Fe-Cr-Mo-B Welding Electrodes is a graphite type surfacing electrode, the surfacing metal is molybdenum chromium boron alloy, the hardness of the surfacing layer is HRC=60~65°, and the matrix is Cr7Mo6B8 dispersion hardening and toughening austenite. The surfacing metal is eutectic or near-eutectic alloy, the electrode not only has high temperature resistance (up to 650 ℃) but also wear resistance, toughness and crack resistance. Has high resistance to impact abrasive wear.
It is suitable for surfacing welding of wear-resistant parts in various industries such as steel mills, power plants, cement plants, casting plants, building materials plants, etc., and its welding life is 6~8 times higher than that of other materials.
Welding Rods are classified by use
1. Structural steel electrodes: including carbon steel electrodes and some low alloy steel electrodes
2. Chrome-Molybdenum Welding Electrodes: the weld metal of this type of electrode has different degrees of high temperature resistance.
3. Stainless steel electrode: The weld metal of this type of electrode has different degrees of anti-atmospheric or corrosion-resistant working ability at normal temperature, high temperature or low temperature.
4. Surfacing electrode: The surfacing layer of the weld metal surface of this type of electrode has different degrees of wear-resistant or corrosion-resistant working ability at room temperature or high temperature.
5. AWS E6013 Carbon Steel Welding Rod Welding Electrode: The weld metal of this type of electrode has a certain low temperature resistance working ability.
6. Cast Tungsten Carbide Tube Welding Rod: This type of electrode is used for welding or repairing cast iron.
7. Nickel and nickel alloy electrodes: This type of electrode is used for welding of nickel and nickel alloys, as well as for welding and surfacing of dissimilar metals.
8. Copper and copper alloy electrodes: This type of electrode is used for the welding of copper and copper alloys, as well as for the welding and surfacing of dissimilar metals, and the welding repair of cast iron.
9. Aluminum and aluminum alloy electrodes: These electrodes are used for welding, repairing and surfacing of aluminum and aluminum alloys.
10. Tungsten Carbide Tube Welding Rod Electrode
