TIG/MIG Nickel Alloy Welding Wires: AWS ERNiCrMo-10
Why choose our AWS ERNiCrMo-10 for PTA pipeline flange
AWS A5.14 AWS ERNiCrMo-10 Description:
ERNiCrMo-10 is a nickel-based welding wire under the AWS A5.14 standard. It exhibits strong resistance to pitting corrosion and stress corrosion cracking, capable of withstanding various corrosive media. Additionally, it maintains creep resistance at 315°C. The welding wire demonstrates excellent weldability, compatible with multiple welding techniques, and enables reliable joining of dissimilar metals. It also features high tensile strength and good ductility.
AWS A5.14 AWS ERNiCrMo-10 Application:
ERNiCrMo-10 welding wire is suitable for welding INCONEL 622 nickel-chromium-molybdenum alloy. It enables homogeneous welding between INCONEL and INCOLOY series nickel-based alloys, as well as dissimilar material welding between nickel-based alloys and carbon steel, stainless steel, etc. It can also be used for overlay welding to strengthen duplex stainless steels. In fields such as chemical engineering (equipment resistant to strong corrosive media), energy (nuclear power and thermal power components), and marine engineering (corrosion-resistant structures of offshore platforms), it is employed for manufacturing or repairing critical corrosion-resistant and high-temperature components due to its excellent corrosion resistance and high-temperature mechanical properties.

Thermal power generation units are power generation equipment that uses coal combustion as the primary source of power. The main process includes coal crushing and grinding, coal combustion to obtain heat energy and exchange heat with water, and water temperature rising to become high-temperature and high-pressure steam. Water vapor drives the turbine to rotate, which in turn drives the motor to generate electromagnetic induction power. Thermal power generation is developing towards large capacity, high parameters, low energy consumption, and environmental protection. The core materials for thermal power generation are high temperature resistant and corrosion-resistant materials. At 700 degrees Celsius, 617 grade nickel alloy material is required for the main pipeline. Nickel alloy laser cladding has a much higher efficiency than arc welding and can be used for maintenance of water-cooled walls. Nickel alloy and cobalt based alloys are used for the rotor, valve seat, and other structures of high-temperature gas turbines.

The valve body of oil/gas extraction equipment is the core component that controls the flow of oil and gas, and its performance directly affects the safety and efficiency of the equipment. Valve bodies are usually composed of valve bodies, valve seats, valve discs, valve stems, springs, and seals. Their main functions include controlling gas flow, regulating flow/pressure, sealing against leaks, and guiding gas direction. In harsh oil and gas extraction environments, valve bodies need to have characteristics such as wear resistance, corrosion resistance, and high temperature resistance. Therefore, welding technology is often used to strengthen the surface of valve bodies.

The continuous digester in papermaking equipment is the core equipment of pulp making process, mainly used to separate cellulose from other substances in raw materials. The evaporator body includes a heating chamber (boiler) and a separator. Common types include long tube rising film type (evaporation intensity 9-12kg/m ² · h) and short tube type. Multi effect evaporators can achieve energy efficiency of over 60% by reusing secondary steam heat energy, significantly reducing energy consumption. The selection of materials for its production needs to meet strict requirements such as high temperature resistance, high pressure resistance, and chemical corrosion resistance.
