Import A573gr.58 Carbon Steel Sheet — Buy in wholesale FOB from Supplier in China

A573GR.58 is a normalized, structural-quality carbon-manganese-silicon steel plate under ASTM A573, with a minimum yield strength of 58 ksi (220 MPa), suited to moderate-duty welded construction and pressure vessel applications. Jiangsu Steel Group Co., Ltd. lists this grade alongside A283 and A36 variants, offering thicknesses from 8 mm to 600 mm, widths from 1500 mm to 4200 mm, and lengths from 6000 mm to 18000 mm. The mill supplies clean, blast-cleaned, or painted surfaces to customer specification.

The chemistry of A573GR.58 typically carries carbon up to 0.23 %, manganese 0.60-0.90 %, silicon 0.15ilen 0.40 %, phosphorus max 0.035 %, and sulfur max 0.040 %, with residual copper, nickel and chromium controlled for weldability. In standard practice the grade is supplied in the normalized condition, delivering a fine ferrite-pearlite microstructure that meets Charpy V-notch impact requirements at moderate temperatures. Typical mill certificates include tensile test results showing 400-490 MPa ultimate strength and 22 % minimum elongation in 200 mm.

Buyers in bridge fabrication, boiler manufacturing, high-pressure container construction and heavy structural engineering source A573GR.58 for its balance of strength, formability and cost against higher-grade alternatives. The supplier notes FOB, CFR and CIF terms, with payment by T/T or L/C at sight. Importers should confirm exact dimensional tolerances per ASTM A6/A6M, mill test certificate scope, and any third-party inspection requirements before finalising orders.

Jiangsu Steel Group Co., Ltd. maintains its registered address at 10/f, No. 257 Siping Road, Hongkou District, Shanghai 200080, China. The supplier is classified as an imported-tier vendor on the platform with a harbor trust tier, indicating basic profile verification without advanced badges. The response rate stands at 0.00 % with zero recorded average response hours, signalling that direct communication may be delayed or unmonitored through this channel.

The company lists carbon steel coils and sheets across multiple ASTM, JIS and EN grades, suggesting trading or mill-direct operations with breadth rather than single-grade specialisation. No fabrication facilities, warehouse locations, production capacities, employee counts, revenue figures, named clients, or certification holdings are stated in the available profile. Buyers should treat this as a steel supply intermediary and verify mill origin, quality-system accreditation (ISO 9001, mill-specific), and physical inspection access through direct due diligence.
