Chinese Competitive Steel 4140
The product is a chromium‑molybdenum alloy steel grade designated AISI 4140, offered by Dongguan Songshun Mould Steel Co., Ltd. in China. Its chemical composition ranges from 0.38~0.45 % carbon, 0.17~0.37 % silicon, 0.50~0.80 % manganese, up to 0.025 % each of phosphorus and sulfur, 0.9~1.2 % chromium and 0.15~0.25 % molybdenum. The alloy complies with AISI/SAE 4140, ASTM, GB, DIN and JIS 42CrMo standards and is marketed for oil‑and‑gas, machinery and automotive components.
In typical industry practice 4140 is supplied quenched and tempered to reach a tensile strength of about 930 MPa and a hardness of 28‑32 HRC. The medium carbon level gives a balance of ductility and wear resistance, making it a standard choice for high‑stress parts. Dimensional tolerances are usually ±0.2 mm for bar diameters up to 25 mm and ±0.3 mm for larger sizes. The material is normally packed in bundled steel packs on pallets, wrapped to protect against moisture.
Common applications include drill collars, gears, connecting rods, pump shafts and tool holders where fatigue performance is essential. Importers such as equipment manufacturers and oil‑field service firms source this grade for its consistent chemistry and competitive cost. Dongguan Songshun Mould Steel indicates bulk shipments are arranged under FOB or CIF terms, with packaging in standard bundles. Prospective buyers should verify the required heat‑treatment condition, request the mill test report and confirm lead time and payment details directly with the supplier.

Sourcing Chinese Competitive Steel 4140 from Dongguan Songshun Mould Steel Co., Ltd. - China Import Guide
Before placing an order, verify that the steel batch matches the chemical composition and mechanical properties stated in the mill test report. Confirm that the product complies with the specific standard required for your project, and ask for any additional certifications that may be needed for export to your country. Check the packaging method - typically bundled steel packs on pallets - to ensure it meets your handling and storage requirements.
Logistics should be clarified early: the supplier mentions FOB or CIF terms, so discuss the preferred incoterm, the loading port in China and the expected lead time for production and shipment. Payment terms are not disclosed in the listing, so negotiate a suitable arrangement such as a letter of credit or advance payment after a satisfactory sample is received. Align the shipping schedule with your production timeline to avoid delays.
Quality assurance is best supported by arranging a third‑party inspection before loading, focusing on dimensions, surface condition and heat‑treatment verification. Request a pre‑shipment sample if possible, and ensure that the supplier provides a certificate of conformity together with the commercial invoice and packing list. Proper documentation will facilitate customs clearance and reduce the risk of non‑conforming material entering your supply chain.
