The basic phases of SA283 Grade D equivalent for hull structures, 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.

It is a modern high-tech professional enterprise integrating scientific research, production and sales.
S355J0 is a kind of carbon structural steel plate produced by European standard. It is similar to Q345B steel plate in performance, composition and application. However, some details of these two kinds of steel plates are different, which can not be completely replaced. SA283 Grade D equivalent for hull structures, S355J0 steel is used in buildings, bridges, ships, vehicles and other structures.
On November 25, the price of the SA283 Grade D equivalent for hull structures medium board in the Yinchuan market remained stable temporarily, and the market transactions were average. As of press time, Yinchuan market 16-25mm general medium plate is 4020 yuan/ton; 14-25mm low alloy medium plate is 4170 yuan/ton. The price of plate in Yinchuan market continued to stabilize without much change. However, as the temperature dropped sharply and terminal demand in the local market dropped to a low point, plate merchants in the Yinchuan market had difficulty shipping.
