09cuptire-a corrosion steel for engineering steel
Over the years, the company has trained a number of professional sales talents, enriched the concept of various marketing and customer service, and strengthened the business strength of the company. Now the company's business 09CUPTIRE-A corrosion steel department, marketing department and information department constitute the market development network; the finance department, personnel department, logistics department, shipping department, document department and 09CUPTIRE-A corrosion steel after-sales service department constitute the service customer network.
Hot rolled 09CUPTIRE-A corrosion steel steel coil and plates are among our main products. Hot rolling can significantly reduce energy consumption and cost. During hot rolling, the metal has high plasticity and low deformation resistance, which greatly reduces the energy consumption of metal deformation. Hot rolling can improve the 09CUPTIRE-A corrosion steel processing properties of metals and alloys, that is, the coarse grains in the casting state are broken, cracks are obviously healed, casting defects are reduced or eliminated, the as cast structure is transformed into deformed structure, and the processing properties of alloys are improved.
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 09CUPTIRE-A corrosion steel, hot rolled sheet and cold rolled sheet?
Q355GNH weathering steel: Q——The first letter of the Chinese pinyin of "Qu" in the yield strength;355——The lower limit of the lower yield strength of steel, in N/mm²;GNH——respectively the first letter of "Gao, Nai, Hou" Chinese Pinyin;Quality grades are divided into A, B, C, D, E(1)Q355GNH executive standard: GB/T 4171-2008(2)Q355GNH smelting method: the steel is smelted by converter or electric furnace, and it is killed steel.
