With the development of the society, disabled children gets increasing concerns and help from all walks of life. Fortunately, Chinese Government gives high concern to the handicapped children and has built Children Welfare Institutes all over the country to guarantee their lives.
The chemical composition of Q345D seamless steel pipe is as follows: C ≤ 0.18, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.030, S≤ 0.025, Nb ≤ 0.07, V ≤ 0.15, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.50, Cu ≤ 0.30, N ≤ 0.012, Mo ≤ 0.10, Al ≥ 0.015. A514 Gr E alloy steel plate, Q345D seamless steel pipe has good comprehensive mechanical properties, low temperature impact toughness, corrosion resistance, cold stamping, machinability and weldability. Q345D seamless steel pipe is widely used in welding structures, such as bridges, vehicles, ships, pipelines, boilers, large vessels, etc..
The deoxidation ability of Al is much stronger than that of Si and Mn when aluminum element (Al element) is added into steel as deoxidizer or alloying element. The main role of aluminum in A514 Gr E alloy steel plate etc. steel is to refine grain size and fix nitrogen in steel, so as to significantly improve the impact toughness of steel and reduce the tendency of cold brittleness and aging. Al element can also improve the corrosion resistance of steel, especially when used with molybdenum, copper, silicon, chromium and other elements. The wear resistance of chromium molybdenum steel and chromium steel can be increased by containing Al element.
In March, the daily output of key iron and steel enterprises decreased on a month on month basis. In terms of enterprise inventory, in late March, the key statistics showed that the A514 Gr E alloy steel plate steel inventory of iron and steel enterprises was 18.067 million tons, a decrease of 3.342 million tons or 15.6% compared with the highest inventory in early March, and an increase of 8.534 million tons or 89.5% compared with the beginning of the year.
Our company's business departments are a group of excellent and hard-working employees, who constantly carry out knowledge updating and steel knowledge training every day, only to provide better and professional services to customers.
Recently, the A514 Gr E alloy steel plate price has fallen into a dilemma, and Tangshan production restriction has started again. When the market transaction is weak, the A514 Gr E alloy steel plate price gain support again. Although the high demand is not good at present, which will restrain the rise of A514 Gr E alloy steel plate price, the preference of market mentality and cost side make most A514 Gr E alloy steel plate manufacturers optimistic about the prosperous season. Therefore, it is expected that the A514 Gr E alloy steel plate price will be easy to rise and difficult to fall in the near future, so it is suggested that businesses can make up stocks at low prices.
