ERNiCrFe-3 Welding Wire Nickel-Chromium-Iron Alloy Welding Rod ERNiCrFe-3 For Re-Surfacing Steel

Production Description

ERNiCrFe-3 nickel-chromium-iron-nickel-based welding wire is a material that plays an important role in the field of welding. Its standard is SG-NiCr20Nb.

ERNiCrFe-3 is widely recognized as an important corrosion-resistant metal material. It has good resistance to corrosion by active gases, caustic media, and reducing acid media. It also has the characteristics of high strength, good plasticity, hot and cold deformation, processing and welding. These characteristics make it play a key role in many industrial fields such as petrochemicals, metallurgy, atomic energy, marine development, aviation, aerospace, etc., and can solve engineering corrosion problems that cannot be solved by general stainless steel and other metal and non-metal materials.

ERNiCrFe-3 Characteristics:

Outstanding corrosion resistance:

RNiCrFe-3 nickel-chromium-iron-nickel-based welding wire has excellent corrosion resistance and can resist corrosion from active gases, caustic media and reducing acid media. In practical applications, such as in the petrochemical industry, various corrosive media are often exposed. ERNiCrFe-3 welding wire can ensure long-term stable operation of the welding parts in such harsh environments. Data show that in certain specific corrosive environments, the service life of equipment welded with ERNiCrFe-3 can be extended by 2 to 3 times compared to equipment using ordinary welding wire. Its corrosion resistance comes from its special chemical composition, which can form a stable protective film on the metal surface to prevent the intrusion of corrosive media

Strength and plasticity:

ERNiCrFe-3 is not only strong, but also has good plasticity. This allows it to be hot and cold deformed and processed, and is also easy to weld. During the welding process, good plasticity can ensure that the weld is not easy to crack when stressed, and improve the reliability of the welded joint. For example, in the aerospace field, the strength and plasticity of the material are extremely high. This characteristic of ERNiCrFe-3 makes it an ideal welding material. Its high strength can withstand the stress of the aircraft in high-speed flight and complex environments, while its good plasticity can adapt to the deformation of the aircraft under different temperatures and pressures.

Applications:

Alloy 182 welding electrode can be used for countless applications. However more common applications include the chemical or petrochemical industries and the nuclear industry where it is used to weld dissimilar joints between vessels and primary piping. Alloy 182 is often used for welding the clad side of nickel-chromium-iron clad steel and for re-surfacing steel.

ERNiCrFe-3 can be used for welding of various alloys and surface cladding of steel, and is suitable for different working conditions. In terms of welding of dissimilar materials, it can achieve a perfect combination of different materials such as austenite, ferritic steel and high nickel alloy, overcoming the difficulties of traditional welding materials in welding dissimilar materials. In surface cladding of steel, it can significantly improve the performance and corrosion resistance of steel and extend the service life of steel. For example, in marine engineering, surface cladding of steel with ERNiCrFe-3 can effectively resist the corrosion of seawater and improve the reliability of marine engineering equipment. In the fields of metallurgy, atomic energy, etc., ERNiCrFe-3 is also widely used to meet the special requirements of materials in different working environments.
