Processing information

Cold bending

Cold bending: Cold forming of IMEX 900 should be carried out according to the following recommendations:

Internal minimum radius V block opening minimum
Transversal 3 x th 9 x th
Longitudinal 4 x th 12 x th

Hot forming

This grade is not suitable for hot forming.

Flame cutting

For flame cutting, the following minimum preheating temperatures are recommended: 50 °C for plate thickness up to 25 mm, 100 °C for plates thickness up to 50 mm and 150 °C for thicker plates.

Applications

This material is particularly used in welded steel structures in mechanical manufactured items, plant constructions, and chassis.
