Super Duplex Steel Filler Wire

Super Duplex Steel Filler Wire is a welded wire with a higher percentage of austenite and ferrite phases. The enhanced microstructure of this material imparts super duplex steel with high strength, corrosion resistance and durability to serve in various industries. The filler wire is essential in obtaining sound welds that possess the desired mechanical characteristics and resistance to corrosion of super duplex stainless steels. It has the reliability and durability of welded joints that are exposed to aggressive environments.

Features of Super duplex steel filler wire

Super duplex steel filler wire is one of the most used filler wires because of the following reasons:

• Exceptional Corrosion Resistance: Super duplex stainless steels have high resistance to pitting, crevice corrosion and stress corrosion cracking.
• High Strength: Super duplex steel has a higher yield and tensile strength and thus can support lighter structures.
• Good Weldability: This filler wire is developed to offer good weldability with low chances of defects, therefore guaranteeing sound and consistent welding outcomes.
• Lower Heat Input: Super Duplex Steel Filler Wire provides low heat input during welding, minimising the generation of unwanted phases that can compromise weld quality.
• Versatility in Welding Processes: Super duplex steel filler wire is versatile in the range of applications for MIG/TIG welding and submerged arc welding, which offers versatility in use.
• Improved Resistance to Sour Environments: This filer wire is useful where hydrogen sulfide (H2S) is present and ideal for industries where improved resistance is required.
• Reduced Risk of Sensitization: The low carbon content in the filler wire reduces the possibility of carbide formation thereby improving general corrosion characteristics.

Super duplex steel filler wire offers several advantages that make it suitable for industrial and commercial applications.
