We supply a full range of EN 10028-2 specified boiler and pressure vessel steel plates, including P355GH, 16Mo3, 10CrMo9-10, 12CrMo9-10, and 13CrMoV9-10. These hot-rolled plates are engineered for elevated temperature service, offering excellent creep resistance, high-temperature strength, and outstanding weldability. They are widely used in the fabrication of boilers, pressure vessels, heat exchangers, reactors, and piping systems in power generation, petrochemical, and nuclear industries.

High Purity Steelmaking: Low P, low S, and controlled gas content (H, O, N) via LF + VD/VOD refining.
Excellent High-Temperature Performance: Proven creep rupture strength and structural stability under long-term elevated temperature loading.
Superior Weldability: Low carbon equivalent design and controlled hardenability ensure good welding behavior with conventional processes (SMAW, SAW, GMAW, FCAW).
Accurate Dimension Control: Advanced rolling mills guarantee tight thickness, width, length, and flatness tolerances.
Z-Direction Property Available: For critical welded structures, plates can be supplied with through-thickness ductility (Z15 / Z25 / Z35 per EN 10164) upon request.
Full Traceability: Each plate is marked with heat number, plate number, grade, and standard; full mill test certificates (EN 10204 3.1 or 3.2) are issued.
