Duplex Steel Filler Wire

Duplex Steel Filler Wire is a welding material used in welding duplex stainless steel, a blend of austenitic and ferritic stainless steel. As a material with a balanced composition of austenite and ferrite, the duplex steel's microstructure makes it strong, corrosion resistant, and durable. This filler wire is critical in producing sound welds that possess the duplex stainless steel's mechanical and corrosion-resistant characteristics. Applied in oil, gas, chemical processing, marine, and construction industries, Duplex Steel Filler Wire provides durability for welded joints in severe conditions.

Advantages of  Duplex Steel Filler Wire

These flexible  Duplex Steel Filler Wires offer numerous benefits for industrial applications.

• Excellent Corrosion Resistance: Duplex stainless steel's resistance to pitting, crevice corrosion, and stress corrosion cracking makes the filler wire suitable for corrosive atmospheres.
• High Strength: The duplex microstructure improves strength over the more conventional stainless steel, leading to enhanced and lighter designs in engineering applications.
• Good Weldability: The Duplex Steel Filler Wire is designed to be easily welded so that there is very little chance of weld defects such as cracking occurring.
• Reduced Heat Input: Duplex Steel Filler Wire has been developed to allow low heat input during welding. This will eliminate the formation of undesired phases in the weld zone.
• Versatility: Duplex Steel Filler Wire can be used for MIG, TIG, and submerged arc welding, so it is versatile in usage.
• Good Toughness: Retains rigidity at low temperatures for applications where temperature fluctuation is expected.
• Cost-Effective: Duplex steel is highly strong and corrosion resistant, so its use can mean lower maintenance and replacement costs in the long run.
• Improved Resistance to Sour Environments: Proper in application where hydrogen sulfide (H2S) is involved, thus useful in the oil and gas sector.
• Low Carbon Content: Duplex Steel Filler Wire usually contains less carbon, which helps prevent carbide formation that might otherwise lower corrosion resistance.
• High Mechanical Properties: The welds possess highly desirable mechanical characteristics in the industry.

Duplex Steel Filler Wire offer several advantages that make it suitable for industrial and commercial applications.
