Duplex 2205 ASTM A789 UNS S31803 Seamless Pipe

Duplex 2205 ASTM A789 UNS S31803 seamless pipe is a high-performance stainless steel pipe, and its details and features are as follows:

Material and Standard:

Material: Duplex 2205, also known as UNS S31803.

Standard: Conforms to ASTM A789, which is the standard for duplex stainless steel pipes established by the American Society for Testing and Materials (ASTM).

Material Properties:

Phase structure: Duplex structure, ferrite-austenite stainless steel, combines the best characteristics of austenitic and ferritic steels.

Corrosion resistance: Good resistance to stress corrosion cracking, pitting corrosion resistance is comparable to 317L, and has excellent corrosion resistance, which is much higher than 316 grade stainless steel.

Strength: It has high strength, and its yield strength is about twice that of standard austenitic stainless steel grades.
