Welcome to BBN High Strength Steels Factory
S690Q steel material has more restrictions on the chemical elements P and S, the maximum P% is 0.025, and the maximum S% is 0.015. The same restrictions apply to other major alloying elements. S690QL board has higher effective load capacity and energy efficiency, so it can be used in a more streamlined structure.In addition to the necessary impact test, the ultrasonic test of S690Q steel plate is an additional technical term, which should be tested according to ASTM A578/A578M, A588/A588M or A435/A435M.
S690Q steel is used for structures that withstand extreme loads: mining and heavy construction equipment, crane equipment, offshore drilling platforms, wind turbines, bridges and trestle supporting structures
