Behavior of Q690 high-strength steel columns:Part 1

The measured retention factors for the material yield stress of S690 high strength steel f y,T /f y , together with those reported in Qiang et al. [11], Li et al. [12] and Li and Young [13], are EN 10025-6 S690Q strength steel fasteners - Steel Material Oct 12, 2020 · S690QL A high power structural steel equipped in quenched and tempered condition. Our S690Q is a structural steel grade and is produced to give high yield strength during usage. The material can be heat treated using quench and temper techniques. These EN 10025 6 Plates have good forming and welding properties. Effects of the Arctic low temperature on mechanical Recently, high strength constructional materials become popular on developing high-performance structures, e.g., high-strength steel (HSS) , . Benefiting from the advances of steel technology, HSS with yield strength over 600 MPa or even over 1000 MPa, e.g., Q690, Q960, S690, S890, and S960, are available for the engineering structures in many countries [3] .

sections made of high strength Q690 steel materials Over the past few decades, many researchers investigated residual stress patterns in welded sections made of S235 to S355 steel plates. A simplified residual stress pattern for welded sections was recommended in the ECCS, and it has been widely adopted in a number of design codes.Post-fire mechanical properties of high strength Q690 May 01, 2017 · This paper investigates the post-fire mechanical properties of high strength structural steel (HSSS) of Q690, the Chinese Grade of steel with nominal yield strength of 690 MPa. The test specimens were first heated to a temperature level (ranging from 300 °C to 900 °C), and then cooled down to ambient temperature. Two cooling methods were considered:cooling in air and cooling in water.
