Duplex S31803 structure and characteristics:
Duplex S31803 is dual-phase stainless steel showing combine properties of austenitic and ferritic structures. It is high strength ferrite grade enhanced with higher addition of Chromium with molybdenum and 40 to 50 ferrite percentage. Less sulphur in the alloy improves machinability. The austenitic grade feature of corrosion resistance is also upgraded with nickel addition.
- Double Strength
- Pitting resistant
- Crevice protection
- Chloride corrosion opponent
What are Duplex S31803 Forged Fittings?
Forged Fittings formed with Duplex grade S31803 are the best choice for lower expenses with stronger applications. It is intentionally developed to use in heavy industries. It is forged to obtain strength due to higher ferrite and thicker to sustain higher pressure in various applications. The austenitic duplex feature increases Threaded Coupling capability in corrosive surroundings. Forged Unions are immune to chloride decay, such as pitting and chloride stress that causes cracking. Excellent mechanical properties like higher tensile strength, low elongation and increased yield strength support the Socket Weld Elbows at intense stress and bearing loads. It illustrates qualities of:
- Workability
- Weldability
- Durability
- Antirust
- Leakage free

Duplex S31803 Forged Fittings are acid and sulphide corrosion resistant. It also prevents bio-attacks in marine with chloride decomposition. At higher temperature conditions, Socket Weld and Threaded fittings are excellent resistants to higher temperatures with an extensive working temperature range.
Duplex S31803 Forged coupling is easy to fix in a system with proper welding techniques. Forged Cross is a robust construction with dimensional accuracy. Whereas Duplex Forged Elbow gives optimum performance with low maintenance. The atmospheric effect after consistent use is less due to high Chromium and excellent surface finish.
