Introduction
Heat‑Resistant Steel Plate is a specialized alloyed flat‑rolled steel engineered to maintain strength, creep resistance, and oxidation protection in continuous service at elevated temperatures ranging from 500 °C up to 1,100 °C. Through precise additions of chromium, nickel, molybdenum, and silicon, coupled with controlled rolling and heat‑treatment, these plates deliver dependable performance in furnaces, boilers, and high‑temperature process equipment.

Features & Advantages
High‑Temperature Strength: Maintains mechanical properties and resists softening in prolonged service up to 1,100 °C.
Excellent Creep Resistance: Optimized alloy balance delivers long‑term stability under constant load at temperature.
Oxidation & Scaling Resistance: Alloying elements form protective oxide films, extending service life in oxidizing environments.
Good Weldability: Controlled carbon equivalent and stabilized grades permit reliable welding with minimal pre‑heat.
Dimensional Stability: Low thermal expansion and minimal distortion ensure tight tolerances under thermal cycling.
Applications
Furnace & Boiler Construction: Furnace walls, superheater and reheater panels, and furnace crowns.
Petrochemical & Power Plants: Heat‑exchanger tubesheets, header plates, and pressure vessel shells.
Industrial Kilns & Ovens: Lining plates, burner blocks, and door assemblies.
Steel & Glass Manufacturing: Holding chamber walls, trough liners, and glass melting tank components.
Incinerators & Combustion Chambers: Flame‑deflector plates and refractory backing supports.
Packaging & Delivery
Packaging:
Plates stacked with polymer or timber spacers; edges protected by galvanized steel angles.
Optional shot‑blast cleaning and high‑temperature corrosion‑inhibiting coating.
Wrapped in heavy‑gauge plastic or heat‑resistant paper; strapped for transport.
Lead Time: Standard production and shipment within 25–35 days after order confirmation; expedited schedules (15–20 days) available for urgent projects.
