The 5140 steel bar is a medium-carbon chromium alloy steel, equivalent to GB 40Cr and AISI 5140, supplied by Dongguan Songshun Mould Steel Co., Ltd. from China. This grade contains approximately 0.37-0.44% carbon and 0.70-1.10% chromium, giving it a balanced combination of strength, toughness, and wear resistance after heat treatment. The bars are available in diameters from 20mm to 800mm and in lengths of 3000mm to 5800mm, with hot-rolled or forged surface finish options to suit different downstream processes.
In production, 5140/40Cr steel is typically quenched and tempered to achieve tensile strengths in the range of 750-1000 MPa depending on section size and treatment condition. The chromium addition improves hardenability compared to plain carbon grades, allowing more uniform mechanical properties across larger cross-sections. Standard delivery condition is usually hot-rolled and annealed, though normalised or quenched-and-tempered states can be arranged. The material conforms to GB/T 3077 for alloy structural steels, with equivalent references to ASTM A29 and JIS G4104 for international buyers.
This steel finds its primary market in automotive transmission components, heavy machinery shafts, gears, axles, and high-strength fasteners where fatigue resistance under cyclic loading is critical. Importers typically procure in full-length bars for subsequent machining or forging operations. When dealing with Dongguan Songshun Mould Steel Co., Ltd., buyers should confirm exact diameter tolerances, length cutting charges, and any required ultrasonic testing or certification before finalising orders.

Before placing an order with Dongguan Songshun Mould Steel Co., Ltd., verify the supplier's current operational status and communication responsiveness, given the recorded zero response rate. Request a current mill test certificate from recent production to validate material specification compliance. Confirm that the 5140/40Cr designation matches your national standard equivalence requirements, and specify any additional testing such as ultrasonic inspection or hardness verification that your application demands.
For logistics, clarify whether delivery is ex-works from the Dongguan address or includes delivery to a specified export port such as Shenzhen or Guangzhou. Common Incoterms for Chinese steel exports are FOB Shenzhen or CIF destination port. Payment terms typical for first transactions with Chinese steel suppliers involve 30% advance with 70% against copy of bill of lading, though terms vary with relationship length and order volume. Letter of credit arrangements may be possible for larger values.
Upon arrival, inspect bundles for correct marking, count, and visible surface condition. Cross-check mill certificates against order specifications for chemical composition and mechanical properties. For critical applications, arrange independent laboratory testing of samples for tensile strength, hardness, and chemical verification. Retain all documentation for customs clearance and any subsequent quality claims, noting that Chinese export steel may require specific import licences or anti-dumping duty checks in certain destination markets.
