Duplex Steel 2205 Electrodes

About Duplex Steel 2205 Electrodes

Duplex Steel 2205 Electrodes are composed of various chemical elements, including chromium, molybdenum, manganese, nickel, and nitrogen. This unique blend of alloys provides incredible strength, durability, and excellent corrosion resistance to Duplex Steel 2205 Electrodes. The high levels of chromium give these electrodes outstanding resistance to pitting and crevice corrosion, while nitride enhances their impact toughness at sub-zero temperatures. Molybdenum helps to increase the ability of Duplex Steel 2205 Electrodes to withstand hard surfaces while still maintaining good formability.

Versatility for Demanding Environments

Duplex Steel 2205 Electrodes are designed to excel in various aggressive settings, from offshore structures to chemical processing plants. Their unique duplex microstructure ensures high resistance to stress corrosion cracking, making them a dependable choice for fabrication and repair in the oil & gas, marine, and petrochemical sectors. With the ability to weld in all positions, these electrodes add flexibility and efficiency to complex projects.


Outstanding Mechanical and Corrosion Properties

Achieving a minimum yield strength of 550 MPa and tensile strength over 750 MPa, these electrodes deliver robust joints that withstand mechanical stress and harsh environmental conditions. The combination of chromium, molybdenum, and nitrogen in their composition ensures superior resistance to pitting and crevice corrosion, while also maintaining excellent impact toughness at temperatures as low as -40C.


Simplified Handling and Storage

Supplied in sealed, moisture-proof boxes, Duplex Steel 2205 Electrodes maintain low hydrogen levels for high crack resistance, even after prolonged storage. For best results, store electrodes below 60% relative humidity in a dry environment. With their polished core and flux-coated finish, they provide a stable arc and smooth, spatter-free welds across all standard electrode diameters.
