hot-rolled coil Q345C carbon steel plate sheet production line

We have a stable system and professional human resource management work as the support, from the six aspects of guidance, cohesion, incentive, constraint, radiation and stability, we continue to introduce, modify and train employees from concept to action, and shape employees through constant guidance of common values.

Q345C carbon steel plate sheet, No. 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 No. 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 No. 20 steel is not less than 250MPa;The tensile strength of No. 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 Q345C carbon steel plate sheet and No. 20 steel is 7.85kg/cm3

The final heat treatment of quenched and tempered alloy steel, Q345C carbon steel plate sheet is quenching and high temperature tempering. The hardenability of quenched and tempered alloy steel is high, and oil is generally used. When the hardenability is very high, it can even be air cooled, which can reduce the defects of heat treatment. The final properties of quenched and tempered alloy steel depend on tempering temperature. Generally, it is tempered at 500 ℃ - 650 ℃. The required properties can be obtained by selecting tempering temperature. In order to prevent the second kind of temper brittleness, fast cooling (water cooling or oil cooling) after tempering is beneficial to the improvement of toughness.

On Jan. 31, 2019, BBN steel held the annual meeting with all employees, family members, and friends. It is a moment of joyand it is a moment to summarize the past and look forward.Looking back on 2018, BBN steel exported Q345C carbon steel plate sheet more than 2 million tons of steel materials to all parts of the world and made outstanding contributions to infrastructure construction at home and abroad. In 2019, BBN steel will make persistent efforts and forge ahead.

Every after-sales service shall have a detailed record of the customer's product problems and handling methods. The records shall be sorted into volumes and filed on a monthly basis, and submitted to the technical department for filing. The problems found in the after-sales service shall be summarized in a timely manner, discussed with the technical department, the quality inspection department and the production department, and a proper solution shall be proposed for the technical department to improve in a timely manner;

According to a statistical study, Iran has decided to produce 33 million tons of steel in its calendar year (from March 20, 2020). A study of the performance of the mining sector affiliated to the mining and mining development and transformation organization of Iran (imidro) in the first month of the year (March 20 to April 20) shows that this month produced 5.4% of the 33 million tons produced at the end of this year. In the first month of this year, relevant enterprises in the country produced about 1797927 tons of steel, including Q345C carbon steel plate sheet, an increase of 1% over the same period last year. Iran has become a leading country in the field of steel production and export in the Middle East. Iran's steel industry has more than half a century of experience and is a leader in steel production and export in the Middle East.
