Welcome to Henan BBN Steel
20# steel belongs to high-quality carbon steel.No. 20 steel means steel with an average carbon content of 0.20%;The thermal conductivity of 20# steel at 315℃ is 48 W/m℃;No. 20 steel is generally not quenched, the general treatment method is carburizing or normalizing;The yield strength of 20# steel is not less than 250MPa;The tensile strength of 20# steel is not less than 420MPa;Elongation of No. 20 steel is not less than 25%;The reduction of area is not less than 55%;The density of steel s275j0 and 20# steel is 7.85kg/cm3
Classification of hot rolled steel plate: hot rolled steel plate can be divided into steel s275j0 ordinary thin steel plate, pickling thin steel plate, roofing plate, oil barrel plate, pattern steel plate, shipbuilding steel plate and automobile steel plate according to its use.
Since it was established in 2000. Based on the domestic rich steel s275j0 product resources and the great steel demand of the international market, our steel s275j0 service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products
Recently, the price of steel s275j0 raw materials has been strong, the mainstream steel mills have raised the price, and the cost of taking goods by steel s275j0 merchants has risen. In addition, macro capital will still have a disturbance to the market, and the current wait-and-see sentiment of downstream and middlemen is strong. On the whole, the steel market is intertwined with many spaces, and the supply and demand fundamentals are generally in a weak balance pattern. High inventory suppresses the price of steel s275j0 steel, and high cost supports the price of steel s275j0 steel, while macro capital also disturbs the market from time to time. In the short term, the market wait-and-see sentiment is strong, steel s275j0 steel prices or continue to fluctuate, the range of rise and fall are limited.
