Special thick JIS SM520B plates supplier

Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of JIS SM520B plates circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and JIS SM520B plates management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.

EN10028-2 P235GH steel plate is a non-alloy quality steel with high temperature performance, executive standard: EN10028-2. Steel number: 1.0345. JIS SM520B plates, P235GH pressure vessel steel has good plasticity, toughness, cold bending performance and welding performance. The P235GH presure vessel plate and sheets size, shape and allowable deviation of the steel plate should meet the requirements of EN10028-1 2007 + A1: 2009.

The mechanical properties of 30CrMo steel are as follows: tensile strength 930 MPa, yield strength 785 MPa, elongation after fracture 12%, impact absorption energy 63 J. JIS SM520B plates, 30CrMo steel has high strength and toughness. When the temperature is lower than 500℃, 30CrMo steel has good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance. 30CrMo steel is generally used in quenched and tempered condition.

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 JIS SM520B plates 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 carbon content of JIS SM520B plates, medium carbon steel plate is 0.25% - 0.60%. In addition to carbon, it can also contain a small amount of manganese (0.70% - 1.20%). The medium carbon steel plate after quenching and tempering has good comprehensive mechanical properties. The highest hardness is about HRC55 (hb538) and σ B is 600-1100mpa.
