GB713 Q245R Pressure Vessel And Boiler Steel Plate

GB713 Q245R is a Chinese standard (GB/T 713) grade of boiler and pressure vessel steel plate, which is a low-carbon steel with good mechanical properties, primarily used to manufacture pressure vessels, boilers, and storage tanks. The "R" in the grade indicates that it is specifically for pressure vessels, while the "245" denotes the minimum yield strength, which is approximately 245MPa.

Chemical Reaction Vessels

GB713 Q245R 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

GB713 Q245R 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

GB713 Q245R 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 GB713 Q245R 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 GB713 Q245R pressure vessel steel plate is commonly used.

What is the difference between Q345R and Q245R?

Difference Between Q345R and Q245R Steel Plate
For example: Obviously Q345R has the advantage on pressure vessel yield strength; while Q245R shows advantage on Calculation of container stiffness, and for Q245R is carbon steel, it has price advantage compared to low alloy steel-Q345R.

What is the ASME material equivalent to Q245R?

The equivalent ASTM material for Q245R, a Chinese low-alloy steel grade used for pressure vessels, is ASTM A516 Grade 60

What material is Q245R made of?

The Q245R plates are also corrosion-resistant and heat-resistant, making them appropriate for highly pressurized gases and steam. This alloy is made of low-carbon steel, which makes them robust.
