The 27SiMn thick wall cold drawn seamless tube is a low alloy steel product with a silicon content of 1.10 to 1.40 percent and manganese of 1.10 to 1.40 percent, designed for applications demanding high tensile strength and durability. Its carbon range of 0.24 to 0.32 percent ensures a balance between hardness and weldability, making it suitable for hydraulic cylinder and machinery manufacturing. Produced to GB/T 17396 or equivalent standards, this tube is cold drawn to achieve tighter dimensional tolerances and a superior surface finish compared to hot rolled alternatives.
Material composition is critical for performance, with silicon and manganese enhancing strength and resistance to impact, while the cold drawing process refines the grain structure for improved mechanical properties. Typical industry grades for similar tubes include ASTM A519 for seamless mechanical tubing, though this specific product adheres to Chinese standards. The thick wall design allows for higher pressure resistance, a key requirement in hydraulic systems and heavy machinery.
This tubing is widely used in automotive applications, construction equipment, and industrial machinery where reliability under stress is non-negotiable. Buyers typically source it in bulk for large-scale projects, with packaging and logistics tailored to long-distance shipping. Confirmation of exact dimensions, wall thickness, and length tolerances is advised, as these can vary based on production batches and custom orders.

Before ordering, verify the tube’s exact dimensions, including outer diameter, wall thickness, and length, as these can impact compatibility with your machinery or hydraulic systems. Request a copy of the mill test certificate to confirm the material composition and mechanical properties, ensuring they meet your project’s requirements.
Confirm the supplier’s lead times, as cold drawn seamless tubes may require additional processing time compared to hot rolled alternatives. Discuss Incoterms such as FOB or CIF to clarify responsibility for shipping costs, insurance, and delivery to your port. Payment terms should also be negotiated, with options like TT or LC typically used for bulk orders.
Inspect the tubes upon arrival for dimensional accuracy, surface defects, and straightness, as cold drawn products can sometimes exhibit minor imperfections. Request third-party inspection reports if needed, and ensure all documentation, including packing lists and certificates of origin, is in order to facilitate customs clearance.
