Hot-rolled steel sheets
780/980MPa grade Hot-rolled High Strength Steel Sheets for Truck Frames
Features
- This steel has excellent punchability, which presents decent sheared edges in wide range of punching clearances to give sheared edges high fatigue strength.
- Superior bendability is suitable for forming truck frame parts.
- Available thicknesses: (780MPa grade) 2.0 - 6.0mm, (980MPa grade) 2.6 - 4.0mm.
Examples of Product Characteristics
Mechanical properties
The developed steel sheets possess superior bendability and are suitable for forming truck frame parts.

Fatigue strength of sheared edge
These steel sheets show decent sheared edges in punched holes.
As a result, the fatigue strength of sheared edges, one of the most important properties for truck frame parts, has been greatly improved compared with the conventional 780MPa grade steel sheets.

Developed steels improve fatigue strength of sheared edges and reduce thickness through high strengthening
For truck frame parts, improvement of fatigue strength of sheared edges is important to reduce thickness.
These steel sheets demonstrate excellent punchability and deliver a decent punched surface in a wide range of punching clearances.
The steel sheets also exhibit superior bendability and are suitable for forming truck frame parts.
