ASME SA268 TP410 seamless stainless steel pipe for boilers
ASME SA268 TP410 seamless stainless steel pipe for boilers
ASME SA268 TP410 seamless pipe is a martensitic stainless steel suitable for boilers due to its high strength, good heat resistance, and ductility, but its corrosion resistance is limited compared to austenitic stainless steels. Its key properties include magnetic properties, a specific chemical composition (for example, a chromium content of 11.5% to 13.5%), and mechanical properties such as a minimum tensile strength of 480 MPa and a minimum elongation of 16%. These pipes must meet the rigorous testing requirements specified in the ASME SA268 standard, such as hydrostatic testing, ultrasonic testing, and hardness testing, to ensure safety and performance in high-temperature applications.
What is 410 grade stainless steel?
410 stainless steel is a martensitic stainless steel known for its high strength and hardness, which can be achieved through heat treatment. It offers good corrosion resistance in mild environments and is suitable for applications requiring a balance of wear resistance, strength, and toughness, such as in the automotive and power generation industries. It is also highly magnetic.
ASME SA268 TP410 Seamless Stainless Steel Pipe
ASME SA268 TP410 seamless stainless steel pipe is a widely used martensitic stainless steel pipe known for its moderate corrosion resistance, high strength, and high hardness. Manufactured seamlessly, this pipe ensures structural integrity in pressure-containing applications. Typically supplied in heat-treated conditions (such as annealed or quenched and tempered) to achieve the desired mechanical properties, it is suitable for a variety of industrial applications, including steam systems, oil well tubing, heat exchangers, and mechanical components.
TP410 is a basic martensitic chromium stainless steel with a chromium content of approximately 11.5%, providing corrosion resistance in mild environments. Unlike austenitic stainless steels such as 304 or 316, TP410 is magnetic and can be strengthened through heat treatment. Its final properties are largely determined by the heat treatment condition.

Applications and Advantages
Boiler: Due to its high-temperature strength and strength-to-weight ratio, it can be used in boilers and other high-temperature applications.
High-Stress: It performs well under high-stress conditions.
Seamless Construction: Seamless pipes are preferred for high-pressure applications because they eliminate the risk of seam rupture and are generally considered to offer better pressure resistance than welded pipes.
Cost-Effective: They are often used in applications that require a balance between performance and cost.
Manufacturing and Standards
Standards: ASME SA268 covers the specifications for this type of stainless steel pipe.
Manufacturing Process: Seamless pipes are heated, pierced, and rolled from solid billets into hollow tubes.
Testing Requirements: They must meet stringent testing requirements specified by the standard, including:
Hydrostatic testing
Non-destructive electrical testing (e.g., ultrasonic testing)
Mechanical testing (e.g., flaring, hardness testing)
Marking: Pipes should be labeled with details such as grade, standard, size, batch number, and length.
Gnee Steel specializes in the production of a wide range of stainless steel products. Gnee Steel's product packaging includes: Steel Strapping: Pipes with an outer diameter of 3 inches or less are typically strapped together with polypropylene film to prevent rust during ocean shipping, and then secured with steel strapping. Wooden Cases/Crates: Pipes are typically packaged in wooden cases or crates to protect the pipes during transportation, especially those that are longer or have larger diameters. Seaworthy Export Packaging: Suppliers typically use standard seaworthy export packaging methods, which may include a variety of materials and techniques to protect the pipes during transportation. Tarpaulin Packaging: This prevents rain, seawater, and other external factors from penetrating the export crates during transportation. Gnee Steel specializes in the production and sale of alloy materials. Gnee Steel's products are widely used in the aerospace, chemical, power, automotive, and nuclear energy sectors, and we can provide customized alloy material solutions based on customer needs.
