ASTM A573 Grade 65(A573 Gr 65) steel welding standards

Q345R steel plate is a special pressure vessel steel with a yield strength of 340 Mpa. ASTM A573 Grade 65(A573 Gr 65) steel, 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.

Ultrasonic flaw detection emits ultrasonic waves to the ASTM A573 Grade 65(A573 Gr 65) steel steel plate under inspection. If there are defects in the steel plate, the ultrasonic waves will reflect, refract or deform waveforms due to the defects. By recording these changes, the type and shape of the defects are analyzed. Due to its high energy and good penetration performance, and the smoothness of the ASTM A573 Grade 65(A573 Gr 65) steel steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.
