Description

ASME B16.9 Buttweld Pipe Fitting ASTM A815 WPS31803 Duplex Steel 90 Degree Elbow


S31803 stainless steel, also known as 2205 stainless steel, has a dual-phase microstructure consisting of roughly equal parts of austenite and ferrite phases. It is a popular grade of duplex stainless steel, the unique structure contributes to its excellent combination of mechanical strength and corrosion resistance properties. It can be easily welded using common welding techniques and does not require pre- or post-weld heat treatment in most cases. While duplex stainless steel may have a higher initial cost compared to austenitic stainless steels, the long-term cost-effectiveness of S31803 elbows is notable due to their extended service life and reduced maintenance requirements.

Some key features of duplex steel elbows include:

  1. Corrosion Resistance: Duplex stainless steel offers excellent corrosion resistance, especially in harsh environments with high chloride content.

  2. High Strength: Duplex steel has higher strength compared to standard austenitic stainless steels, making it suitable for high-pressure and high-temperature applications.

  3. Good Weldability: Duplex steel elbows can be easily welded using common welding techniques, making them versatile for various piping configurations.

  4. Resistance to Stress Corrosion Cracking: Duplex steel is known for its resistance to stress corrosion cracking, which is a common issue in chloride-rich environments.

  5. Versatility: Duplex steel elbows are available in different sizes, schedules, and angles to accommodate a wide range of piping systems and applications.

  6. Cost-Effective: Despite being a premium material, duplex steel can offer cost savings over the long term due to its durability and lower maintenance requirements.

Applications
