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.

FAQ — ASTM A516 / ASME SA516

• Is SA516 the same as ASTM A516?
  Yes. SA516 is the ASME version, ASTM A516 is the ASTM version.
• What is the most commonly used grade?
  A516 Grado 70 is the most widely applied due to its strength and toughness.
• When should I choose normalized material?
  For thicker plates, low-temperature service, or when Charpy impact requirements are specified.
• What is A516 Grade 70N?
  A normalized version of A516 Grade 70. It provides better toughness and is recommended when Charpy impact requirements are specified.
