The item is a precision alloy steel tube made from SAE 4140 (1.7225) chromium‑molybdenum steel, supplied by Sichuan Liaofu Special Steel Trading Co., Ltd. in Chengdu, China. The tubes are produced by cold‑drawing or cold‑rolling to achieve tight dimensional tolerances and are offered in seamless form for machining. The supplier notes compliance with ASTM, JIS, GB and EN DIN standards and can provide custom lengths according to drawing specifications.
Alloy 4140 is valued for its combination of high tensile strength, good toughness and excellent hardenability, making it suitable for demanding mechanical components. Typical industry dimensions for this grade range from 10 mm to 200 mm in outer diameter with wall thicknesses of 1 mm to 15 mm, although exact sizes are confirmed per order. The material’s chemical composition includes 0.38‑0.45 % carbon, 0.90‑1.20 % chromium, 0.15‑0.25 % molybdenum and other trace elements, delivering a minimum tensile strength of 1080 MPa and yield strength of 930 MPa after quench‑tempering.
Key buyers are manufacturers in automotive, aerospace, oil‑and‑gas and hydraulic systems that require machined components such as shafts, pistons and high‑stress fittings. Trade conditions are flexible, with the supplier indicating that pricing is direct from the factory and that packaging is arranged for safe transport. Importers should request a mill test report and verify surface finish quality before confirming the order.

Start by confirming the exact alloy grade, chemical composition and mechanical properties required for your component. Ask the supplier for a recent mill test report and copies of any ISO or other quality certificates that cover the SAE 4140 production process. Verify that the supplier can meet your dimensional tolerance and length specifications before finalising the purchase.
Discuss shipping arrangements early: agree on an Incoterm such as FOB Chengdu port and obtain an estimated lead time based on the order volume. Clarify payment terms, preferably using a letter of credit or escrow service to protect both parties. Ensure that the supplier provides a detailed packing list and bill of lading to avoid customs delays.
Plan for a third‑party inspection either at the factory or at the loading port to check surface finish, dimensional accuracy and material composition. An inspection report covering hardness, tensile strength and any required non‑destructive testing will support smooth customs clearance. Keep all certificates, inspection reports and shipping documents on hand for the import clearance process.
