Straightening technology of EN steel grade S355NL material

Ultrasonic flaw detection emits ultrasonic waves to the EN steel grade S355NL material 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 EN steel grade S355NL material steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.

Q345R steel (16MnR) is a low-alloy high-strength steel. It is a special plate for pressure vessels with a yield strength of 340MPa min. Q345R plate has good comprehensive mechanical properties and technological properties. The phosphorus and sulfur contents are slightly lower than the low-alloy high-strength steel plate Q345 steel (16MnR). In addition to the increased tensile strength and elongation requirements compared to Q345B steel, EN steel grade S355NL material, the impact toughness is also required.
