Nickel welding wire is a type of metal welding material widely used in the field of welding, including various brands, such as ERNiCrMo-3, ERNiCrMo-4, ERNiCrMo-13, ERNiCrFe-7 and ERNiCr-3. Each grade of nickel wire has a unique alloy composition and welding properties suitable for different welding applications.
ERNiCrMo-3 is a high-alloy nickel welding wire with good corrosion resistance and high temperature stability. It is commonly used to weld high-alloy steel and nickel alloys in the chemical, petroleum and petrochemical industries.
ERNiCrMo-4 is a nickel-based alloy welding wire with excellent corrosion resistance and high temperature performance. It is suitable for welding stainless steel and nickel-based alloys and is commonly used in the chemical, marine engineering and nuclear industries.
ERNiCrMo-13 is a high-alloy nickel welding wire that performs well in welding corrosion-resistant alloys, high-temperature alloys and acid-resistant stainless steel, and can meet the requirements of harsh working environments.
ERNiCrFe-7 is a nickel-iron-based alloy welding wire, suitable for welding stainless steel, alloy steel and high-temperature alloys, with good corrosion resistance and high temperature performance.
