Application areas | Quend 900 is recommended for the following applications: | |
Chemical composition | The steel is fine grain treated. | |
Cold Forming | Quend 900 is very well suited for cold forming operations. Quend 900 complies with the S890QL bending requirements but offer even closer R/t ratios: *R = Recommended punch radius (mm), t = Plate thickness (mm) , W – Die opening width (mm) (bending angle ≤ 90°) | |
Delivery condtion | Quend 900 is delivered as quenched and tempered. Our Quend plates are supplied as standard in the shotblasted and painted condition. In order to maintain a good weldability and laser cutting performance, a low zinc silicate primer is applied. Plates can also be delivered unpainted. | |
Heat Treatment | The mechanical properties of Quend 900 has been obtained by quenching and tempering. For not losing the guaranteed properties of Quend 900, the plate should not be used in applications requiring hot working and service temperatures above 550 °C. | |
Machining | Quend 900 provides a very good machinability and can be drilled, counter sinked and milled in the same way as any other 900MPa or S890QL Q&T steel. | |
Other | Quend 900 is delivered with a unique combination of excellent flatness, tight thickness tolerances and superior surface finish. | |
Testings | Ultra sonic testing (UT), is applied to secure the plate from discontinuities like inclusions, cracks and porosity. In thickness from 8 mm and up, all plates are UT tested and controlled against class S2, E2, according to EN 10160. | |
Thermal cutting and welding | Quend 900 may be cut either by oxygen fuel, plasma and laser cutting without any restrictions. Subsequent to cutting, let the cut parts slowly cool down to room temperature. Do never accelerate the cooling of the parts. A slow cooling rate will reduce the risk of cut edge cracking. | |
Welding | Welding of Quend 900 can be performed using any of the conventional welding methods available both as manual or automatic. In the thickness range up to 10 mm, preheating prior to welding is normally not needed, if a heat input of 1,7 kJ/mm is used. Welding of Quend 900 is recommended to be performed at ambient temperature not lower than +5 °C. Subsequent to welding, let the welded parts slowly cool down to room temperature. Do never accelerate the cooling process of the weld. It is always recommended to use low hydrogen electrodes when welding Quend 900. |
