SA285GrC Pressure Vessel Steel Plate

 

SA285GrC is a medium or low strength carbon steel plate for pressure vessels. It is a steel plate for boilers and is mainly used for the production of fixed boilers, hull boilers and other important boiler accessories.

 

The main differnence for these three carbon steel grades of SA285 Grade A, SA285 Grade B and SA285 Grade C is their yield strength and tensile strength. For pressure vessel steel plate SA285 Grade A,minimum yield strength shall be 165 Mpa and 24Ksi,and SA285 Grade B pressure vessel steel plate owned the minimum yield strength at 185 Mpa and 27 Ksi,then pressure vessel steel plate SA285 Grade C owned the highest yield among them,it shall be above 205 Mpa and 30 Ksi.So steel plate SA285 Grade C is the most common used in the industry.
