Rotability of low-carbon steel sheet, a variety of ship steel plate a36 low-carbon steel sheets with different metallographic properties and mechanical properties were subjected to deep-drawing spinning tests, from which the following points are directly related to the rotatable properties. The maximum elongation strain of aluminum killed steel plate of general purity exceeds 250% during deep drawing and spinning. The ultimate elongation of the boiling steel sheet with lower purity decreases with the increase of the oxygen content of the steel sheet.
The thickness of ship steel plate a36 is thicker than the general steel plate, and the accuracy is better. Otherwise, it will be broken by the impact of sea water during operation, which will bring life threatening to the people on the ship.
When the ship steel plate a36 thickness of the part is 14-20mm, the verticality of the section should not be greater than 12% of the thickness of the part.For their inspection mark, it is stipulated that: if the steel plate, section steel processing parts or stamping parts are inspected and qualified, the quality mark should be attached to prove that the inspection is qualified.
Myanmar's demand for ship steel plate a36 steel products is likely to exceed 3 million tons in 2020 and 5 million tons by 2025, according to seaisi. However, Myanmar's producers are unable to meet domestic demand, so the country's steel products are more dependent on imports. In 2019, Myanmar imported more than 1.9 million tons of ship steel plate a36 finished steel, including 57% of long products, 13% of uncoated hot-rolled and cold-rolled flat products, and 30% of coated steel. In order to reduce its dependence on imports, Myanmar plans to increase its steel production capacity by building and expanding steel mills.
