Introduction
ASTM A790 S32205 Duplex Stainless Steel Seamless Pipe is a high-strength, corrosion-resistant pipe combining the properties of both austenitic and ferritic stainless steels. DLSS supplied DN20 SCH10S seamless pipe, 550 mm length, manufactured to ASTM A790, specially packed and shipped by air to Australia for urgent project requirements.
The short length and fast delivery highlight DLSS’s ability to provide flexible logistics solutions and ensure on-time project support for clients worldwide.
Key Properties of Duplex S32205 Seamless Pipe
-
High Strength – approximately twice the yield strength of standard austenitic stainless steel (e.g., 316L).
-
Excellent Corrosion Resistance – superior resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-rich environments.
-
Balanced Microstructure – austenitic + ferritic structure offers excellent toughness and mechanical properties.
-
Versatile Applications – ideal for oil & gas, desalination, offshore platforms, and heat exchangers.
-
Cost-Effective – lower nickel and molybdenum content compared with super austenitic grades, but with equal or better performance.
