ArcelorMittal Europe – Flat Products

Tolerance & conversion tables

In this section you will find designations and details of guarantees provided by ArcelorMittal in terms of tolerances in accordance with the European standards referenced.

Note: In the event of any deviation from the current standard, the latter shall prevail.

Hot rolled products

EN 10051 defines five categories:
• Table 2: Hot rolled low carbon steel sheet/plate and strip for cold forming
• Category A: Re ≤ 300 MPa
• Category B: 300 MPa < Re ≤ 360 MPa
• Category C: 360 MPa < Re ≤ 420 MPa
• Category D: 420 MPa < Re ≤ 900 MPa

The chart below can be used to calculate the outside diameters or metric weights that are compatible with your systems.
For example, if you order a 25-tonne coil, 1250 mm in width (i.e. 20 t/m), with an inside diameter of 762 mm, you can work out from the chart
that the outside diameter will be 1960 mm.
