Processing of S690QL High Strength Steel Plate

S690QL Cold Forming

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

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.
