Cold-rolled steel sheets
1320・1470MPa grade Cold-rolled Ultra High Strength Steel Sheets
Features
- Ultra high strength is achieved by a fully martensite microstructure.
- Excellent spot-weldability, superior bendability and excellent delayed fracture properties
are delivered with low alloy design via the WQ (Water-Quench)-CAL process. - Steel sheets can be made in thin thicknesses and wide widths using a low alloy design.
Example of Product Characteristics
Mechanical properties
The high strength steel sheets with superior bendability are suitable for bending and roll-forming.
Impact resistance strength
High yield strength over 1200MPa enables very high impact resistance strength.
Examples of Applicable Automotive Parts
Cold-rolled steel sheet with the world’s highest strength
Bumper reinforcements and door impact beams must be made with high strength steel sheets to minimize damage in collisions and protect vehicle occupants.
These cold-rolled steel sheets with the world’s highest strength have excellent spot-weldability, superior bendability and excellent delayed fracture properties.
These steel sheets can be an alternative to steels for hot stamping because of the high yield strength.
