Guidance for forming of structural steels in processing

This CEN Technical Report provides guidance for forming during processing of structural steel products conforming to EN 10025 Parts 2 to 6 and EN 10149 Parts 2 and 3. This Technical Report covers hot and cold forming processes and local hot forming used in flame-straightening operations.
This Technical Report does not cover the special measures necessary for the fabrication of structural components that are subjected predominantly to alternating stresses or that come into contact with aggressive media.

CEN/TR 10347:2006 (E)
Foreword
This Technical Report (CEN/TR 10347:2006) has been prepared by Technical Committee ECISS/TC 10
"Structural steels – Grades and qualities", the secretariat of which is held by NEN.
In the ECISS/TC 10 meeting of 8 and 9 December 1998 it was decided with Resolution
ECISS/TC 10 no 2/1998 to publish ECSC IC 2 as a CEN report. The part on welding in ECSC IC 2 has been
revised by CEN/TC 121 and has resulted in EN 1011-2. The part on formability has been revised in this CEN
Technical Report.

1 Scope
This CEN Technical Report provides guidance for forming during processing of structural steel products
conforming to EN 10025 Parts 2 to 6 and EN 10149 Parts 2 and 3. This Technical Report covers hot and cold
forming processes and local hot forming used in flame-straightening operations.
This Technical Report does not cover the special measures necessary for the fabrication of structural
components that are subjected predominantly to alternating stresses or that come into contact with aggressive
media.
2 Terms and definitions
For the purposes of this Technical Report, the following terms and definitions apply.
2.1
hot forming
forming at temperatures in the austenite range, generally around 900 °C depending on the chemical
composition of the steel grade
2.2
cold forming
forming up to the highest temperature permissible for stress relieving, generally in the range of 530 °C to
580 °C
NOTE See the relevant part of EN 10025 (e.g. 7.3.1.1 of EN 10025-1:2004 and 7.4.1.1 of EN 10149-1:1995).
2.3
flame-straightening
local quick heating of a component with a short holding time (generally less than one minute) at the flame-
straightening temperature
2.4
flame-straightening temperature
highest temperature arising in the component during flame-straightening
3 General principles
With rising minimum
