2022年12月13日 · 10XX, 11XX, 12XX, 15XX = The carbon steel group. Most standard OEM axles are 1040 grade. OEM axles are generally heat treated to 40 Rockwell in the center with the outer layer at 55-60 Rockwell to a depth of about .180 inch. These grades all carry from 1.00-1.65% manganese. The industry differentiates these steels by their carbon content, i.e ...

An axle or axletree is a central shaft for a rotating wheel or gear. On wheeled vehicles, the axle may be fixed to the wheels ... The primary differences between the two are that chrome-moly steel is significantly more resistant to bending or breaking, and is very difficult to weld with tools normally found outside a professional welding shop. ...

2023年9月1日 · This paper aimed to clarify the dynamic mechanical response, deformation, and fracture behaviors of the DZ2 axle steel under impact loadings along the diameter direction of the axle. The dynamic stress-strain characteristics and deformed microstructures of the DZ2 axle steel at high strain rates were systematically analyzed.

2023年7月1日 · In the axle steel of heavy-haul trains, the tensile strength and fatigue strength of LZ50 and LZ45CrV steel (pearlite) are 610 and 670, 290 and 336.6 MPa, respectively [10]. However, for most steels, when the tensile strength is greater than 800 MPa, its fatigue strength does not increase with the same trend as the tensile strength [11]. The ...

2022年10月29日 · This review focused on the effects of compositions and microstructure on fatigue, fretting and corrosion fatigue of rail axles. The two main steel grades: low carbon steels for commuter trains and ...

2022年10月29日 · The comparative assessments and an overview of mechanical, chemical, and physical properties of rail axles are presented. This review focused on the effects of compositions and microstructure on fatigue, fretting and corrosion fatigue of rail axles. The two main steel grades: low carbon steels for commuter trains and high strength low alloy ...

Abstract: Compared with the conventional Charpy impact test method, the oscillographic impact test can help in the behavioral analysis of materials during the fracture process. In this study, the trade-off relationship between the strength and toughness of a DZ2 axle steel at various tempering temperatures and the cause of the improvement in impact toughness was evaluated.

4 天之前 · As high-speed railway transportation advances toward increased velocities, it is imperative to enhance the mechanical performance of EA4T axle steel, especially through microstructures regulation by thermal–mechanical processing. However, little research has been conducted on the phase transformation and microstructure evolution mechanism of EA4T steel under thermal–mechanical load ...
