A514 Gr B high strength steel plate surface cracks refer to the linear cracks on the surface of A514 Gr B high strength steel plate, which should generally be the same as the forging or rolling direction. Formation reason: it is mainly due to the hairline, hot crack and cold crack caused by surface over burning, decarburization, looseness, deformation and excessive internal stress during processing (forging, rolling, heat treatment, quenching and tempering), as well as the high content of sulfur and phosphorus impurities on the surface. Inspection method: A514 Gr B high strength steel plate surface cracks can be detected by naked eye observation, acid pickling, magnetic particle inspection, coloring inspection and metallographic method.
What are the characteristics of medium and thick plate, A514 Gr B high strength steel plate? First, the performance of shock resistance and vibration is very good, so the application of medium and thick plates in buildings and bridges can greatly improve the safety. Second, the bearing capacity of medium and thick plate, A514 Gr B high strength steel plate is good, the performance is excellent. The bridge, the automobile girder steel plate, and buildings have strict load-bearing requirements, and it is easy to cause accidents if the steel materials not meet the requirements, so the selection of steel is more stringent.
Expect in the A514 Gr B high strength steel plate goods regardless quality be still on the price after-sales service we all will keep in the middle of go together of advantage position real attain the ream customer satisfaction.Our advantage is: experienced craftsmen A514 Gr B high strength steel plate product development technology, excellent production team, hand strict quality control, sales and after-sales service.
