Guizhou Jingyang Trading Co., Ltd offers forged crankshafts made from 4340 or 4140 steel and ductile iron EN‑GJS‑600, engineered to meet OEM specifications for passenger‑vehicle and commercial diesel engines. The components conform to ISO and ASTM standards and are supplied with flexible minimum order quantities and freight‑ready packaging. Each shaft is precision‑machined to ensure balanced rotation and long service life under high‑stress conditions.
In the automotive sector, forged 4340 steel is a common grade because of its excellent tensile strength and fatigue resistance; typical heat‑treatment involves quench and temper to achieve a Rockwell C hardness of 45‑55. Dimensional tolerances are usually held within ±0.03 mm on journal diameters, and surface finishes are milled to a Ra ≤ 1.6 µm. These industry norms help maintain bearing clearances of 0.001‑0.003 mm and support weights around 12 kg for a 250 mm crankshaft.
The shafts are suitable for OEM production lines, aftermarket rebuild shops, and high‑performance tuning firms that require reliable power transmission. Trade terms commonly include FOB or CIF shipping from the port of Guangzhou, with payment via L/C or T/T as agreed. Buyers should request the ISO certification and any third‑party test reports to confirm compliance before finalising the purchase.

Before placing an order, confirm the exact material grade, dimensional tolerances, and any required certifications such as ISO 9001 or ASTM test reports. Request a detailed drawing that includes journal diameters, keyway dimensions, and surface finish specifications to avoid mismatches during production.
Logistics for this supplier typically involve FOB terms from the nearest Chinese port, with CIF options available upon request. Verify the expected lead time, which depends on order size and any required heat‑treatment cycles, and agree on payment methods like L/C or T/T that suit both parties.
Quality assurance should include an on‑site inspection or a third‑party audit, especially for high‑stress engine components. Arrange for a pre‑shipment sample if possible, and request the final inspection report that confirms hardness, dimensional compliance, and surface integrity before the goods are released.
