Hot Rolled Alloy Steel Bar 4140
Dongguan Songshun Mould Steel Co., Ltd. supplies a hot rolled AISI 4140 chrome‑molybdenum alloy steel bar made in China. The alloy contains 0.80‑1.10 % chromium, 0.15‑0.25 % molybdenum and 0.38‑0.43 % carbon as specified by the supplier. Bar diameters are available from 20 mm up to 600 mm, with lengths up to 6 000 mm, a maximum plate thickness of 800 mm and a width capability of 2 200 mm. All dimensions follow the standard hot‑rolling tolerances indicated in the catalogue.
AISI 4140 is renowned for its combination of high tensile strength, good toughness and reliable machinability after heat treatment. Typical quenched‑and‑tempered 4140 bars achieve tensile strengths around 655 MPa and Rockwell C hardness between 28 and 32 HRC. The grade is widely accepted in automotive, machinery and oil‑field components where fatigue resistance is critical. Industry practice calls for ISO‑based quality management, which the supplier notes for this product.
Typical buyers include OEMs in the automotive, aerospace and construction sectors that require shafts, gears or structural members. The supplier states that minimum order quantities are flexible to accommodate both small‑batch and bulk projects. Products are shipped under FOB or CIF terms and are packaged in secure steel‑coil bundles to prevent damage during transit. Prospective importers should request the latest ISO certification and any heat‑treatment test reports before confirming the order.

Sourcing Hot Rolled Alloy Steel Bar 4140 from Dongguan Songshun Mould Steel Co., Ltd. - China Import Guide
Before placing an order, importers should verify the alloy’s chemical composition against the AISI 4140 standard, request the latest mill test report, and confirm that the supplied dimensions fall within the stated 20‑600 mm diameter and 6 000 mm length tolerances. Checking the ISO certification and any heat‑treatment certificates will also reduce the risk of non‑conforming material. A visual inspection of the coil or bundled pack for surface defects is advisable upon arrival.
The supplier offers FOB and CIF shipping from the port of Guangzhou, but exact lead times are not disclosed in the listing; buyers should ask for a production schedule and estimated sailing date. Confirm the preferred Incoterm, payment method - typically T/T against documents or a letter of credit - and any required advance deposit. Clarify whether freight forwarder services are arranged by the supplier or the buyer and whether insurance is included.
Independent third‑party inspection before loading is recommended to validate dimensions, hardness and surface condition against the agreed specifications. Request a certificate of compliance, test reports for tensile strength and hardness, and a packing list that details coil length and weight. Upon receipt, perform a sampling check and retain the documentation for customs clearance and future quality audits.
