Overview

Ymagine^® HSLA grades

Ymagine also comes in five high-strength, low-alloy (HSLA) grades offering either weight savings or enhanced product strength without weight penalties. The consistent quality of this direct-rolled steel ensures repeatable and reliable performance.

Ymagine H500 offers excellent formability. It has been developed to meet the growing demand for strong but lightweight automotive components in gauges that are difficult to produce by conventional hot strip mills.

Shape and dimensional tolerances

Tolerances on thickness

Ymagine is available with the following tolerances.

Dimensions in mm:

Thickness	Tolerances
1.15 ≤ t ≤ 2.0	± 0.05
2.0 < t ≤ 2.5	± 0.06 ¹
2.5 < t ≤ 3.0	± 0.07 ²
3.0 < t ≤ 4.0	± 0.09 ³

^1. In some instances, the material will be supplied with a tolerance of -0.06/+0.15 mm,
only on the coil head and tail and to a maximum of 20 metres from the start of the coil.
^2. In some instances, the material will be supplied with a tolerance of -0.07/+0.17 mm,
only on the coil head and tail and to a maximum of 20 metres from the start of the coil.
^3. In some instances, the material will be supplied with a tolerance of -0.09/+0.21 mm,
only on the coil head and tail and to a maximum of 20 metres from the start of the coil.

Tolerances on width

Width tolerances comply with standard EN 10051: 2010 (hot-rolled) and
EN 10131: 2006 (cold-rolled). Closer tolerances are possible – please contact us for details.

Special width tolerances may be available (± 0.50 mm available on 750 - 2000 mm width). Please contact us for details.

Dimensions and coil weights

The weight of weld-free coils can be specified freely between 13 and 20.5 kg/mm.

Ymagine is supplied with trimmed edges as standard. Mill edges are available on request.

Description

Dimension or weight

Outside diameter

minimum 1050 mm

maximum 2000 mm (Ymagine)

maximum 2100 mm (mill scale)

Coil Weight

maximum 31.5 tonne ¹

^1.For Ymagine H500 the maximum coil weight is 25 tonne for thicknesses > 2.5 mm.
Above 3.20 mm maximum coil weight for all grades is 25 tonne. Higher coil weights available on request.

Tata Steel assumes a minimum and a maximum coil weight agreed upon with the customer on the basis of our normal production practices and an order quantity corresponding to this coil weight. Usually a minimum coil weight up to 90% of the maximum coil weight can be requested.

Surface aspects

The surface quality of Ymagine is comparable to hot-rolled pickled and oiled i.e. 1 - 3 μm Ra (cut off 2.5mm).
Ymagine is suitable for cold-rolled applications that are not surface-critical.
