Qilu Special Steel Co., Ltd produces forged round bars in Shandong, China. The product range includes grades GB/T 42CrMo, AISI 4140 and DIN 42CrMo4, all forged from premium alloy steel. Bars are supplied in lengths from 3000 mm to 6000 mm and diameters between 80 mm and 800 mm, matching the dimensions stated in the listing.
These alloy grades typically deliver tensile strengths around 950 MPa and a Brinell hardness of 260 HB, suitable for high‑load applications. Industry practice provides a surface roughness of Ra 1.6 µm and a diameter tolerance of ±0.3 mm. The hot‑forging process yields a uniform grain structure that improves fatigue resistance compared with cast equivalents.
The bars are commonly used in heavy‑duty machinery, automotive powertrain components and structural engineering projects. Qilu Special Steel can arrange FOB or CIF shipping from its Shandong plant and will confirm minimum order quantities, payment terms and delivery schedules upon inquiry. Buyers are advised to request the latest mill test report to verify chemical composition and mechanical properties. The supplier also offers the possibility of custom cutting to meet specific project lengths.

Prior to ordering, obtain the mill test report to confirm grade, chemical composition and mechanical properties, and ensure that the supplier’s harbor trust tier aligns with your risk assessment. Verify that the required diameter and length are within the supplier’s standard range or arrange a custom cut, and request any additional certifications needed for your market.
Clarify the preferred Incoterm - FOB or CIF - from the Shandong port, and discuss expected lead times based on the chosen length and any post‑forging heat‑treatment. Because the supplier’s response rate is recorded as zero, maintain regular follow‑up to lock in shipping dates and to finalise payment terms such as T/T or L/C.
Plan for an independent inspection either at the Qilu Special Steel facility or upon arrival to check dimensions, surface finish and hardness. Ensure that the shipment includes the mill test report, the ISO certificate and any other documentation required for customs clearance in your destination country.
