The Indian iron and normal strength RD hull steel plate Steel Association (ISA) lowered its steel demand forecast for 2020 to 5.1% from 5.1% in February this year. The figure is expected to hit a low of 7.7%. The company said in an official statement that the current share price has fallen sharply due to the huge downside risk. "We expect India's finished steel demand to fall to about 93.7 million tons by 2020, down from 101.5 million tons in 2019." This calendar year, the normal strength RD hull steel plate decline was 7.7%, about 8 million tons. " Isa said.
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 normal strength RD hull 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.
The main function of boron in normal strength RD hull steel plate and so on steel is to increase the hardenability of steel, so as to save other rare and precious metals, such as nickel, chromium and molybdenum. For this purpose, the boron content is generally regulated in the range of 0.001% - 0.005%. It can replace 1.6% nickel, 0.3% chromium or 0.2% molybdenum. It should be noted that molybdenum can prevent or reduce temper brittleness, while boron slightly promotes temper brittleness, so molybdenum can not be completely replaced by boron.
