Import A106gr. B Carbon Steel Round Bar — Buy in Bulk from Supplier in Viet Nam

Shandong Jintuo Metal Materials Co., Ltd offers A106 Grade B carbon steel round bar from their Viet Nam operation, with stated tensile strength of 415 MPa characteristic of this grade. The product is available in diameters from 13.7 mm to 711.2 mm (approximately 1/4 inch to 28 inches), and in thickness or length dimensions from 0.1 mm to 300 mm according to customer requirement. The steel is produced by hot rolling, forging, or cold drawing processes, with surface treatment options including cleaning, blasting and painting to customer specification.

A106 Grade B is a low-carbon steel with carbon content typically below 0.30%, balanced with manganese for strength and silicon for deoxidation. The grade is formulated for high-temperature service, exhibiting adequate creep strength and oxidation resistance for boiler and pressure vessel applications. Hot-rolled round bar in this grade typically shows a ferritic-pearlitic microstructure with grain size conforming to ASTM E112. Cold-drawn product offers closer dimensional tolerances and improved surface finish but requires stress-relief annealing to restore ductility for subsequent machining or forming operations.

The primary applications include automotive structural components such as girders, beams, transmission shafts and chassis parts where weight reduction through optimized design is sought. The material also serves as billet stock for seamless pipe production and general engineering applications. The supplier cites annual capacity of 250,000 tons, though buyers should verify current allocation and scheduling. Standard export packing employs waterproof paper and steel strapping; Incoterms, exact lead time, and payment structures are not specified and require direct confirmation with Shandong Jintuo Metal Materials Co., Ltd.

Shandong Jintuo Metal Materials Co., Ltd operates as an imported-tier supplier with harbor trust classification. The company sources or processes carbon steel products from Viet Nam, though the exact legal entity structure, facility location within Viet Nam, and operational history are not detailed in the available data. The response rate and average response time are both recorded at zero, indicating no platform-mediated communication history. Buyers should establish direct email or telephone contact to evaluate sales engineering capability and language support.

The supplier profile does not disclose ISO certification status, export license details, banking references, or major client installations. No information is provided regarding in-house testing capabilities, third-party inspection relationships, or membership in industry associations. The stated 250,000 ton annual capacity figure is unverified and should be treated as a marketing claim until supported by production records or audit documentation. Importers are strongly advised to conduct supplier due diligence including factory visit or video inspection before significant financial commitment.
