S355ML steel plates, Chinese material Q235B is one of the most widely used carbon steel in the world. Some like to compare its strength with other equivalent steel grades. We need to take care that the Q235B steel strength varies with thickness. For the min. yield strength of Q235B steel plate: it is 235Mpa if thickness ≤16mm, 225 Mpa for thickness 16-40mm, 215 Mpa for thickness 40-60mm, 205 Mpa for thickness 60-100mm, 195 Mpa for thickness 100-150mm, 185 Mpa for thickness over 150mm. The tensile strength of Q235B steel plate is 375-500 Mpa.

As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of S355ML steel plates steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.
