Ympress is the brand name for the series of hot-rolled High-Strength Low-Alloy steel developed and manufactured by Tata Steel Strip Products IJmuiden. Through customer focus the Ympress range has been continuously improved and widened to match the increasing requirements of our customers. Ympress delivers high strength steel with consistent properties, excellent surface quality and high formability. To ensure an optimum match with standards, all grades have been designed to meet or exceed specifications conform EN 10149.
We offer a wide range of strength levels between S315MC up to S700MC and a broad dimensional range with gauges between 1.5 and 20 mm and widths up to 2070 mm. Because of the wide dimensional range and the number of strength levels included in the Ympress brand, Ympress can be used for many applications ranging from construction profiles to crane booms. |

Ympress Benefits |
|
|
The consistency in chemical composition and production conditions provide the basis for the consistency in product properties of Ympress. Through its properties Ympress contributes to an optimum and efficient processing and high quality finished products.
- Formability:
The precise control of the sulphur content prevents the formation of MnS particles resulting in improved bending characteristics for Ympress. Even the use of a very small bending radius (0t) is possible for many strength levels. The guaranteed elongation levels are leading in the European industry.
- Consistency:
Ympress' consistent properties and narrow gauge control ensure the same bending behaviour from sheet to sheet and from coil to coil. This reduces the intermediate setup times for tooling and increases efficiency.
- Welding:
The guaranteed low carbon equivalent allows Ympress to be welded trouble free with the commonly used welding methods. Pre- or post heating of the steel is therefore not necessary.
- Galvanising:
Most Ympress can directly be galvanised, the very low silicon content prevents the formation of surface defects by the Sandelin effect. For the highest strength levels E690TM and S700MC it is recommended to test the galvanising conditions first.
- Laser cutting:
For the optimisation of your laser cutting process we recommend the use of Ympress Laser. Ympress Laser is a superior product because of the low tensions in the material, the low silicon content and the extra high surface quality.
- High surface quality:
The low silicon content of all Ympress grades avoids the formation of so called 'tiger stripes' . The high quality surface can lead to fewer processing steps during manufacture.
- Expert Service:
For support in the areas of welding, cutting or forming of Ympress products, our dedicated support engineers and research staff are ready to help.
