What grade of steel is boiler plate?

Boiler plate, commonly known as boiler quality steel plate or pressure vessel quality (PVQ) steel plate, typically refers to a specific type of steel grade used for manufacturing boilers and pressure vessels. The grade of steel used for boiler plates is generally designated by specifications such as ASTM A516 Grade 70, ASTM A285 Grade C, EN 10028-2 P265GH, or similar standards that are specifically formulated for high-pressure and high-temperature applications.

One of the most common grades used for boiler plates is ASTM A516 Grade 70, known for its excellent notch toughness and weldability characteristics, making it suitable for various boiler and pressure vessel applications. These boiler plate grades are selected for their ability to withstand elevated temperatures and pressures while maintaining structural integrity and safety in demanding operating conditions.
