What is the most important characteristic of EN10025-2 carbon steel S355JR

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, EN10025-2 carbon steel S355JR is of high quality? First of all, check whether there are cracks on the surface of the EN10025-2 carbon steel S355JR 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.

Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process. They need to be heated to 1100 ° C to 1250 ° C for rolling. This EN10025-2 carbon steel S355JR rolling process is called hot rolling. Rolling at room temperature is generally understood as cold rolling. However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling.

Since the outbreak of the new crown pneumonia epidemic this year, the Iron and Steel Association has closely followed and found that, with the exception of March, the production and operation of the steel industry has maintained a positive growth despite the low rate of resumption of work and production in other industries. Superimposed on the pull of a series of national policies in the later period, the steel industry effectively supported the development of the national economy.

Hot-rolled coil is a commonly used steel product in the industry. It has a relatively wide variety of products and a wide range of uses. EN10025-2 carbon steel S355JR, Hot-rolled coils are widely used in related industries such as petrochemical equipment, automobiles and bridges. Hot-rolled coils are also used in machinery industries such as ships and automobiles because of their good toughness and relatively high strength.
