Do you know features of SPA-C weathering steel plate

With the rapid development of economy, there are many kinds of engineering projects, and their development is very fast. However, steel is an essential material in construction engineering. At present, there are many kinds of steel products on the market. In order to ensure the construction quality, the requirements for the strength, quality and corrosion resistance of SPA-C weathering steel plate, steel are more and more strict.

Oxygen is a harmful element in SPA-C weathering steel plate steel. With the increase of oxygen content, the strength of SPA-C weathering steel plate steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of SPA-C weathering steel plate steel.

South Korean SPA-C weathering steel plate steel industry said that the slowdown in economic growth superimposed on the impact of the epidemic, steel demand weakened, exports were sluggish, enterprises are facing huge operating pressure. Due to the delay in the resumption of work of Chinese SPA-C weathering steel plate steel enterprises, the steel inventory is growing rapidly. According to statistics, China's steel circulation inventory reached 23.75 million tons in February, the highest since 2006, with an estimated total inventory of 33.45 million tons.
