Q355GNH weathering steel is a kind of atmospheric corrosion resistant steel, which has better corrosion resistance than 05CUPCRNI usage, ordinary carbon steel by adding less alloy elements. Q355GNH weathering steel has been widely used in container, railway vehicle, bridge, building and air preheater which need to be resistant to atmospheric corrosion. Q355GNH weathering steel is characterized by the addition of less Cu, P, Cr, Ni and other alloy elements in the steel, so that a dense amorphous spinel type oxide layer with a thickness of about 50-100μm is formed between the rust layer and the base metal, which can prevent oxygen and water from penetrating into the steel matrix, slow down the development of corrosion to steel materials, and improve the atmospheric corrosion resistance.
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 05CUPCRNI usage, 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 company has new project in Peru. It is about more than 2000 tons 05CUPCRNI usage, LSAW steel pipes and large diameter pipe fittings, an repeat order for Peru Goverment. The fittings include Manhole, big Elbow, Bifurcation, etc. Since 2012 when we cooperated with the Peru Goverment to operate the hydropower project, they have repeat orders for us almost every year.
The Indian iron and 05CUPCRNI usage 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 05CUPCRNI usage decline was 7.7%, about 8 million tons. " Isa said.
