EutecTrode XN 2222 Nickel-Based Welding Rod, Super 680 CGS Tool Steel Welding Rod, Germany Kastolin

Germany Kastolin XHD223 3N Cast Iron Electrode

• Product Overview: This is a low-temperature manual arc welding electrode used for repairing high-strength cast iron and joining cast iron to steel. It offers extremely high crack resistance, effectively preventing crack formation during welding; it also provides high tensile strength and elongation, ensuring excellent mechanical properties in both the weld and heat-affected zone. It exhibits good weldability and superior operability with both DC and AC welding.
• Main Composition: Contains elements such as Ni, Fe, and Mn. Among these, nickel (Ni) enhances the electrode's crack resistance and toughness; iron (Fe) serves as the fundamental component, ensuring weld strength; manganese (Mn) improves wear resistance and toughness of the weld.
• Typical Applications: Suitable for welding cast iron and malleable fittings such as valve pistons, pressure tanks, and water tanks; also commonly used for repair work like filling holes and defects in hydraulic pressure tanks and various castings.
• Specifications and Dimensions: Common sizes include Ф2.5mm, Ф3.2mm, and Ф4.0mm.
• Current Range: The Ф2.5mm electrode is suitable for a current range of 50 - 90A; Ф3.2mm for 80 - 120A; and Ф4.0mm for 100 - 150A.
• Mechanical Properties: Tensile strength is 480 - 550MPa, yield strength is 300 - 350MPa, and hardness HV30 is 165.

Germany Kastolin EC33700 Stainless Steel Electrode

• Product Overview: This is an electrode suitable for welding dissimilar steels, stainless steels, high-alloy steels, and heat-resistant steels. It offers high heat resistance, maintaining excellent performance in high-temperature environments up to 1000°C, along with superior corrosion resistance against various corrosive media.
• Main Composition: Primarily contains alloying elements such as Cr, Ni, and Mo. Chromium (Cr) is a crucial alloying element in stainless steel, enhancing corrosion and oxidation resistance; nickel (Ni) improves toughness and corrosion resistance, boosting the electrode's overall performance; molybdenum (Mo) further enhances corrosion resistance, particularly against chloride ions.
• Typical Applications: Commonly used for welding high-temperature equipment such as furnace linings, furnace components, boilers, and heat treatment furnaces; also applied in welding corrosion-resistant parts like submarines, discharge pumps, and hanging baskets.
• Specifications and Dimensions: Available in sizes such as Ф2.0mm, Ф2.5mm, Ф3.2mm, and Ф4.0mm.
• Mechanical Properties: Tensile strength is 638MPa, yield strength is 496MPa, elongation is 37.2%, and hardness HV30 is 220.
