S890QL Quenched and Tempered Structural Steel

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.

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.

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.

Welding

S890QL 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 .
