Automotive Axle Housing Steel
The automotive axle housing steel is dedicatedly used in back axle of the car, the customer requires it to be with high strength, good formability and fatigue property.
Delivery standard is Q/OHAC814-2017 automotive axle structural sheet and strip
Main grades and mechanical property
| Steel grade | Supply grade and dimension | Yield strength (MPa) | Tensile strength ( MPa) | Elongation (%) | 180 °Cold bending, b=35mm | Longitudinal impact energy (-20℃/J) |
| LG510QK | 4.0-18.5×1000—2050mm | ≥355 | 500~630 | ≥22 | d=1.0a | ≥34 |
| LG600QK | ≥460 | 590-720 | ≥20 | d=1.5a | ≥34 | |
| LG650QK | ≥500 | 640-820 | 17 | d=2.0a | ≥34 | |
Remark:1.a is thickness of the sample, b is width of the cold bending sample, d is bending diameter. 2）The direction of the tensile sample is transverse, i.e.P10 sample in GB/T 228. The direction of the cold bending sample is transverse, i.e. GB/T 232 flap type test.the direction of impact is longitudinal | ||||||
