What is S890ql1 Steel Plate ?
S890QL1 is a high-strength, fine-grained structural steel (EN 10025-6) that is quenched and tempered, known for its exceptional yield strength of 890 MPa and good toughness, even at low temperatures (down to -60°C). It's used for heavy-duty applications like construction, vehicles, and mining equipment where load-bearing capacity and durability are crucial, offering good weldability and formability despite its strength.
S890QL1 is a fluid-tempered high strength weldable fine grained steel with a min. yield point of 890 N/mm². It is applicated for high loaded steel constructions, vehicles, lifting, mining equipment. The usual thickness range amounts 3 to 100 mm. The lowest application temperature accounts for -60°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. Instructions: The steel is suitability tested for the construction of pressure vessels and pressure pipes.
