It is not the thicker the steel plate is, the better. The larger steel plate thickness means higher price and purchase cost, and it is also not inconvenient for transportation. Besides, the thickness of GL-E32 TM open barge steel plate, steel plate has relation to the safety, so the thickness of steel plate is not determined at random, and the size data of steel plate should be strictly planned according to the requirements of drawings. Therefore, it is necessary to select the appropriate steel plate material and specification according to the use.
Phosphorus is a very harmful element in GL-E32 TM open barge steel plate steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of GL-E32 TM open barge steel plate steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.
According to the data released by the world iron and Steel Association, the world pig iron production in March 2020 was 103 million tons, a year-on-year decrease of 3.5%, a year-on-year increase of 1.8% in February, and the overseas pig iron GL-E32 TM open barge steel plate production excluding China was 36.309 million tons, a year-on-year decrease of 11%.
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.
