In terms of ship steel, according to industry experts, steel is mainly used in the construction of ship hulls, cargo holds, piping systems (including pumps and valves) and part of ship decoration. In addition to being used to build conventional ships, steel also plays an important role in the construction of various special ships such as LNG (liquefied natural gas) ships, large oil tankers, large container ships, and chemical tankers.
What are the characteristics of medium and thick plate, AH36 tensile strength? 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, ah36 tensile strength 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.
Hydrogen (H) is the most harmful element in general steel such as ah36 tensile strength. 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.
