High-Quality Carbon Steel Plates for Pressure Vessels and Boilers

Product Overview — ASTM A516 Steel Plate for Boilers & Pressure Vessels

ASTM A516 Steel Plate is a carbon steel plate specially designed for service in welded pressure vessels where improved notch toughness is critical. Supplied in grades A516 Grade 55, A516 Grade 60, A516 Grade 65, and A516 Grade 70, this material is widely used in boiler fabrication, storage tanks, heat exchangers, and industrial pressure vessel steel plate applications.

For projects requiring higher strength and improved toughness, A516 Grade 70 steel plate is the most commonly selected option. CJM supplies A516 Grade 70 steel plates with competitive pricing, fast delivery, and full material traceability for all grades.

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

• ASTM A516 Grade 55 Steel Plate
• ASTM A516 Grade 60 Steel Plate
• ASTM A516 Grade 65 Steel Plate
• ASTM A516 Grade 70 Steel Plate

Plates can be supplied in as-rolled, normalized, or stress-relieved condition upon request. For projects requiring higher notch toughness or low-temperature reliability, A516 Grade 70 normalized plate (A516 Grade 70N) is often preferred.

A516 Steel Plate Typical Applications

A516 steel plate is widely used in:

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

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

Normalized vs As-Rolled — A516 Steel Plate Options

Both delivery conditions are available:

As-Rolled A516 Steel Plate

• Suitable for standard boiler and vessel fabrication
• Shorter production time

Normalized A516 Steel Plate (Including A516 Grade 70N)

• Improved toughness
• More uniform microstructure
• Recommended for low-temperature service, thick plates, or pressure-critical equipment

Many EPC contractors specify Charpy V-Notch impact testing for normalized plates.

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 Grade 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.
