Products Description
The yield strength of ASTM A633 varies depending on its grade. ASTM A633 is a high-strength low-alloy steel commonly used in structural applications and is available in several grades (A, C, D, E), each with different mechanical properties. Below are the approximate yield strengths for the most common grades:
Grade A: 290 MPa (42 ksi)
Grade C: 345 MPa (50 ksi)
Grade D: 345 MPa (50 ksi)
Grade E: 415 MPa (60 ksi)
The exact yield strength might vary slightly depending on the manufacturer and specific application requirements. If you're using it in a design, confirm the exact value with the material's specification sheet or supplier.

Products Application
ASTM A633 steel plate is a high-strength structural steel known for its excellent toughness and weldability, making it ideal for equipment that operates under low temperature or high-pressure conditions. It is widely used in the petroleum, chemical, power generation, shipbuilding, and boiler manufacturing industries.
In the petroleum and chemical industry, A633 plates are commonly used in the manufacture of pressure-bearing components such as reactors, heat exchangers, separators, spherical storage tanks, and oil or gas pipelines. These components must endure high temperature, high pressure, and sometimes corrosive media.
In the power and energy sector, this steel plate is utilized for boiler drums, high-pressure water pipes, heat exchanger shells, turbines, and pressure vessels. Its excellent strength and impact resistance ensure long-term safety and reliability under steam or high-pressure environments.
Additionally, A633 plates are applied in nuclear and energy transportation systems, including nuclear reactor pressure shells, liquefied gas tanks, LPG cylinders, and oil & gas transport pipelines. The material's superior mechanical performance and fracture toughness make it suitable for extreme operating conditions.
