The product is a precision‑machined round bar made from AISI 5140 chrome‑molybdenum alloy steel, containing 0.38‑0.43 % carbon, 0.60‑0.90 % chromium and 0.15‑0.25 % molybdenum. Bars are supplied in diameters from 20 mm to 600 mm and lengths ranging between 1 000 mm and 6 000 mm, with a maximum plate thickness of 800 mm and a maximum width of 2 200 mm for custom cuts. The chemical composition is further limited to 0.37‑0.44 % C, 0.80‑1.10 % Cr and 0.15‑0.25 % Mo as per the listed specification.
The alloy belongs to the medium‑carbon cold‑heading family and is typically heat‑treated to achieve a combination of toughness and wear resistance, a standard practice for gear and bearing components. In the steel industry, 5140 is recognised for good tempering properties and is often supplied with a surface finish of black, polished or machined, which matches common surface‑treatment requirements. Typical industry tolerances for round bars of this size are ±0.2 mm on diameter and ±0.5 % on length, and a typical tensile strength after heat treatment lies between 800 and 1 000 MPa.
The bars are suited for automotive parts, machinery gear shafts, screws, nuts and other transmission components, making them a regular purchase for manufacturers of engines, gearboxes and mould equipment. The supplier lists a flexible minimum order of 5 tonne and a monthly capacity of 5 000 tonne, with container loading capacities of 28 tonne per 20 ft or 40 ft box and shipment from Shenzhen port within about 15 days after payment. Accepted payment terms include L/C, D/P and T/T, and packaging is described as seaworthy, allowing bulk orders to be consolidated for international freight.

Before placing an order, request the latest mill test report and chemical analysis to verify that the carbon, chromium and molybdenum levels fall within the specified ranges. Ask for a dimensional inspection certificate that shows compliance with the ±0.2 mm diameter tolerance and length tolerance, especially if the bars will be used for critical gear shafts. Confirm whether any additional standards such as ISO 9001 or specific automotive quality schemes apply to the batch you intend to purchase.
Logistics planning should include confirmation of the preferred Incoterm, typically FOB Shenzhen, and the expected lead time of around 15 days after payment receipt. Verify the exact shipping dimensions and container loading plan to avoid unexpected freight costs, and ensure that the payment method (L/C, D/P or T/T) matches your financing arrangements. It is advisable to discuss any required pre‑shipment inspections with the freight forwarder to align schedules.
Upon arrival, arrange a third‑party inspection that covers visual surface condition, dimensional checks and mechanical testing such as hardness or tensile strength, referencing the typical values of 800‑1 000 MPa. Request the original mill test report, heat‑treatment certificate and any applicable compliance documents before customs clearance. Maintaining these records will help you assess quality consistency for future orders from this supplier.
