Understanding ASTM A240 / ASME SA-240
What It Is:
ASTM A240 / ASME SA-240 is the definitive standard for the duplex steel plate used to create high-integrity welded pipes.
The Material Blueprint: It governs the precise chemical balance and two-phase (austenite-ferrite) microstructure that gives Duplex 2205 its unique properties.
Mandates Mechanical Strength: The standard specifies the high tensile and yield strength requirements, a key advantage of Duplex 2205 over standard austenitic grades.
Foundation of Quality: It is the primary quality document for the raw material, ensuring that every welded pipe begins with fully certified and compliant plate.
Why It Is Your Core Focus:
Our unwavering focus on this standard is our commitment to delivering guaranteed performance, safety, and reliability in every pipe.
Guaranteed Corrosion Performance: Compliance ensures the correct microstructure for superior resistance to chloride stress corrosion cracking (SCC), pitting, and general corrosion.
High Strength for Design Efficiency: Adherence guarantees the mechanical properties that allow for lighter, thinner-walled, and more cost-effective designs in structural and process applications.
Assured Compliance & Traceability: It provides the basis for the Material Test Certificate (MTC), giving you verifiable proof that your pipes meet all project and regulatory requirements.
