ASTM A554 Polished TP304 Stainless Steel Welded Decorative Round Tube
ASTM A554 TP304 stainless steel welded decorative round tube is a mechanically grade welded tubing that is durable, corrosion-resistant, and polished for aesthetic applications. It is made from flat-rolled steel, welded without filler, and then cold-worked to increase strength and meet dimensional tolerances. This special tubing, made of 304 stainless steel, is suitable for decorative and structural applications where high aesthetics are required, such as handrails, building components, and marine hardware.
What is TP304 stainless steel?
This type of pipe is used in high-temperature environments. Due to the addition of titanium and molybdenum to its composition, TP304 stainless steel pipe conforming to ASTM A312 standards has higher strength and greater corrosion resistance. Our ASTM A312 TP304 EFW pipes are manufactured using an electrofusion welding process, making them less prone to localized corrosion.
ASTM A554 TP304 Polished Stainless Steel Welded Tube/Decorative Tube
ASTM A554 is a specification for welded stainless steel mechanical tubing. It covers round, square, rectangular, and irregularly shaped tubing. A significant feature of ASTM A554 is the requirement for cold working of the weld seam after welding, thereby improving the overall strength and durability of the tubing.
In addition to the cold working requirement, ASTM A554 also specifies that the tubing must be straightened and polished using a cold drawing process. This helps ensure dimensional consistency and a smooth surface.
ASTM A554 tubing is commonly used in applications requiring high corrosion resistance, such as the food and beverage industry or marine environments. This is because stainless steel has extremely high corrosion resistance and can withstand the erosion of corrosive chemicals and saltwater.
This tubing is available in a variety of sizes and wall thicknesses to suit a wide range of applications. It can be used for structural support as well as decorative purposes, such as handrails, balustrades, and architectural features.
Materials and Manufacturing
Materials: The tubing is made of 304 stainless steel, renowned for its high corrosion resistance and strength.
Welding: Automated welding processes are used, directly welding flat-rolled steel without the need for filler metal.
Cold Working: After welding, the weld seam is cold-worked, and a cold-drawing process is used to smooth the tubing surface, improving its strength and durability, and ensuring dimensional consistency and a smooth surface.
Product Specifications
Shape: The tubing is round, but ASTM A554 also covers square, rectangular, and special shapes.
Surface Finish: "Polishing" refers to surface finishes for decorative and aesthetic purposes, with grit ranging from low to high grit mirror polishing.
Dimensions: This standard covers tubing with an outer diameter of 16 inches (406.4 mm) and a wall thickness of 0.020 inches (0.51 mm) and above.

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.
