EFFECT OF CURRENT INTENSITY ON RESIDUAL STRESS

Anshan, Liaoning, X. Zhang, S. Bian, China T. Kang, 725 Research Institute of China Shipbuilding Heavy Industry Group Corporation, China Based on the software Visual-Environment, Finite element method (FEM) was performed on the dissimilar butt-joint between Q345 and 2Cr13 steel aiming at the welding residual stress. GB/T1591 Q345B Low Alloy High Strength Steel Plate, Coils Dec 17, 2018 · Q345B steel plate, steel coil, angle steel, round bar is offered by the china united iron and steel limited. They are the leading manufacturer of the high-grade industrial equipment. They are offering products in a wide range of standards, specifications, sizes, and dimensions.

Material properties of Q345 (16Mn) steel under loading and

To investigate the mechanical properties of the Q345 (16Mn) steel made in China, steady state tests were carried out by using computer controlled test machine, heating device and Material properties of Q345(16Mn)steel under loading and To investigate the mechanical properties of the Q345(16Mn)steel made in China,steady state tests were carried out by using computer controlled test machine,heating device and specially designed deformation measuring appliance,with the 152 steel specimens coming from 10 factories.The variations of mechanical properties of the steel within 600 were revealed.The secant-intersection method was Q235 vs Q345 Strength? - Structural engineering general Sep 28, 2010 · There are also different 4 grades of Q235 and 5 grades of Q345 which have varying carbon content. The PRC Steel Design Code GB 50009 uses a value of E = 206,000 MPa (29,877,774 psi). Perhaps the steel mill in China could provide you with some more specific material data.

Q345 Steel Equivalent Materials & Metal Specifications

Dec 16, 2020 · For Q345, the yield strength is 345 MPa. Like many in its grade, it will endure elongation before pulling apart, which typically occurs at 20 percent of its initial length. Q345 has a tensile strength rating of 470 to 660 MPa, which means that it can handle heavy-duty stress and use before ever failing.
