The P355NH, P355NL1 and P355NL2 boiler steel plates are fine‑grain normalized alloy steels offered by Henan HZZ Iron and Steel Co., Ltd. They are manufactured to EN 10028‑3 and supplied in thicknesses from 5 mm to 200 mm, with widths up to 3800 mm and lengths up to 18000 mm to suit large‑scale pressure vessel projects. The normalized heat‑treatment provides a uniform microstructure that improves low‑temperature toughness, essential for storage tanks and reactors operating in harsh environments. The supplier lists the plates under the P355N family, indicating suitability for high‑pressure boiler and pressure equipment applications.
Typical chemical composition includes carbon up to 0.22 %, manganese up to 1.5 % and nickel up to 0.30 %, delivering a balance of strength and ductility. Mechanical properties commonly meet a minimum yield strength of 355 MPa and a tensile strength range of 485‑620 MPa, with Charpy impact energy of at least 27 J at - 20 °C. The product can be supplied with a range of heat‑treatment options such as annealing, TMCP, normalising or quenching‑tempering, depending on the buyer’s specification. Standard testing services include ultrasonic testing, Charpy V‑Notch impact, hydrogen induced cracking (HIC) testing, non‑destructive testing and optional coating or painting.
Major users include EPC contractors for oil‑ and gas storage tanks, steam generators and heat exchangers in the energy sector. Buyers typically request mill test certificates, compliance with ISO or CE, and may negotiate FOB, CIF, CFR or CNF terms. The plates are usually packed in steel‑coiled bundles or on pallets, with optional shot‑blasting or protective coating to prevent corrosion during transport. Importers should verify the exact dimensions, heat‑treatment state and any surface‑finish requirements before finalising the contract.

Before placing an order, buyers should confirm the exact grade (P355NH, P355NL1 or P355NL2) and verify that the mill test certificate aligns with EN 10028‑3 requirements. Request a detailed chemical analysis and mechanical test report for the chosen thickness, width and length. It is also prudent to ask whether any post‑process heat‑treatment or surface‑coating has been applied as part of the supply package.
Logistics arrangements should be clarified early, including the preferred Incoterm - common choices are FOB, CIF, CFR or CNF depending on the destination. The supplier indicates a typical production and delivery window of ten to thirty days after receipt of a confirmed purchase order and payment. Accepted payment methods are telegraphic transfer (T/T) or letter of credit (L/C), and buyers should specify packaging such as steel‑coil bundles or palletised sheets to ensure safe handling during transit.
Quality assurance can be reinforced by requesting third‑party inspection, for example SGS or an equivalent body, before loading. Inspection should cover dimensional accuracy, surface condition and verification of the HIC and impact test results. Upon successful inspection, the supplier will provide the full set of documentation, including the mill test certificate, packing list and certificate of origin, to satisfy customs and end‑user requirements.
