Welcome to Tata Steel Strip Products IJmuiden

The specified values for wide strip do not apply to the uncropped ends of the coil ('head' and 'tail'). The length of these uncropped ends is calculated using the following formula:
length (in metres) = 90/nominal thickness (in mm), with a maximum of 20 metres.

If required, this part of the coil can be removed.

Tolerances on thickness

Thickness hot-rolled steel with a low carbon content for cold forming (applies to EN 10111)

Dimensions in mm:

Nominal Thickness		Tolerances for a nominal width of
		≤ 1200	> 1200	> 1500	> 1800
			≤ 1500	≤ 1800
> 1.47	≤ 2.00	± 0.13	± 0.14	± 0.16	-
> 2.00	≤ 2.50	± 0.14	± 0.16	± 0.17	± 0.19
> 2.50	≤ 3.00	± 0.15	± 0.17	± 0.18	± 0.20

> 6.00	≤ 8.00	± 0.22	± 0.23	± 0.23	± 0.26

Option for maximum crown values

At the time of ordering, specific agreements can be made on the crown of hot-rolled strip.

Thickness of steel grades with normal deformation resistance (applies to other standards)

As a rule Tata Steel Strip Products IJmuiden delivers 75% of EN 10051. Closer tolerance of 60% of EN 10051 is possible after consultation.

Tolerances of grades with a specified yield strength ≥ 350 N/mm² are increased by 15%

Tolerances of grades with a specified yield strength ≥ 420 N/mm² are increased by 30%

Tolerances of grades with a specified yield strength > 460 N/mm² are increased by 40%

Option for maximum crown values
At the time of ordering, specific agreements can be made on the crown of hot-rolled strip.

Tolerances on Width
Dimensions in mm:

Nominal width		Tolerances mill edges		Tolerances trimmed edges
		lower	upper	lower	upper
≥ 700	≤ 1200	0	+20	0	+3
> 1200	≤ 1500	0	+20	0	+5
> 1500	≤ 2070	0	+25	0	+6

Flatness
Requirements as regards flatness can be agreed at the time of ordering.

Edge camber
The deviation from the edge over a length of 5000 mm:

with mill edges
no more than 20 mm
with trimmed edges
no more than 15 mm
