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.
Applications
- Agricultural machinery
- Automotive components
- Containers
- Cranes and crane booms
- Earth-moving equipment
- Lightweight towers
- Radiator components
- Safety-critical applications
- Racking and shelving
- Telescopic booms
- Tow hooks
- Train carriages
