A514 grade B QT steel plate,S355J2 is a low-alloy high-strength steel, which can be treated to meet the requirements of Z-15, Z-25, Z-35 and level I, level II and level III flaw detection.The extension grades of S355J2 are S355J2, S355J2-Z35 and S355J2 + N-Z35, . On the basis of S355J2, S355J2-Z35 increases the requirement of S355J2 steel plate thickness direction performance, namely Z-direction performance. S355J2 + N-Z35 is a heat treatment process which increases Z-direction properties and normalizing rolling (or normalizing).A514 grade B QT steel plate

X-rays or γ-rays are projected on the surface of the steel plate, and rubber can be placed on the other side of the steel plate. Since the radiation propagates through the steel plate and is absorbed, the intensity is different due to the presence or absence of defects, so the film can record the shape and position of the defects. This method is sensitive to the detection of common steel plate defects such as slag inclusions, porosity and pores. The disadvantage is that it is difficult to find the specific depth of the defect and it is not easy to find cracks.
The tensile strength of A36 steel plate is 58-80 Ksi (about 400-550MPa), and the yield strength is 36 Ksi (about 250MPa); the tensile strength of Q235 steel plate is 370-500 MPa, and the yield strength is 235MPa; the tensile strength of SS400 steel plate is 400-510MPa, and the yield strength is 245MPa. For the mechanical properties of SS400 steel plate and Q235 steel plate, the thickness of steel plate is less than 16mm. It can be seen from the above data that ASME A36 and Chinese Q235 are named after the yield strength of the material, while SS400 is named after the tensile strength of the material.
