S500Q steel equivalent chemical & mechanical composition

Q345R steel plate is a special pressure vessel steel with a yield strength of 340 Mpa. S500Q steel equivalent, Q345R pressure vessel steel has good comprehensive mechanical and technological properties. The content of phosphorus and sulfur of Q345R pressure vessel steel is slightly lower than that of Q345 (16Mn) steel, and the tensile strength and elongation requirements of Q345R pressure vessel steel are higher than those of Q345 (16Mn) steel, and the impact toughness of Q345R pressure vessel steel is also required. Q345R pressure vessel steel is the most widely used Chinese pressure vessel steel.

We do sand blasting and shop primer for various S500Q steel equivalent steel plates such as carbon steel plates, high strength low alloy steel plates, shipbuilding steel plates, etc. before delivery, so as to protect the steel plates from going rust during transportation. Our sand blasting standard is SA2.5, and shop primer S500Q steel equivalent thickness is 20μm or so. Our shop primer has been certified by ABS, LR, BV etc. authorities.
