SA302 Grade B for liquefied gas tank

<b>1.What is SA302 Grade B?<!–b>

• Type: SA302 Grade B is a manganese-molybdenum alloy steel plate for American standard pressure vessels (some also consider it as a manganese-molybdenum-nickel alloy steel plate).
• Grade Interpretation:

• • “SA” represents the American standard vessel plate.
  • “302” indicates the approximate value of the minimum yield strength of the steel plate (unit: MPa, but it should be noted that this number is not an exact value but used for grade identification).
  • “Gr” is likely the abbreviation of “Grade” (grade), and “B” represents the quality grade of the steel plate.

<b>3.In which industries is SA302 Grade B steel plate widely applied, and what equipment is it used to manufacture?<!–b>

• Petroleum and Chemical Industry: Used to manufacture key equipment such as reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, and liquefied gas tanks. These equipment often need to withstand high temperatures, high pressures, and the erosion of corrosive media.
• Power Stations and Boilers: Used to manufacture components such as boiler shells, furnace 胆 (furnace linings), flue ducts, and pressure shells of nuclear reactors in nuclear power plants. Its good high-temperature resistance and strength enable it to maintain stable performance in high-temperature and high-pressure environments.
• Hydropower Stations: Used to manufacture hydraulic equipment such as high-pressure water pipes and turbine scrolls.
• Other Fields: Also applied to heavy equipment such as bridges, offshore platforms, and ship structural components. Its high strength and good welding performance enable it to play an important role in various complex environments.
