Available Grades — A516 Grade 55 / 60 / 65 / 70 Steel Plate

1. ASTM A516 Grade 55 Steel Plate

A516 Grade 55 steel plate is typically selected for lower-pressure vessels and boilers where moderate strength requirements apply. It offers good weldability and cost efficiency for standard pressure applications.

2. ASTM A516 Grade 60 Steel Plate

A516 Grade 60 steel plate provides improved tensile strength and notch toughness compared with Grade 55. It is commonly specified for medium-pressure vessels, storage tanks, and heat exchangers where moderate-to-high performance is required.

3. ASTM A516 Grade 65 Steel Plate

A516 Grade 65 steel plate is used when higher strength is required without significantly increasing plate thickness. It is commonly specified for larger vessel shells and pressure-retaining components.

4. ASTM A516 Grade 70 Steel Plate

A516 Grade 70 steel plate is the most widely used grade for pressure vessels and boilers. It offers higher strength, good notch toughness, and stable welding performance. For thicker plates or low-temperature service, A516 Grade 70 normalized plate (A516 Grade 70N) is often specified.

Delivery Condition — As-Rolled vs Normalized A516 Steel Plate

ASTM A516 steel plates can be supplied in different delivery conditions depending on project requirements:

• As-Rolled A516 Steel Plate
  Suitable for standard pressure vessel fabrication with shorter production lead times.
• Normalized A516 Steel Plate (Including A516 Grade 70N)
  Provides improved toughness and a more uniform microstructure. Normalized plates are recommended for thicker sections, low-temperature service, or when Charpy V-notch impact testing is specified by design codes.

Typical Applications of ASTM A516 Steel Plate

ASTM A516 steel plates se utilizan ampliamente en:

• Industrial boilers & steam drums
• Petrochemical pressure vessels
• LPG & LNG storage tanks
• Heat exchangers and condenser units
• Power generation equipment
• Pressure tanks and separators

A516 Grado 70 remains the most used grade for high-pressure welded structures, but many fabricators also choose Grado 60 o Grado 65 depending on the design requirements.

Carbon steel plates used for pressure vessels are often sourced together with structural grades depending on the project scope. Buyers who require multiple specifications for boilers, storage tanks, or fabrication projects may also review our complete carbon steel plate supply range to compare structural and PVQ plates available for export.

FAQ — ASTM A516 / ASME SA516 Steel Plate

• Is SA516 the same as ASTM A516?
  Sí. SA516 is the ASME version of ASTM A516, and both refer to the same material used in pressure vessels and boilers. The primary difference is that SA516 is typically used for the ASME code requirements, while ASTM A516 is for more general applications.
• What is the most commonly used grade?
  ASTM A516 Grado 70 is the most widely applied grade due to its balance of strength, toughnessy excelente soldabilidad. It is commonly used for high-pressure applications in boilers, pressure vesselsy depósitos de almacenamiento. For low-temperature applications, ASTM A516 Grade 70N is often specified.
• What thickness range can you supply for ASTM A516 steel plates?
  Suministramos ASTM A516 steel plates with thicknesses ranging from 6 mm to 150 mmcon custom cut-to-length services available. Whether you need standard or specialized thicknesses, we can meet your project requirements.
• Do you supply ASTM A516 steel plates with mill test certificates?
  Yes, all ASTM A516 steel plates are provided with EN 10204 3.1 mill test certificates, ensuring full material traceability and compliance with your specifications. This ensures the material’s compliance with international standards.
• When should I choose normalized material?
  Normalized ASTM A516 steel plates are recommended for thicker plates, low-temperature service, or when Charpy impact testing is specified by design codes. A516 Grade 70N is particularly useful for improving toughness in applications requiring high performance at lower temperatures.
• What is A516 Grade 70N?
  ASTM A516 Grade 70N es un normalized version de Grado 70 steel plate. It offers improved toughness y more uniform microstructure, making it ideal for thicker plates or applications that require rendimiento a bajas temperaturas o resistencia al impacto.
