The product is a hot‑rolled carbon steel plate supplied by Chongqing Perpetual Imp & Exp Co.,Ltd. It conforms to GB 713‑2014 under the designation Q345R, which is equivalent to ASTM Grade B. The plate’s chemical limits follow the standard, with carbon content allowed up to 0.22 % for thicknesses greater than 60 mm and optional trace additions of Nb, V, Ti not exceeding 0.05 %. The supplier notes that residual elements such as Cr, Ni, Cu must stay below 0.30 % and Mo below 0.08 %.
Q345R is a typical low‑alloy steel used for boiler and pressure‑vessel plates, offering a balance of strength and weldability. In the global market the plate is usually supplied in thicknesses from 6 mm to 80 mm, with width up to 2500 mm and length up to 6000 mm, matching standard mill rolls. Typical mechanical properties for this grade include a tensile strength of 470 - 630 MPa and a yield strength of 345 MPa, values that meet most shipbuilding specifications. The material’s carbon equivalent is often limited to 0.55 % to ensure good formability, a practice common across suppliers of Q345R.
Shipyards, energy‑infrastructure fabricators and heavy‑industry workshops are the main buyers of this plate for constructing hull sections, boiler shells and pressure‑vessel components. Importers should verify the mill test report, chemical analysis and dimensional tolerances before placing an order. Trade terms such as MOQ, Incoterms and payment schedule are not disclosed in the listing and must be confirmed directly with Chongqing Perpetual Imp & Exp Co.,Ltd.

Before confirming an order, verify that the mill test report lists the chemical composition, carbon equivalent and mechanical properties matching Q345R standards. Request a certificate of compliance with GB 713‑2014 and, if required, a third‑party inspection report. Confirm that any trace alloying elements are within the 0.05 % limit noted by the supplier.
Discuss the preferred Incoterm with Chongqing Perpetual Imp & Exp Co.,Ltd., as the listing does not specify it; common choices for Chinese exporters are FOB Chongqing or CIF a nearby port. Clarify the expected lead time once the order size and cutting requirements are finalised, and negotiate payment terms such as T/T or LC after reviewing the supplier’s response record. Because the response rate is currently shown as 0 %, establish a reliable communication channel before dispatch.
Arrange a pre‑shipment inspection by an accredited agency to verify thickness, surface condition and dimensional tolerances. Ensure that the supplier provides a signed mill test certificate and, if necessary, a heat‑treatment record. Maintaining these documentation checks reduces the risk of non‑conforming steel arriving at the fabrication yard.
