High-Strength Hot Stamping Steel
This grade is uncoated and can be delivered as hot rolled or pickled. After hot stamping, the grade is high strength which can be applied in anticollision parts in passenger car or in parts, axle housing, wheel in commercial vehicle that ask for lightweight, sharply reducing vehicle weight
| Grade | Supply grade and dimension | State | Yield strength (MPa) | Tensile Tensile strength (MPa) | Elongation A (%) | 180° Bending test b=35mm |
| LR1500HS | 1.4-8.0× 900-2000mm | Before thermal forming | ≥320 | ≤800 | ≥16 | d=2a |
| After thermal forming | ≥1150 | ≥1480 | ≥5 | d=4a | ||
Remark: 1）a is test thickness, b is the width of the cold bending test, and d is bending diameter. 2）The direction of the tensile sample is transverse, i.e. P10 sample in GB/T 228. The direction of cold bending is transverse, i.e. GB/T 232 flap type test. | ||||||
