The Formation Mechanisms and Improvement Measures for Mar 29, 2020 · The dissimilar joining of QAl9-4 aluminum-bronze alloy to Q345B low carbon low alloy steel was performed by fusion welding using different techniques. The results indicated a certain amount of transverse cracks and voids in the QAl9-4/Q345B joints welded by the SMAW process, while defect-free joints were obtained using the GTAW process. The microstructure of samples produced by the Q235 Steel Q235A Q235B Q235C Q235D Equivalent,

  • Q235 SteelFeatures and ApplicationsData Sheet and SpecificationQ235 Steel EquivalentQ235 steel is a plain carbon structural steel which is widely used in China, Q235 material in Chinese standard GB/T 700 is divided into 4 quality grades:Q235A, Q235B, Q235C and Q235D; Density of this steel is 7.85 g/cm3, tensile strength is 370-500 MPa; yield strength is 235 MPa (data are for steel bar or steel plate diameter 16mm). Since its mild steel, it is used directly without heat treatment.GB/T 1591 Q345B low alloy steel plates and sectionsMain features of GB/T 1591 Q345B steel plate and sheet Q345B GB low alloy steel has good weldability, cold & hot workability and corrosion resistance.
