GL-E32 TM open barge steel plate surface cracks refer to the linear cracks on the surface of GL-E32 TM open barge 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: GL-E32 TM open barge steel plate surface cracks can be detected by naked eye observation, acid pickling, magnetic particle inspection, coloring inspection and metallographic method.
Cold rolled coil products GL-E32 TM open barge steel plate have accurate size and uniform thickness, and the thickness difference of coil is generally less than 0.01-0.03mm or less, which can fully meet the requirements of high precision tolerance. The surface quality of cold rolled products GL-E32 TM open barge steel plate is superior, and there are no defects such as pockmarks, pressing iron oxide scale and so on, which often appear in hot rolled coils. According to the requirements of users, coils GL-E32 TM open barge steel plate with different surface roughness can be produced (glossy surface or matte surface, etc.).
The amount of Vanadium in steel material is generally between 0.04% and 0.12%. The role of Vanadium is to affect the microstructure and properties of steel material. It mainly precipitates in the ferrite at the austenite grain boundary, and can inhibit the recrystallization of austenite and prevent the crystal during rolling. The grains grow, which refines the ferrite grains and improves the strength and toughness of GL-E32 TM open barge steel plate etc. steel material.
