Hot rolled A387 grade 11 pressure vessel steel sheet heat treatment

What are the characteristics of medium and thick plate, A387 grade 11 pressure vessel steel sheet? 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, A387 grade 11 pressure vessel steel sheet 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.

If you have any requirements for the mode of transportation of the A387 grade 11 pressure vessel steel sheet goods, we can also negotiate and meet your requirements. For logistics, first of all, we respect customers' opinions, and then choose the most convenient port and transportation mode with appropriate price for customers.

Fine cutting of parts, when the A387 grade 11 pressure vessel steel sheet thickness of parts is not greater than 8mm, the verticality of the section can not be greater than 6% of the thickness of parts;When the thickness of the part is 8-14mm, the verticality of the section should not be greater than 8% of the A387 grade 11 pressure vessel steel sheet thickness of the part.

Hydrogen (H) is the most harmful element in general steel such as A387 grade 11 pressure vessel steel sheet. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.
