Processing of S690QL High Strength Steel Plate

S690QL Cold Forming

S690QL steel plate is suitable for cold-forming adhering to a bending or folding radius > 4 times steel plate thickness longitudinal and > 3 times transverse to rolling direction. A subsequent stress relief annealing is possible up to a temperature of 580 ºC (degree C).

Minimum recommended inside bending radius
Axis of bend in transverse direction 3.0t	Axis of bend in longitudinal direction 4.0t

S690QL Hot-Forming

Hot-forming above 580°C is possible. A subsequent quenching and tempering has to be carried out according to the conditions of delivery.

S690QL Milling

Drilling with cobalt-alloyed high-speed steels HSSCO. Cutting speed should be approximately 17 - 19 m/min. If HSS drills are used, cutting speed should be approximately 3 – 5 m/min.

S690QL High Strength Quenched and Tempered Structural Steel

S690QL Flame-Cutting

The temperature of the material should be at least RT for flame-cutting. In addition, the following

preheating temperatures are recommended for certain plate thicknesses: For plate thicknesses over 40mm, preheat to 100°C and for thicknesses over 80mm, preheat to 150°C.

S690QL Welding

S690QL steel is suitable for all current welding methods. The temperature of the material should be at least RT for welding. In addition, the following preheating temperatures are recommended for certain plate thicknesses:

20mm – 40mm: 75°C

Over 40mm: 100°C

60mm and over: 150°C

These indications are standard values only, in principle, indications of SEW 088 should be adhered to.

The t 8/5 times should be between 5 and 25 s, depending on the welding technique used. Should stress relief annealing be necessary for constructional reasons, this should be done in the temperature range of 530°C-580°C
