A588 Grade B corrosion resistant steel bars Iron And Steel Industry Report

How to distinguish between hot rolled and cold rolled process? The hot-rolled steel sheet has low strength, easy production and processing, and good plasticity. The process performance of the hot-rolled steel plate is poor (air oxidation and low smoothness), but the plastic deformation is good. Generally, it is medium and thick plate, A588 Grade B corrosion resistant steel bars, high compressive strength, high strength, and high surface smoothness. Cold-rolled steel sheets have high strength and relatively difficult production and processing, but they are not easy to deform and have high compressive strength.

The basic phases of A588 Grade B corrosion resistant steel bars, 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.

Strengthen system construction. The system itself has a certain binding force, which specifies the rights and obligations of employees. It is a passive management means for employees. Its purpose is to promote each employee to develop good professional habits, form good behavior norms, and promote the improvement of enterprise management level.
