Therefore, the tensile test of Q345 steel naturally cooled at room temperature (20C, 250C, 500C and 750C) was conducted in this paper to study the variation rule of mechanical properties parameters of Q345 steel naturally cooled at high temperature, so as to provide a basis for the evaluation and reinforcement of Q345 steel building Experimental investigation into the post-fire mechanical Jun 01, 2016 · 1. Introduction. Hot-rolled Q235, Q345, and Q420 steel members have been applied extensively as load-bearing members in building structures. For instance, the beams, columns, and joints in most steel residential and industrial buildings in China are currently made of either Q235 or Q345 steel; meanwhile, Q420 is mainly used extensively in high-rise buildings. Experimental investigation of post-fire mechanical May 01, 2020 · Test results of post-fire mechanical properties are presented. Moreover, evolution of microstructure and fracture morphology of specimens with different cooling methods were examined. Finally, predictive equations are proposed for evaluating the post-fire mechanical properties of Q235 cold-formed steel channel sections.
The lower limit of yield strength of Q235 is 235Mpa, and that of Q345 is 345Mpa (Q means qu in Chinese, and the following value represents the lower limit of yield strength). They have different gold content:Q235 is ordinary carbon steel, Q345 is low alloy steel.

Mechanical properties of chinese low alloy steel q345b,chinese construction equipment material Q345B steel is a Chinese standardized low alloy, medium tensile strength steel made with a hot-rolling process, Q345 steel property and specification are equivalent to Q345 steel is one kind of Chinese standardized low alloy, medium tensile strength steel made with a hot-rolling process, used for a number of manufacturing purposes. To some extent, the Q345 possesses the same property and composition of ASME A572, namely the Q345 is equivalent to A572.
May 11, 2012 · Structural steel is a standard construction material made from specific grades of steel and formed in a range of industry-standard cross-sectional shapes (or Sections). Structural steel grades are designed with specific chemical compositions and mechanical properties formulated for particular applications.
