EN steel grade S275NL material yield strength psi

JIS G3101 EN steel grade S275NL material belongs to ordinary carbon structural steel grade, and the other grades of JIS G3101 are SS330, SS490, EN steel grade S275NL material and SS540. Related product types include steel plate, steel plate, section steel, steel pipe, etc.

Rolled sheet is a very common material in industrial construction. Rolled sheet at room temperature is cold-rolled sheet, and cold-rolled sheet is the rolling of hot-rolled coils below the recrystallization temperature. The hot-rolled sheet is rolled above the recrystallization temperature. So what is the difference between EN steel grade S275NL material, hot rolled sheet and cold rolled sheet?

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 EN steel grade S275NL material 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.

The rise and fall of EN steel grade S275NL material, steel pipe price will be affected by many factors, such as market demand. If the construction of real estate industry, basic road construction and so on industries is booming, the sales volume of steel pipes will be very good, and the market supply will gradually increase. The market demand has a very important guiding significance for EN steel grade S275NL material, steel pipe manufacturers, dealers and agents in many regions.
