What is the application of SA203 Gr.D steel?

SA203 Gr.D steel is an American standard pressure vessel plate. The standard ASMT SA203 Gr.D is divided into five grades: A, B, D, E, and F. Among them, D, E, and F have good impact toughness and mechanical properties under low temperature conditions. The delivery status of SA203 Gr.D steel plate is generally normalized, normalized and tempered or quenched and tempered. The SA203 Gr.D grade belongs to the Military Industry Institute of the Science and Technology Department of Wuyang Steel Plant, and is the exclusive national defense military steel plate of the Science and Technology Department.

SA203 Gr.D steel is a steel plate for low-temperature pressure vessels, which is mainly used to manufacture air separation oxygen equipment and ammonia synthesis equipment. The domestic annual output is about 30,000 tons. Prior to this, the SA203 Gr.D steel plate has been dependent on imports and is relatively high. It has taken the development and production of steel plates that are urgently needed for the construction of major national projects as its own responsibility, and carefully organizes the research and development of this steel.
