Because it is rolled at room temperature, high weathering steel (SPA-H) without oxide scale is mainly used in the hot rolled state. spa-c hot rolled plate is widely used in the container industry. Because ordinary carbon steel is very easy to corrode in the atmosphere, causing serious economic losses, the development of weathering steel has broad market prospects.

The SPA-C weathering steel plate is a steel with higher requirements for welding performance. Steel plates often limit the P content to less than 0.04%, while using other corrosion-resistant alloy elements to replace P in the steel. A low-alloy steel A588 is used as the experimental steel. Compared with SPA-H steel, the content of P in the steel is reduced and the content of alloying elements Mn and Ni in the steel is increased. Through dry and wet weekly immersion experiments, the corrosion behavior under simulated marine atmospheric conditions and industrial atmospheric conditions is studied to provide a theoretical basis for its production and use.
