Import Alloy Steel Round Bar — Buy in Bulk from Supplier in China

Luli Group Co., Ltd. offers alloy steel round bars from their base in Shouguang, Shandong Province, a major steel-producing region in China. The bars are manufactured from premium alloy steel with mechanical properties suited to heavy-duty structural, automotive and manufacturing applications. The source indicates diameters and lengths are available across a range to suit project-specific requirements, though buyers should confirm exact stock dimensions directly. Weldability and machinability are stated features, indicating suitability for fabrication processes including welding, turning and milling operations. The alloy composition provides enhanced strength and corrosion resistance compared with plain carbon equivalents, a standard advantage of Cr-Mo and Ni-Cr alloy grades common in this product category.

Typical alloy steel grades for round bars include 4140 (AISI), 4340 and 8620, containing chromium, molybdenum, nickel and manganese in varying proportions to achieve specific mechanical properties. Standard bar diameters range from 6mm to 500mm, with hot-rolled delivery condition being typical for constructional applications and cold-drawn or peeled/ground finishes for precision engineering. Tolerance classes conform to ISO h9, h11 or k13 depending on finish, with straightness typically 1mm per metre for commercial grades and 0.5mm per metre for precision grades. Surface decarburisation limits are normally 0.3mm maximum for hot-rolled bars, critical for fatigue-sensitive applications. Heat treatment response, hardenability curves and Jominy test data are standard reference points when matching grade to application.

Primary buyers include manufacturers of shafts, gears, couplings, bolts and structural frameworks where tensile strength typically exceeds 700MPa in the quenched and tempered condition. The automotive sector uses these bars for axle components and steering linkages; oil and gas applications include drill collars and subsurface tools. Construction applications encompass high-strength bolting and reinforcing elements. Trade terms mentioned include FOB and CIF, with packaging arranged for safe transit. The response rate is recorded as 0.00 with zero average response hours, so buyers should expect delayed communication and plan enquiries accordingly. No minimum order quantity is specified in the source data.

Luli Group Co., Ltd. is headquartered in Houzhen, Shouguang, Shandong 262724, China, placing it within one of China's principal steel manufacturing corridors. The supplier tier is marked as 'imported' with a trust tier of 'harbor', indicating basic marketplace presence without advanced verification. The response rate is recorded at 0.00 with zero average response hours, which signals that prospective buyers should anticipate delayed or minimal communication and should factor this into their procurement planning. No information is provided regarding years in operation, facility scale, workforce size, annual revenue or specific client references.

The company listing promotes alloy steel round bars for construction, automotive and manufacturing applications, referencing ISO and SGS standards though no specific certificates are displayed. Buyers should independently verify any claimed certifications directly with the supplier rather than relying on source description alone. The address and regional concentration suggest production or distribution through Shandong's established steel network, but the listing does not confirm in-house melting, rolling or heat treatment capabilities. No details are given on export experience, banking references, or previous international shipments.
