EN_US-Engineering-Product-Hot-Rolled-HSS-Ympress grades OverviewTSN
Our high-strength steel grades have been developed to meet a wide variety of applications. The consistent quality of these steels means they can be relied on to deliver benefits for your end products and processes.
The high yield strength of Ympress delivers weight savings and increased component strength. This can help you create lighter, stronger products and increase yield through down-gauging. Consistent properties and tight control of material thickness allow trouble-free, repeatable processing. Ympress can be easily welded and galvanised. Its high surface quality can lead to fewer processing steps.

- Automotive components
- Containers
- Cranes and crane booms
- Earth-moving equipment
- Lightweight towers
- Radiator components
- Safety-critical applications
- Racking and shelving

Properties
Mechanical properties
The values below show the guaranteed mechanical properties of Ympress. Ympress products guarantee tighter limits than ASTM A1011/A1018. The values shown for the mechanical properties in the table below are for test pieces taken longitudinal to the rolling direction unless shown otherwise. The values of the bend test apply to test bars transverse to the rolling direction.
