The product is a hot‑rolled flat bar and plate made from AISI 4340 / 36CrNiMo4 Nickel Chromium Molybdenum alloy steel, supplied by Dongguan Songshun Mould Steel Co., Ltd. in China. Grade 4340 provides a combination of high tensile strength, toughness and fatigue resistance that meets the needs of demanding engineering applications. The material is delivered with a black, hot‑rolled surface and is noted for good machinability. It conforms to the standard specifications used by aerospace, oil‑and‑gas and heavy‑machinery sectors.
In the steel industry 4340 is typically supplied in thicknesses from 5 mm to 200 mm and widths up to 2000 mm, with dimensional tolerances of ±0.5 mm on thickness and ±1 mm on width. Standard heat treatment is quenching followed by tempering, which yields a typical tensile strength of about 1080 MPa and a hardness of 30‑38 HRC. The alloy is covered by standards such as ASTM A322 and EN 10149, and manufacturers often hold ISO or SGS certification, which should be verified with the supplier.
Typical end‑uses include aerospace structural components, drilling equipment for oil and gas, heavy‑duty machinery parts and automotive shafts or gears. Dongguan Songshun offers flexible minimum order quantities and ships the product in palletised wood crates wrapped in protective film. The supplier mentions that payment can be made by L/C or T/T and that incoterms such as FOB or CIF are negotiable, so buyers should confirm the exact trade terms before placing an order.

Before placing an order, verify the supplier’s trade credentials, request a recent mill test certificate and confirm that the material complies with the required ASTM or EN standard. Because the response rate is recorded as zero, initiate contact early and ask for references or third‑party audit reports to ensure reliability.
Discuss logistics in detail: confirm the nearest loading port in China, agree on the incoterm (FOB, CIF or other), and obtain an estimated lead time for production and shipment. Payment methods such as L/C or T/T should be aligned with your company’s risk policy, and any bank charges or documentary requirements need to be clarified upfront.
Arrange for a pre‑shipment inspection by an accredited third‑party agency and request the inspection report, mill test certificate and any relevant quality certificates. Ensure that the packaging is suitable for the dimensions of the flat bars and that the crates are sealed properly for ocean freight. Proper documentation will streamline customs clearance and reduce the risk of delays.
