is designed to provide high strength and excellent resistance to corrosion, oxidation, and high-temperature environments. It is commonly used in applications such as aerospace, chemical processing, petrochemical, and power generation industries.
This type of welding wire provides excellent weldability and produces a clean and smooth weld bead. It is also suitable for welding dissimilar metals, including nickel alloys, stainless steels, and carbon steels.
ERNiCrMo-3
ERNiCrMo-3 is a type of welding wire or filler metal that is primarily used for welding nickel-chromium-molybdenum alloys, such as Hastelloy C-276 and Inconel 625. It is a nickel-based TIG welding wire that contains approximately 62.5% nickel, 22% chromium, 14% molybdenum, and small amounts of other elements such as iron, tungsten, and cobalt.
ERNiCrMo-3 welding wire is known for its excellent resistance to a wide range of corrosive environments, including oxidizing and reducing acids, alkalis, and saltwater. It is also highly resistant to stress corrosion cracking and pitting in high-temperature and high-pressure environments.
This type of welding wire is commonly used in applications such as chemical processing, petrochemical, power generation, and aerospace industries. It provides excellent weldability and produces clean and smooth welds with good penetration and low spatter. It can also be used for welding dissimilar metals, including nickel alloys, stainless steels, and carbon steels.
