The item is a steel round bar sheet plate supplied by Dongguan Songshun Mould Steel Co., Ltd., manufactured from AISI 4140 chromium‑molybdenum alloy steel. The alloy’s nominal composition is carbon 0.38‑0.43%, chromium 0.80‑1.10% and molybdenum 0.15‑0.25%, giving it medium hardenability and high fatigue strength. The supplier notes that the material complies with ASTM A29/A29M standards and is available in hot‑rolled or normalized conditions, but does not publish a minimum order quantity or unit price, so those details must be obtained directly from the exporter.
AISI 4140 is widely used for high‑stress components such as crankshafts, forging machine shafts and pressure‑vessel fittings because of its low notch sensitivity and excellent low‑temperature impact toughness. Typical heat treatment involves quenching followed by tempering, which yields a typical tensile strength of about 1000 MPa and a typical hardness of 28‑32 HRC. The supplier can provide custom cut‑to‑size dimensions, with typical thicknesses ranging from 5 mm to 50 mm and widths up to 2000 mm, and the material often finishes with a standard surface roughness of Ra 1.6 µm.
Importers in the oil‑and‑gas, heavy‑machinery and aerospace sectors frequently request this sheet plate for forged or welded assemblies that experience cyclic loading. Buyers usually specify dimensions, surface finish and heat‑treatment requirements, then arrange shipping under FOB or CIF terms. As the listing omits explicit trade conditions, interested parties should request a formal quotation that details packaging - commonly steel pallets wrapped in stretch film - and any required certifications.

When ordering this AISI 4140 sheet plate, first confirm that the supplier can provide a current mill test certificate showing chemical composition, tensile strength and compliance with ASTM A29. Request a sample or a third‑party inspection report to validate surface roughness and dimensional accuracy before committing to a large volume. Clarify whether the supplier can meet any specific heat‑treatment documentation required for your certification regime.
Shipping from Dongguan usually involves loading at the Shenzhen or Guangzhou ports. Importers should negotiate the preferred Incoterm, such as FOB Shenzhen, and verify the supplier’s accepted payment terms, for example a 30 % deposit and the balance payable against documents. Discuss container loading plans, pallet dimensions and any required export licences with the exporter to prevent customs delays.
Quality control should include a pre‑shipment inspection focusing on thickness tolerance, surface finish and hardness. Arrange for an independent inspection agency to issue a final test report, and ask the supplier for any existing ISO 9001 or similar quality management certificates. Maintaining clear inspection criteria and documentation will help ensure the material meets the stringent demands of high‑stress engineering applications.
