EN 10025-5:2004 (E)

7.4.2.2 Hot forming

Only products ordered and supplied in the normalized or normalized rolled condition shall comply with the requirements of Tables 4 and 5 if hot forming is carried out after delivery (see 7.3.1.2). 7.4.2.3 Flangeability

If specified at the time of the order plate, sheet, strip, wide flats and flats (width < 150 mm) with a nominal thickness ≤ 20 mm shall be suitable for flanging without cracking with the minimum recommended bend radii given in Table 6. The grades and qualities to which this applies are given in Table 6. See option 11c.

NOTE

Cold forming leads to reduction in the ductility.

7.5 Surface properties

7.5.1 Strip

The surface condition should not impair an application appropriate to the steel grade if adequate processing of the strip is applied.

7.5.2 Plates and wide flats

EN 10163 parts 1 and 2 shall apply for the permissible surface discontinuities and for the repair of surface defects by grinding and/or welding. Class A, subclass 1 of EN 10163-2 shall apply, unless otherwise agreed at the time of the order. See option 15. 7.5.3 Sections

EN 10163 parts 1 and 3 shall apply for the permissible surface discontinuities and for the repair of surface defects by grinding and/or welding. Class C, subclass 1 of EN 10163-3 shall apply, unless otherwise agreed at the time of the order. See option 16.

7.5.4 Bars and rods

EN 10221 applies for the permissible surface discontinuities and for the repair of surface defects by grinding and/or welding. Class A of EN 10221 shall apply, unless otherwise agreed at the time of the order. See option 17.

7.6 Internal soundness

The permissible level of internal imperfections shall be in accordance with EN 10025-1. See option 6 (for flat products).

See option 7 (for H beams with parallel flanges and IPE beams). See option 8 (for bars).
