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 P355GH material properties 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.

For employees' development,  the company's transformation and development provides employees with a broad career development platform. The company needs "lion-type" entrepreneurial leaders who are full of entrepreneurial enthusiasm and dare to self-renovate. They also need a large number of professional and professional high-quality talents, and employees can get full capacity to display opportunities.

S45C steel plate chemical composition: C 0.42~0.48, Si 0.15~0.35, Mn 0.60~0.90, P≤0.030, S≤0.035, Cu≤0.30, Ni≤0.20, Cr≤0.20Mechanical properties of p355gh material properties productTensile strength>686MPaYield strength>490MPaElongation δ5>17%Shrinkage ψ>45%Impact toughness value>78J/cm2The hardness is 201~269HB.

What is the difference between Q345B steel and Q345A steel? p355gh material properties, Q345B steel and Q345A steel have slight difference in chemical composition: Q345A steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.045, S ≤ 0.045, V 0.02 ~ 0.15; Q345B steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.040, S ≤ 0.040, V 0.02 ~ 0.15. The difference between Q345B steel and Q345A steel is mainly in A and B behind the steel grade, Q345A steel grade is not subject to impact; Q345B steel grade needs 20 ℃ room temperature impact test.

The Qatar Railways company launched a tender for designing ,construction and completion of Green Line Project. Our company has participated in the bidding from Qatar Railway Company since May, 2016. A delegation from project visited several famous p355gh material properties pipe mill in China for 15 days in July,2016. Of course the delegations had visited our pipe mill.

Our company has strict quality control standards. If you want to visit our factory, you are welcome at any time! We produce a lot of steel products every month to export p355gh material properties to all over the world. Because our customers are from all countries, they will order a large number of steel products from our company every month.
