ASTM A516 Grade 65 Steel Plate

ASTM A516 Grade 65 is an excellent weldable carbon steel choice for pressure vessels and boiler fabrication. The material offers excellent performance in lower than ambient temperature service, has good weldability and excellent notch toughness.

A516 Grade 65 has greater specified tensile and yield strength when compared with ASTM A516 Grade 60

Used throughout the oil, gas and petrochemical industry, the steel is also found in sour service and wet H2S applications (where the steel is HIC tested).

ASTM A516 Specifications

ASTM A516 is recommended for carbon steel plates for pressure vessels at moderate and lower temperature service.

The ASTM A516 specification is the Standard Specification for Pressure Vessel Plates, Carbon Steel, for Moderate- and Lower-Temperature Service for plates used in pressure vessel applications where excellent notch toughness is required. Four grades having minimum Tensile Strengths ranging of 55 ksi to 70 ksi are available.

ASTM A516/A516M-10(2015) standard specification covers carbon steel plates intended primarily for service in welded pressure vessels where improved notch toughness is important. According to different strength levels, the plates are available in four grades: Grades 55, 60, 65, and 70. The maximum thickness of plates is limited only by the capacity of the composition to meet the specified mechanical property requirements. The steel shall be killed and shall conform to fine austenitic grain size requirements. The mechanical properties such as tensile strength, yield strength, and elongation shall be determined by a tension test for the plates.

• Strength, Yield Strength ksi (MPa), Tensile Strength ksi (MPa): Strong, 70 (480)
  For higher strength and lower weight, consider Advanced High-strength Steels
• Formability: % Elongation: Basic, 20%
  For better formability consider Drawing Steel
• Joining – Fair
  Design and welding must account for stresses
• Corrosion Resistance – Good
  Galvanizing will slow corrosion.  For longer life in harsh chemical conditions, consider Galvanized or Coated Steel
• Chemistry – Medium carbon, medium manganese, with silicon
• Cost – Higher.
  Good when thinner or stronger steels will add value.

What is A516 Grade 60 steel?

ASTM A516 Grade 60 is a boiler and pressure vessel quality steel which is ideal for moderate and lower temperature service. The material is used extensively by industrial boiler and pressure vessel fabricators who provide manufacturing support to the oil, gas and petrochemical industry.

What is ASTM A516 Grade 70?

ASTM A516 Grade 70 is a boiler / pressure vessel quality of steel plate for use in low to moderate services. It has improved notch toughness. A516 GD70 steel plate is equivalent to the P355GH and 490B grades.
