2022年12月13日 · 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., “low carbon” and “high carbon” steels.

Steel is a popular material for axle shafts because it's strong, long-lasting, and affordable. Steel can handle strong twisting forces, which is important for vehicles. It doesn't wear out easily, so it lasts a long time. Plus, steel is easy to get and won't break the bank, so it's a smart choice for making axle shafts.

铁路车轴钢 (axle steel for railway)用于制造铁路机车和 车辆 车轴的专业用钢。 车轴是承受机车、车辆质量的关键部件，在运行中承受旋转弯曲和冲击等多项复杂应力，疲劳裂损是其主要破坏 …

Axles are typically made from SAE grade 41xx steel or SAE grade 10xx steel. SAE grade 41xx steel is commonly known as "chrome-molybdenum steel" (or "chrome-moly") while SAE grade 10xx steel is known as "carbon steel".

2023年9月1日 · The DZ2 axle steel has a heterogeneous band structure consisting of equiaxed grain and lath morphology tempered martensite. When being impacted at the strain rate range from 500 s −1 to 2440 s −1, its yield strength, compressive strength, and plastic strain increase.

2022年10月29日 · The two main steel grades: low carbon steels for commuter trains and high strength low alloy steels for high-speed trains have ferrite-pearlite microstructures with 20-40 mm ferrite grain sizes....

2023年7月1日 · CFB axle steel shows better excellent fatigue properties than DZ2 axle steel. Crack deflection, secondary crack and grain bridging enhance FCG resistance of DZ2. FCG behavior of CFB steel depends on the long axis direction of bainitic lath. Deformation induced martensitic transformation enhances the crack-tip shielding.
