The mechanical properties of steel after high temperature are the basis for the safety assessment of steel structure after fire. Therefore, this paper studies the mechanical properties of Q345 steel after high temperature cooling. Because of its advantages of light weight, high strength and convenient construction, steel structure has gradually Galvanized Q345b Q235 Mechanical Properties - Buy Q235 Galvanized Q345b Q235 Mechanical Properties , Find Complete Details about Galvanized Q345b Q235 Mechanical Properties,Q235 Mechanical Properties,Q345b Mechanical Properties,Q235 Material Properties from Steel Pipes Supplier or Manufacturer-Tianjin Jinnuo Steel Pipe Co., Ltd.
The chemical composition of Q235 steel:C 0.22, Si 0.35, Mn 1.40, P 0.045, S 0.050. 2. The prices of Q345B carbon steel plate sheet, Q235 steel is higher than that of Q195 steel. 3. The mechanical properties of Q195 and Q235 steel are different. Q235 Steel Equivalent, Properties, Specification, CompositionQ235 Steel (Q235A Q235B Q235C Q235D) Q235 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). Q235B Included in 3 standards (China) - MetalDatafoProperties By GB/T 700-2006 For section of thickness >100mm is allowed to reduce the lower limit of strength up to 20N/mm2 Thickness:< 16 mm ; Yield Strength:> 235 MPa Tensile Strength:370 - 500 MPa Elongation:> 26 % Impact energy KV 20° :> 27 J Thickness:16 - 40 mm ; Yield Strength:> 225 MPa Tensile Strength:370 - 500 MPa Elongation:> 26 %
