Grade A ship steel is mainly used for the internal frame of the ship and the outer plate bearing general stress. Grade B, Grade D and Grade E ship steel DIN 17102 TStE285 steel hardness can be used for important structures in high stress areas such as hull outer plate and main deck. The Grade E ship steel has good low temperature performance, which is suitable for the hull outer plate, deck, etc. According to the minimum yield strength, the high-strength ship steel is divided into four grades: A, D, E and F. The commonly used high strength ship steels are AH32, DH32, EH32, etc.
For the DIN 17102 TStE285 steel hardness construction industry, the largest consumer sector of the steel industry and the least affected industry in the EU this year, it is estimated that DIN 17102 TStE285 steel hardness steel consumption will account for 35% of the EU steel consumption market this year. Uestf forecasts that the output of the construction industry will decline by 5.3% in 2020 and rise by 4% in 2021.
The basic phases of DIN 17102 TStE285 steel hardness, structural steel in the annealed state are ferrite and carbide. The alloy elements are dissolved in ferrite to form alloy ferrite, which depends on solid solution strengthening to increase strength and hardness, but at the same time reduce plasticity and toughness. The addition of alloying elements reduces the carbon content of the eutectoid point, which increases the proportion of pearlite in the structure and reduces the distance of the pearlite layer. This also increases the strength of the steel and reduces the plasticity.
Safety awareness is the basic understanding and thinking of safety in people's mind, which directly affects people's behavior and habits. In the report of the 19th National Congress of the Communist Party of China, General Secretary Xi clearly pointed out: Establish the concept of safe development and promote the idea of life first and safety first. Therefore, improving employees' safety awareness is an important way for steel companies to strengthen safety management. First, there must be a correct understanding. Ensuring personal safety is not only to ensure safe production, improve corporate efficiency, and promote corporate development, but also to be responsible to relatives, to the family, and most importantly to oneself.
