Import A53 Carbon Steel Round Bar — Buy in Bulk from Supplier in Viet Nam

Shandong Jintuo Metal Materials offers A53 carbon steel round bar manufactured to ASTM A53 specification, with thickness range from 0.1 mm to 300 mm or as required. The A53 grade is an American standard carbon steel suitable for applications requiring low stress and high toughness, including structural components, pipe blanks, and general engineering. Available processing includes hot rolling, forging, and cold drawing, with surface treatment options of clean, blasting, or painting per customer requirement. The supplier reports annual capacity of 250,000 tons.

Hot rolled round bar in this grade typically exhibits ferritic-pearlitic microstructure with moderate strength and excellent weldability. The source indicates suitability for cold rolling, cold punching, cold heading, cold bending, and hot rolling processes, plus carburizing and carbonitriding for case-hardened applications. Typical mechanical properties for A53 Grade B include minimum yield strength of 240 MPa and tensile strength of 415 MPa, though buyers should request actual test certificates. Thickness tolerance is stated as plus or minus 0.1 mm, which is tight for hot rolled product and should be verified for specific diameter ranges.

Primary applications include car body construction, container fabrication, deep stamping vessels, pipes, gaskets, seamless steel pipe blanks, and building structural elements. The material also serves for manufacturing machinery parts, transmission shafts, and chassis components where weight reduction through optimized design is sought. Buyers should confirm exact diameter availability, length options, and whether cutting to size is provided. Export packing uses waterproof paper and steel strip in standard seaworthy packaging suitable for all transport modes.

Shandong Jintuo Metal Materials Co., Ltd operates from Viet Nam as an imported-tier supplier with harbor trust classification. The company name references Shandong Province in China, but the listed origin country is Viet Nam, suggesting either a Vietnamese operating entity with Chinese parentage or a relocated/established facility. No specific address, year of establishment, employee count, or revenue figures appear in the source data. Response rate is recorded at 0.00 percent with zero average response hours, indicating minimal platform engagement or inactive monitoring.

The supplier lists multiple international standards (AISI, ASTM, DIN, BS, JIS, GB, SUS, EN) suggesting broad market targeting, though buyers should verify which standards are actively certified rather than technically referenced. The stated annual capacity of 250,000 tons implies substantial mill or stockholding operations. No named clients, project references, or certification details (ISO, mill accreditation) are present in the source. Buyers should request company registration documents in Viet Nam, verify VAT/TIN numbers, and confirm whether the entity is a manufacturer, trader, or hybrid before advancing to sample orders.
