I. Product Advantages
1. Superb Corrosion Resistance
Adopting a special formula, the deposited metal can resist stress corrosion cracking, pitting corrosion and other issues. It can work stably in harsh environments containing strong chemicals, seawater, chlorine gas, etc., extending the service life of equipment.
2. High Mechanical Strength
Tensile Strength: 115,000 psi (approximately 820-860 MPa)
Yield Strength: 90,000 psi (approximately 620-650 MPa) (under CO₂ shielding gas environment)
The weld can bear heavy loads and dynamic stresses, ensuring structural stability.
3. Excellent Welding Operability
Stable Arc: Easy to control during the welding process, reducing interruptions
Convenient Arc Striking: Excellent arc striking and re-striking performance, improving welding continuity
No Spatter: The weld bead is neat and aesthetic, reducing post-welding cleaning work
All-Position Applicable: Suitable for flat welding, horizontal welding, vertical welding and overhead welding (except vertical down welding for stainless steel), adapting to complex welding scenarios
4. Self-Releasing Slag Feature
The slag generated during welding can fall off automatically without additional effort for cleaning. The weld bead is smooth and free of defects, improving welding efficiency and quality.
II. Applicable Industries
1. Petrochemical Industry
Used for welding 22% Cr duplex stainless steel, it is suitable for the manufacturing and maintenance of oil pipelines, storage tanks, reaction vessels and other equipment. It resists erosion from highly corrosive substances and ensures production safety.
2. Marine Engineering Field
It can weld ship hulls, decks, superstructures and offshore platform structures. With strong seawater corrosion resistance, it ensures the long-term stable operation of marine equipment.
3. Water Treatment Industry
Used for welding stainless steel components such as pipelines, storage tanks and filtration systems in water treatment plants. It resists corrosion from chemicals like chlorine gas and ensures the reliability of water quality treatment.
4. Construction Structure Field
Suitable for welding duplex stainless steel components in projects such as buildings and bridges. The high-strength welds provide support for the structure, ensuring building safety and durability.
