Galvanized Q345 steel specimens were accelerating corroded with accelerating environment spectrum for equivalent 1, 3, 4 and 5 years, and then its corrosion behavior was studied based on macro corrosion appearances, micro corrosion appearances, weight loss, pits depth and fatigue strength. The results show that, i because the zinc coating can protect the matrix metal from corroding, the China Structural Steel H Beam (A36, SS400, Q235B, Q345B Steel Beam, Steel Column, Building Material manufacturer / supplier in China, offering Structural Steel H Beam (A36, SS400, Q235B, Q345B, S235JR, S355), Steel Structure Construction Materials Round Pipe Prefabricated Steel Column Beams Fabrication, Shelves Metal Warehouse Storage Plant Frame Construction and so on.
Mar 31, 2016 · A total number of 44 fatigue tests were conducted under total stain control, 26 for G20Mn5QT cast steel and 18 for butt welds between G20Mn5QT cast steel and Q345B steel. Based on the test results, cyclic stress response, plastic strain energy, strainlife curves and Coffin-Manson equations were presented. Comparing with hot rolled steels widely used in steel construction, the Metal Magnetic Memory Inspection of Q345 Steel Metal magnetic memory (MMM) method is a non-destructive testing method based on the analysis of self-magnetic-leakage field (SMLF) distribution on components surfaces. The MMM method can determine stress concentration zones, imperfections, and heterogeneity in the microstructure of the material and in welded joints. In order to study the magnetization of defective and non-defective butt Overview of Q235 Steel Plate SpecificationQ235 steel is equivalent to Japenese steel grade SS400 in application, the only difference is that ss400 steel requires only S,P composition < 0.050, Q235 has requirements for More element C, Si, Mn, S, P. Yield strength of q235 is >235Mpa, which is almost the same to SS400 245Mpa. Q represents the yield of this material, the latter 235, refers to the yield value of this material, at about 235MPA.

However, for stability control design, Q235 steel is better. The price difference is 3%- 8%. Regarding how to distinguish the steel plate from Q235 and Q345, therere several methods: Q345 Steel Specification and Equivalent StandardQ345 steel specification:Q345 steel belongs to 16Mn steel grade, usually it is produced in hot rolled state, hot rolled steel plate, hot rolled steel coil/sheet, it has comprehensive mechanical and welding property, as it shows good performance in structural purposes, it is widely used as welding structural part in manufacturing of ship, railway and vehicles, bridges, boiler, pressure vessel
