The EN/DIN Standard Alloy Round Bar offered by Big Co., Ltd. is manufactured from alloy steel conforming to EN and DIN grades such as 42CrMo4, 4140 and 4340. Diameter sizes are supplied from 10 mm up to 500 mm and lengths can be ordered between 1,000 mm and 6,000 mm. The product meets the full suite of international standards including AISI, ASTM, BS, DIN, GB and JIS. It is hot-rolled and prepared for machining, providing the strength required for demanding components.
Alloy steel of this class typically delivers tensile strengths approaching 1,200 MPa for the 42CrMo4 grade, with a hardness range of 30-35 HRC after normalising. Surface finish is commonly specified to Ra 0.8 µm, and diameter tolerances of +/-0.2 mm are standard for precision shafts. These characteristics align with industry expectations for automotive, machinery and oil-and-gas applications where fatigue resistance is critical. The material composition offers good toughness and wear resistance, making it suitable for shafts, gears and bolts.
Primary buyers include manufacturers of automotive drivetrains, heavy-duty machinery and oil-field equipment who require reliable round bar stock. Big Co., Ltd. ships the bars from China with flexible packaging options such as bundled pallets or shrink-wrapped bundles, and can arrange FOB or CIF terms according to the buyer's preference. Minimum order quantities are not fixed in the listing, allowing both small-scale and bulk purchasers to place orders. Prospective importers should request the mill test certificate and confirm lead-time before finalising the contract.

Before placing an order with Big Co., Ltd., verify that the alloy grade, diameter and length match your engineering drawings. Request the mill test certificate and any applicable standard compliance documents, such as ASTM or DIN test reports, to ensure the material meets the required mechanical properties. Confirm that the supplier can provide the exact tolerance and surface finish you need, and clarify any special heat-treatment or coating requirements.
Logistics should be arranged based on the buyer's preferred Incoterm; the supplier can ship on FOB or CIF terms from ports in China. Discuss container loading plans, whether the bars will be bundled on pallets or shrink-wrapped, and confirm the total weight per container to avoid unexpected freight charges. Payment conditions are not listed, so negotiate standard B2B terms such as T/T in advance or a documentary letter of credit, and obtain a pro-forma invoice before shipment.
Implement a third-party inspection either at the factory or prior to loading to verify dimensions, surface roughness and material composition against the supplied certificates. Request a pre-shipment inspection report and a final quality assurance certificate confirming compliance with
