Characteristics of SA299 GrA pressure vessel steel plate

Characteristics of SA299 GrA pressure vessel steel plate:
SA299 GrA pressure vessel steel plate has low content of P, S and other harmful impurities. In the thickness direction of the steel plate, the chemical composition is uniform and there is no obvious component segregation.

SA299 GrA steel plate is a C-Mn SI steel used for boiler and pressure vessel plates in ASME standards. It is generally used for various weldments with working temperature not exceeding 400 °C, such as boiler drums and pressure vessels. It is required that SA299 GrA steel has high medium temperature strength, good plasticity, heat treatment process performance and welding process performance.
