Corrosion Behavior of SMA490BW Steel and Welded Joints

Currently, high-speed trains work under various atmospheric environments, and the bogie as a key component suffers serious corrosion. To investigate the corrosion behavior of bogies in industrial atmospheric environments, the periodic immersion wet/dry cyclic corrosion test for SMA490BW steel and automatic metal active gas (MAG) welded joints used for bogies was conducted in the present work. Dissimilar Metal Joining of 304 Stainless Steel to Aug 01, 2019 · SMA490BW steel is a common material in the bogies of rail vehicles , which has good mechanical properties and corrosion resistance. However, sometimes SMA490BW steel is difficult to meet the service requirements of low temperature and humid environment. Effect of Welding Heat Cycle Peak Temperature and Heat Welding thermal cycle of SMA490BW corrosion resistance steel with different heat inputs were simulated by using Gleeble-3500 thermo-mechanical simulator to investigate the grain size of the heat affected zone (HAZ). Results show that welding heat cycle peak temperature has great influence on the grain size with the same other conditions, the higher peak temperature is the bigger grain size is

Effect of ultrasonic impact treatment on the ultra high

Jun 22, 2017 · Effect of ultrasonic impact treatment on ultra high cycle fatigue properties of SMA490BW steel welded joints was studied from the aspects of stress concentration of weld toe, residual stress distribution, and surface grain size. The results show that the ultrasonic impact treatment can significantly improve the high cycle and very high cycle fatigue strength of welded joints. Finish boring process of hard alloy cutter based on Nov 06, 2020 · Boring process of air spring hole. As shown in Fig. 1a, the air spring hole is a step-type blind hole made of SMA490BW low-carbon alloy steel.Four connecting holes are arranged at the bottom of the sample to facilitate connection with the three-way cutting dynamometer, and the temperature measuring hole is a thermocouple jack. PAPER OPEN ACCESS SMA490BW 490MPa 355MPa 2.0×105MPa 0.29 7800kg/m3 In this paper, referring to the geometric parameters of SKMB-200 bogie frame, the 3D solid model is established in Solidworks, as shown in Figure 1. Then the model is saved as IGES format and imported into ABAQUS for grid division.
