ASTM A790 , ASME SA790 S32205 Seamless Duplex Steel Pipes

YUHONG Group, a factory offers ASME SA790 / ASTM A790 S32205 SMLS duplex stainless steel pipes and we sell these pipes with high quality in more than 70 countries up to now.

ASTM A790/ ASME SA790 This specification covers seamless and straight-seam welded ferritic/austenitic steel pipe intended for general corrosive service, with particular emphasis on resistance to stress corrosion cracking. These steels are susceptible to embrittlement if used for prolonged periods at elevated temperatures.

Specifications

Advantages

ASTM A790 S32205 is a duplex stainless steel, which means it has a combination of both ferritic and austenitic microstructure. This makes it highly resistant to corrosion, especially in harsh environments such as offshore and marine applications.

ASTM A790 S32205 pipes have a high strength-to-weight ratio, making them suitable for use in structural applications where strength is important.

Due to their long service life, resistance to corrosion, and low maintenance requirements, ASTM A790 S32205 pipes are considered cost-effective in the long run.

ASTM A790 S32205 pipes exhibit good mechanical properties such as high tensile strength, excellent toughness, and good impact resistance.

These pipes can withstand a wide range of temperatures, from cryogenic temperatures up to high temperatures and have good weldability, which means they don't compromise their strength and corrosion resistance.

Overall, ASTM A790 S32205 pipes offer a combination of superior corrosion resistance, high strength, good weldability, and wide temperature range, making them a preferred choice for many industrial applications.
