SA662 Grade A for chemical industry

SA662GrA steel plate is an American standard pressure vessel plate, mainly used for medium and low temperature pressure vessels.

It belongs to carbon-manganese-silicon steel plate, a killed steel, with excellent properties such as high strength, high toughness, fatigue resistance, impact resistance and wear resistance.

In SA662GrA, “SA” represents the American standard pressure vessel plate, “662” indicates that the minimum yield strength of the steel plate is 622MPa, “Gr” is the abbreviation of “grade” representing the quality grade, and “A” means the impact temperature is 40℃.

Dimensional Specifications :Thickness: 6MM to 300MM Width: 1500mm to 4050mm Length: 3000mm to 15000mm

1.What are the chemical composition and mechanical property of SA662 Grade A for chemical industry?

2.What are the performance advantages of SA662 Grade A for pressure vessel?

• Yield strength: The minimum value is generally 622 MPa (however, it should be noted that the actual yield strength may vary depending on the product, and specific values should refer to the product manual or relevant standards).
• Tensile strength: Ranges between 400 and 500 MPa, ensuring the stability of the steel plate during stretching.
• Elongation: When the gauge length is 200 mm, the elongation shall be greater than or equal to 20%; when the gauge length is 50 mm, the elongation shall be greater than or equal to 23%. These indicators demonstrate the good plasticity and ductility of the steel plate.

3.What are the typical applications of SA662 Grade A?

SA662GrA is widely used in industries such as petroleum, chemical, power stations, and boilers, and is used to manufacture equipment and components such as reactors, heat exchangers, separators, spherical tanks, oil-gas tanks, liquefied gas tanks, nuclear reactor pressure vessels, boiler drums, liquefied petroleum gas cylinders, high-pressure water pipes for hydropower stations, and turbine scrolls.
