Due to its higher allowable carbon content, Duplex Steel 329 Fasteners is the first duplex steel. For exceptional corrosion resistance and strength in mild temperatures, AISI 329 Stainless Steel is the material of choice.
Duplex Steel 329 Fasteners It can be utilized for hydraulic cylinders in marine applications or any place strong corrosion resistance is required. In environments with chloride, in particular, it offers very strong corrosion resistance. Additionally, it increases resistance to fatigue corrosion, stress corrosion, and pitting corrosion. It is distinct for its strength, flexibility, and hardness. It must be welded with as little heat as feasible. Compared to UNS S32205, UNS S32900 stainless steel has a somewhat lower alloy concentration. It becomes brittle at high temperatures of 300 to 900 °C. Through the use of welding supplies, it can be welded.
Applications:
- Warmth exchangers
- Tanks for chemicals
- The refineries
- Pressure vessel shafts (marine)
- Oil and Gas Industry Flanges, Fittings, and Pipes
- Online Technology
- Paper Business
- Compressor components
- Plants that desalinate seawater
Features
• One of the precipitation-hardening grades that are most frequently utilized in the industry.
• Even though it is ductile and soft in the solution-annealed state, it can achieve high characteristics with just one precipitation or aging treatment.
• Displays strong toughness, high harness, and good corrosion resistance
Machinability
- This alloy's machinability is characterized by its long, gooey chips.
- Although the annealed state can be used for machining, condition H1150M will produce the best results.
- If machining in this state, post-machining solution treatment of the parts will be necessary before final hardening.
Welding
• Although this alloy can be successfully welded using standard fusion and resistance techniques, oxyacetylene welding is not recommended.
• If necessary, AWS E/ER630 infill metal is advised.
