Butt-welding Concentric Reducer 10" x 6" STD ASTM A815 UNS S32202 Duplex Stainless Steel

Butt-welding Concentric Reducer 10" x 6" STD ASTM A815 UNS S32202 Duplex Stainless Steel

Duplex stainless steel is a type of stainless steel that combines both austenitic and ferritic microstructures, offering excellent mechanical properties and corrosion resistance. Its unique dual-phase structure provides outstanding resistance to chloride stress corrosion cracking, high strength, and it widely used in industries such as oil & gas, chemical processing, and marine engineering.

Product Applications
Duplex stainless steel is widely used in the following industries:

1. Oil & Gas: Subsea pipelines, valves, pressure vessels

2. Chemical Processing: Reactors, heat exchangers, storage tanks

3. Desalination: Pumps, piping systems

4. Energy & Environmental: Flue gas desulfurization (FGD) systems, wastewater treatment equipment

Product Advantages
1. High Strength: Higher yield strength than standard austenitic stainless steel, reducing material usage and costs.
2. Superior Corrosion Resistance: Ideal for chloride-rich environments (e.g., seawater, chemical media).
3. Good Weldability: Maintains high corrosion resistance and mechanical properties after welding.
4. Cost-Effective: More economical than high-nickel austenitic stainless steels (e.g., 316L).

Product Features
1. Corrosion Resistance: Resists pitting, stress corrosion, and intergranular corrosion.

2. High Strength: Suitable for high-pressure and high-load environments.

3. Wear Resistance: Ideal for transporting abrasive media.

Precautions
1. Avoid Prolonged High-Temperature Exposure.
2. Prevent Contamination: Avoid contact with carbon steel during processing to prevent iron contamination.
3. Material Selection: Different grades suit different environments (e.g., 2205 for general corrosion, 2507 for harsher conditions).
