Product Introduction

Carbon Steel Tube 20# is a versatile low-carbon steel product manufactured according to the Chinese GB/T 699 standard. It is widely recognized for its excellent balance of mechanical strength, ductility, and weldability. Available in both seamless and welded forms, as well as round, square, and rectangular profiles, this material serves as a fundamental component in modern industry. With a carbon content of approximately 0.20%, it offers superior plasticity for cold forming and reliable performance in structural and fluid transport applications.

Product Parameters

Product Features

• Excellent Mechanical Properties: 20# steel exhibits a tensile strength of ≥410 MPa and a yield strength of ≥245 MPa, providing robust structural support while maintaining an elongation of ≥25% for flexibility under stress.

• Superior Processability: The low carbon content ensures exceptional weldability and cold deformation plasticity. It can be easily bent, pressed, and machined without cracking, making it ideal for complex fabrication processes.

• Versatile Specifications: Available in a vast range of dimensions, with outer diameters ranging from small capillary tubes to large-diameter pipes (up to 36 inches or 3620mm) and wall thicknesses up to 65mm.

• Surface Variety: Can be supplied in various surface conditions including bright, polished, or black (hot-rolled), and supports extensive post-processing services such as heat treatment, annealing, and pickling.

Product Applications

• Structural Engineering: Widely used for manufacturing brackets, building frames, and construction supports due to its high strength-to-weight ratio.

• Machinery Manufacturing: Ideal for producing mechanical parts such as shafts, gears, bolts, and connecting rods that require good toughness.

• Fluid Transport: extensively used in piping systems for conveying water, oil, gas, and steam, thanks to its density and leak-proof integrity (especially seamless variants).

• Automotive & Agriculture: utilized in the fabrication of hydraulic cylinders and components for automotive and agricultural equipment where durability is essential.
