ASTM A387 Grade 12 Boiler Steel Plates

ASTM A387 Grade 12 pressure vessel plate vs A387 Grade 12 Class 2 Boiler Plates
ASTM A387 Grade 12 pressure vessel plate and A387 Grade 12 Class 2 Boiler Plates are utilized to hold and process fluids and gases. Both these modules can be distinguished from certain key features.

  • A387 gr 12 pressure vessel plate is designed to hold high pressured materials. They typically store compressed gas, oxygen, nitrogen, etc.
  • A387 Grade 12 Class 2 Boiler plates allow for combustion and heat transfer of water until it becomes hot water and steam, depending on the design of the module. The heating of water creates a tremendous force in the vessel.

What is ASTM A 387 GR. 12 CL. 1 / 2 Alloy Steel Plates?
ASTM A387 gr 12 class 1 and 2 modules are high-strength components in weldable steel pressure vessel systems. Both these grades have identical chemical compositions but can be distinguished based on their mechanical properties.

  • ASTM A387 Grade 12 Class 1 is designed with a tensile strength between 50ksi to 80ksi. The versatile grade has a yield strength of 33ksi and can be elongated by a minimum of 22%.
  • ASTM A387 Grade 12 Class 2 is produced with a tensile strength between 65ksi to 85ksi. The class exhibits a yield strength of 40ksi and can be easily elongated by 22%.

ASTM A387 Grade 12 Plate vs ASME SA387 Grade 12 Plate?
The grade 12 of A387 grade is designed by ASTM and ASME standards. Both these standards are nearly the same but can be distinguished based on certain characteristics.

  • ASTM A387 Grade 12 plate belongs to an organization that covers dimensions and codes for different technological services and industries. ASME SA 387 gr 12 plate covers a specification that covers a range of designs and specifications for a range of equipment utilized in the pressure vessel grades. 
  • ASTM grade covers nearly 12,000 or more standards for a range of services and products. ASME grade covers nearly 600 codes of different technical material.
