ASTM A441, used in low-tolerance, state-of-the-art structures, such as towers and large telescopes, A588 Gr A heavy plate is a high-strength structural grade with a yield strength of 40,000 to 50,000 psi and an allowable bending stress of 24,000 to 30,000 psi.
The basic phases of A588 Gr A heavy plate, 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.
Looking to the future, our company will make its main business more competitive while carrying out diversified, extensive, green and harmonious development modes, so as to be the most competitive A588 Gr A heavy plate producer in the world as well as a worldwide first-class enterprise. With ten years cooperation with these big mills, now we are the agent of super stainless steel mills in China.
