Import A204 Gr A,B,C Boiler Steel Plate — Buy in wholesale FOB from Supplier in China

Henan HZZ Iron and Steel Co., Ltd. supplies A204 Grade A, B, and C boiler steel plate, a molybdenum-alloy carbon steel conforming to ASTM A204 for pressure vessel and boiler fabrication. The material is produced in hot-rolled normalized or tempered condition, with standard thickness from 6mm to 150mm and widths reaching 2500mm. Grade differentiation follows ASTM A204 chemistry controls, where Grades B and C carry higher molybdenum and tensile requirements than Grade A. Mill test certificates accompany standard shipments, though buyers should verify the specific grade certificate matches their design code requirements before releasing payment.

The molybdenum addition, typically 0.45-0.58% depending on grade, provides marked improvement in creep resistance and elevated-temperature strength compared with plain carbon steels. Hot rolling followed by normalizing or tempering refines the ferritic-pearlitic microstructure, delivering the specified tensile strength of 75-95 ksi and yield strength of 40-47 ksi across the grade range. Weldability remains good with standard low-hydrogen processes, though preheat and interpass temperature controls apply for thicker sections. Standard surface condition is as-rolled with mill scale; shot-blasting or pickling can be requested for critical fabrication schedules.

Primary end-users are refinery contractors, power-plant EPCs, and chemical process licensors specifying ASME II Part A materials. The plates are bundled or palletized for ocean freight, with weight typically 20-25 metric tonnes per container load depending on thickness mix. Buyers should confirm whether Henan HZZ holds current ASME material organization approval, as this affects acceptability for U-stamped vessels. Incoterms, payment structure, and exact delivery schedule require direct negotiation, as the listing carries no confirmed trade terms.

Henan HZZ Iron and Steel Co., Ltd. is headquartered at Jincheng International Building in Zhengzhou, Henan Province, China, placing it within the Central China industrial corridor with access to mill-sourced plate from major domestic producers. The supplier is classified at imported tier with harbor trust level, indicating a registered entity without additional third-party verification badges on the platform. The response rate shows 0.00% with zero recorded average response hours, which signals that buyers should expect delayed or manual communication and should plan procurement timelines accordingly.

The listing profile does not disclose ASME material organization accreditation, ISO certification specifics, annual tonnage, or client references. Buyers must independently verify mill relationship, whether Henan HZZ trades as agent, stockist, or mill-direct exporter, and whether it can provide original mill test certificates with full chemical and mechanical traceability. The company website or direct inquiry is the necessary next step for due diligence on these points.
