BBN export S690QL vs S690QL1 steel more than 10000 tons

The whole plant covers an area of 18,480 square meters, a workshop area of 9,500 square meters, and a final assembly workshop of 4,300 square meters; fixed assets are 25.50 million yuan. The company has S690QL vs S690QL1 strong technical force, complete quality assurance system sophisticated tooling equipment and advanced technology. It can provide high efficiency professional equipment and S690QL vs S690QL1 pressure vessels for domestic and foreign chemical, petroleum, chemical, metallurgical, pharmaceutical, fertilizer, textile, and environmental protection industries.

Chemical composition of S690QL vs S690QL1, A514 Gr P steel plate (melting analysis %)
C: 0.14-0.18 Mn: 1.20 V: 0.03-0.08 Si: 0.10-.040 P: 0.025 S: 0.020 Cr: 1.0-1.5 Mo: 0.4-0.6
Mechanical properties of A514 Gr P steel plate:
Yield strength≥690MPa, tensile strength≥760-896MPa, elongation %≥16, Akv2 J / longitudinal ≥34, impact temperature - 40℃.

The selection principle of steel plate for high-rise building is: it can not only make the structure safe and reliable, but also can save steel and reduce the cost. Different use conditions should have different quality requirements. In terms of the mechanical properties of steel such as S690QL vs S690QL1, yield point, tensile strength, elongation, cold bending property, impact toughness etc. are the indicators to measure the quality of steel. In the design of steel structure, the appropriate steel should be selected according to the characteristics of the structure. The selection of steel is not only an economic problem, but also related to the safety and service life of the structure.
