从China供应商批发进口A573gr.65 Carbon Steel Sheet — FOB条款

A573GR.65 is a normalized structural carbon steel plate governed by ASTM A573, with a minimum yield strength of 65 ksi (240 MPa) and tighter chemistry control than the lower grades in the same specification. Jiangsu Steel Group Co., Ltd. markets this grade within a broad portfolio that includes A573GR.58 and A573GR.70, offering plates from 8 mm to 600 mm thick, 1500 mm to 4200 mm wide, and 6000 mm to 18000 mm long. The material is supplied with clean, blast-cleaned, or customer-specified painted surfaces for welded construction and engineered structures.

Chemically, A573GR.65 limits carbon to 0.22 % maximum, manganese ranges 0.85-1.20 %, and silicon sits at 0.15-0.40 %, with phosphorus and sulfur each capped at 0.035 %. The normalized heat treatment produces a uniform ferrite-pearlite microstructure, yielding typical tensile strength of 450-530 MPa and minimum 20 % elongation in 200 mm gauge length. Bridge engineers and heavy-fabrication contractors select this grade when design stresses exceed the capacity of A36 or A573GR.58, but fall short of requiring quenched-and-tempered plate.

Primary applications span highway and railway bridge girders, transmission tower bases, heavy crane runway beams, and large welded pressure-containing structures where moderate notch toughness is adequate. The supplier indicates trade terms of FOB, CFR and CIF, with settlement by T/T or letter of credit at sight. Importers should lock in dimensional tolerances to ASTM A6/A6M, agree on mill certificate content, and clarify whether normalizing is included or priced separately before contract execution.

Jiangsu Steel Group Co., Ltd. is headquartered at 10/f, No. 257 Siping Road, Hongkou District, Shanghai 200080, China, operating as an imported-tier supplier with harbor-level trust verification on the platform. The profile shows no response activity, with a 0.00 % response rate and zero average response hours, which means buyers should anticipate delays or rely on direct contact outside the platform messaging system. No manufacturing plant addresses, warehouse locations, or production equipment harbor any mention in the disclosed data.

The company's listed scope covers carbon steel coils and sheets across ASTM, JIS, GB and DIN grades, implying either trading house or mill-consolidator operations rather than single-product mill direct sales. Absent from the profile are ISO certifications, specific mill partnerships, annual tonnage figures, employee counts, revenue data, named reference customers, and quality-system audit results. Prospective buyers must conduct independent supplier verification, including mill traceability checks and on-site or third-party facility audits, before committing to volume orders.
