High-strength steels for cold-forming, thermomechanically-rolled
Usage
The steel grades of the S315MC to S700MC series are used for cold-formed components of the most varied designs. Their fields of application include the manufacture of:
- Longitudinal beams
- Frames
- Cold-pressed parts
- Cold-rolled sections
- Structural pipes
The user of these steel grades must make sure that his calculation, design and processing methods are appropriate for the material. The forming process used must be suitable for the intended application and comply with the state-of-the-art; it is of fundamental importance to the processing behaviour of these steel grades.
These low-perlite steel grades offer excellent bending, flanging, cold-bordering and folding properties in both longitudinal and transverse direction. The bending radii specified below should be observed as minimum values.

1) The tensile test values apply to longitudinal samples for QStE 340 TM and QStE 380 TM in widths
≥ 600 mm tensile test values apply to transvers samples.
2) In case the thickness is > 8 mm, the yield strength values may be reduced by 20 MPa.
3) Nominal thickness e [mm]
Notch impact energy
If agreed in the order, the notch impact energy is proved using longitudinal samples at -20 °C. The average notch impact energy from 3 samples must be 40 J minimum. One individual value may fall short of the required minimum value by not more than 30 %. The sample width shall equal the product thickness if the latter is between 5 and 10 mm, the tests being performed using samples which are similar to Charpy-V samples. The required minimum values are to be reduced proportionally to the sample width.
Heat treatment
Normalised and stress relief annealing above 580 °C with long holding times results in a reduction of yield strength and tensile strength as compared to the ‘as-delivered’ condition which is why such heat treatments should be avoided. It also follows that these steel grades are not suitable for hot-forming. If low-voltage annealing is necessary to compensate for the welding stresses, the recommended annealing time between 530 °C and 580 °C is 30 minutes for all product thicknesses and steel grades.
Welding
These steel grades can be welded both manually and using automatic equipment by means of all electrical welding processes provided the general technical rules are observed. No major hardness increases appear in the heat-affected zone. Preheating is not necessary under normal welding conditions and down to workpiece temperatures of +5 °C. Below +5 °C, pre-heating to 150 °C is recommended.
The welding wires and electrodes approved in the respective strength category must be used as filler metals.
In addition to this, the general meaning of the detailed information provided in ‘Stahl-Eisen-Werkstoffblatt’ (Iron and steel material sheet) 088 must be observed.
Condition of delivery, scope of testing and certificate
The provisions of EN 10149-2 shall apply for delivery and inspection. The products are delivered in a thermomechanically-rolled condition.
