SEW 090-1 Grade S960Q quenched in a liquid medium and tempered introduction
S960Q is a fluid-tempered high strength weldable fine grained steel with a min. yield point of 960 N/mm². It is applicated for high loaded steel constructions, vehicles, lifting, mining equipment. The usual thickness range amounts 3 to 50 mm. The lowest application temperature accounts for -20°C. The steel is processed by cold forming, at temperatures below the highest permissible stress relieving temperature of 530 to 580 °C. After hot forming at 700 to 1050°C has to be coducted a retempering in order to achieve delivery condition qualities. The steel is combustible and electric arc cuttable subject to appropriate mode of operation. Flame cutting is affected by the surface condition. For product thicknesses above 30 mm is advisable a preheating to 100 to 200 °C in order to assure cold crack resistance. Preheating to 100 to 200 °C is advisable for workpiece temperatures below 5 °C and if the thermal cut edges should be cold formed on processing.
