The deoxidation ability of Al is much stronger than that of Si and Mn when aluminum element (Al element) is added into steel as deoxidizer or alloying element. The main role of aluminum in S960QL steel properties etc. steel is to refine grain size and fix nitrogen in steel, so as to significantly improve the impact toughness of steel and reduce the tendency of cold brittleness and aging. Al element can also improve the corrosion resistance of steel, especially when used with molybdenum, copper, silicon, chromium and other elements. The wear resistance of chromium molybdenum steel and chromium steel can be increased by containing Al element.

In the whole steel structure and steel body, the medium and heavy plate is an important part, once the problem occurs, it is easy to fracture, collapse and occur explosion. So how to judge whether the medium and heavy plate, S960QL steel properties is of high quality? First of all, check whether there are cracks on the surface of the S960QL steel properties plate and how glossy it is. Secondly, to measure the thickness error of medium and heavy plate, it is better to use the instrument to measure the bending tensile value. Finally, observe the scale of the steel plate manufacturers, whether there are relevant qualification certificates, and how the production process is.

The spot price of hot rolling steel rose on August 18, with a large overall increase. The average price of major cities in China is 3624 yuan / ton, up 95 yuan from last Friday. Shanghai 3520-3540 yuan / ton increased by 70 yuan, Tianjin 3600-3620 yuan / ton increased by 150 yuan, and Lecong 3650-3660 yuan / ton increased by 150 yuan. Central and southern China, North China and Northeast China rose by 90-150 yuan, while Western China rose by 30-60 yuan. The rise in spot S960QL steel properties prices led to a significant increase in transactions across the region.
