Chemical composition and mechanical properties of SA662 GrC boiler vessel plate

SA662 GrC boiler vessel plate is an American standard container plate, which implements the ASME standard. It belongs to the C-Mn steel plate for pressure vessels, and is mainly used for the manufacture of low-temperature welded pressure vessels. SA662 GrC boiler vessel plate is used in petroleum, chemical, power station, boiler and other industries, used to make reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear energy reactor pressure shells, boiler drums, liquefied petroleum cylinders, high pressure in hydropower stations water pipes, turbine volutes and other equipment and components.

SA662 GrC boiler vessel plate chemical composition:
C≤0.20, Si: 0.15-0.50, Mn: 1.00-1.60, P≤0.035, S≤0.040, Als ≥0.020

SA662 GrC boiler vessel plate production process:
Electric furnace smelting → LF/VD furnace refining → ingot casting → steel ingot cleaning → steel ingot heating → plate rolling → ultrasonic flaw detection → normalizing → finishing → inspection → storage
