ASTM A203 Grade F Nickel-alloy Steel Plate

ASTM A203 Grade F is a nickel-alloy steel plate designed for welded pressure vessels operating at moderate or low temperatures. It has a nickel content of 2.25% to 2.75% and offers high strength and good low-temperature toughness, making it suitable for applications like LNG storage tanks and cryogenic plants.

Chemical Reaction Vessels

A203 Grade F Boiler and Pressure Vessel Steel Plate is used in synthesis reactions (such as ammonia synthesis towers in fertilizer plants and polymerization reactors in chemical plants). It needs to withstand high temperatures and pressures (e.g., the ammonia synthesis tower operates at a pressure of 30MPa and a temperature of 450℃) and medium corrosion (such as hydrogen and acid gases) to ensure no leakage or structural failure occurs during the reaction process.

Petrochemical Storage Tanks and Towers

A203 Grade F Low Temperature Pressure Vessel Steel Plate is used in storage tanks for crude oil, liquefied natural gas (LNG), and liquefied petroleum gas (LPG), as well as rectification towers and absorption towers in petroleum refining: normal temperature and pressure storage tanks (such as crude oil tanks); low-temperature storage tanks (such as LNG storage tanks, with temperatures as low as -162℃) require steel plates with excellent low-temperature toughness to avoid brittle fracture of steel at low temperatures; high-pressure hydrogenation towers (petrochemical hydrofining process).

Heat Exchange Vessels

A203 Grade F High-quality Boiler Steel Plate is used in equipment for medium heat exchange (such as shell-and-tube heat exchangers and plate heat exchangers). Their shells and tube sheets need to withstand alternating hot and cold shocks, ensure fatigue resistance, and avoid weld cracking caused by frequent temperature changes.

Metallurgical Industry

The "blast furnace hot blast stove" in steel plants (which stores high-temperature hot air, with a pressure of 0.5-1.5MPa and a temperature of 1200℃) uses high-temperature resistant A203 Grade F hot-rolled plate for its shell; the "autoclave" in non-ferrous metal smelting (such as the leaching autoclave in hydrometallurgical copper smelting) needs to be resistant to acid corrosion, and A203 Grade F pressure vessel steel plate is commonly used.
