Products Description
ENiCrCoMo-1 is a nickel-based alloy electrode with the standard model AWS A5.11. Its weld metal has the advantages of high strength, high metallurgical stability, corrosion resistance and high temperature oxidation resistance. It is mainly used for welding nickel-based alloys such as INCONEL617, INCOLOY800, INCOLOY800H, etc. It can also be used for welding HP45 alloy and other heat-resistant casting alloys themselves and between them, and can also be used for welding forged or cast copper-nickel alloys, specific bronze materials, etc. The working temperature of the joint can reach 2100°F (about 1149℃). In addition, it is also suitable for welding martensitic steel, ferritic steel and high nickel alloys, as well as surface surfacing of steel.
Products Description
Ordinary welding materials cannot withstand extreme welding scenarios with high temperature above 1100℃, high pressure and complex corrosive media? No problem, we have ENICrCoMo-1. As a high-performance nickel-based alloy welding rod, it has become a key connection material in many industrial fields with "almost harsh" requirements on welding quality due to its core advantages of high temperature resistance (can withstand high temperature above 1100℃ for a long time), strong corrosion resistance and high strength.
Energy and power field
Gas turbine hot end component welding
The core components of gas turbines, such as combustion chambers, transition sections, and turbine blades, are exposed to extreme environments of high-temperature gas erosion (temperatures often exceeding 1000°C) and high pressure (tens of atmospheres) for a long time, and need to resist corrosion from sulfides, nitrogen oxides, etc. in the gas. ENiCrCoMo-1 welded joints can maintain stable strength under such conditions without embrittlement or oxidation failure, and are the "welding shield" that ensures the long-term and efficient operation of gas turbines.
Chemical and petrochemical fields
High-temperature reactor and pipeline welding
In the chemical industry, high-temperature reactors (working temperature 800-1200℃) and cracking furnace pipelines for processes such as synthetic ammonia and methanol need to be exposed to corrosive media such as hydrogen, carbon monoxide, acid and alkali. ENiCrCoMo-1 can effectively resist the corrosion of these media, while maintaining the sealing and strength of the welded joints at high temperatures, avoiding production accidents or raw material losses caused by weld leakage.
Aerospace and Specialty Industries
Aircraft engine component welding
The combustion chamber, tail nozzle and other components of aircraft engines have high operating temperatures and large vibration loads, and have extremely high requirements for lightweight materials and reliability. The joints welded with ENiCrCoMo-1 have high strength and good toughness, and can adapt to the drastic temperature changes during engine start-up and shutdown (rapid switching from room temperature to more than 1000℃), ensuring flight safety.
