ASTM A612 High-Strength PVQ Steel Plate

A612 steel plate is the standard specification for pressure vessel plates that are high strength, carbon steel for moderate and lower temperature use.

Overview:

  • High-strength pressure vessel quality steel plate for use in moderate and low temperatures.
  • Maximum thickness supplied is 1 inch.
  • Due to quickly shifting inventory with this grade of structural steel, please inquire about available sizes.

 

Minimum order weight in the USA is 20 tons. For orders weighing less than 20 tons, additional freight surcharges may be applied. Minimum order weight for orders outside of North America is 500 MT.
