What tests need to go through in the S690QL1 steel tube production process

Mechanical properties of S355J2 plate: yield strength Rp0.2 ≥ 275MPa, tensile strength Rm: 450 - 600MPa, elongation A ≥ 18%, - 20℃ impact energy ≥ 47J, tensile section shrinkage Z ≥ 35% in thickness direction. The S690QL1 steel tube, S355J2 steel plate has excellent internal quality, high density and stable performance. S355J2 structural steel is mainly used in large machinery manufacturing, equipment base, large welded steel structure, construction, bridge and other fields.

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 S690QL1 steel tube 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.

Specification range of available steel S690QL1 steel tube: thickness ≤ 650mm, width ≤ 4500mm, length ≤ 18000mm. Larger specifications of steel plates are also available as required.
