S890QL is an extra high strength steel to EN10025-6:2004 and the steel number is 1.8983. S890QL has a minimum yield strength of 890Mpa in quenched and tempered conditions, with it’s low temperature of -40 ºC, this steel grade perform good durability in extreme working environments.

S890QL extra high strength structural steel plate is an ideal leaner weight for your project as it has 224% more higher strength than S275JR structural steel, it is relatively easy welding and fabricate. It has becoming more and more popular in crane, oil and gas, mining, earthmoving, agricultural, trailers, theme park, bridge building, extreme weather search and rescue industries and modern super structural design where light weight and leaner thickness steel plate with increase payload capacity. Today, beautiful high-rice buildings and super architectural design art has became reality because of the discovery of S890QL steel plate.

Other steel product for 890Mpa extra high yield strength such as seamless tube in rectangular, square, circular, elliptical, half-elliptical, flat-oval, octagonal, hexagonal and triangular are available in Beverly Steel Malaysia, please contact our sales team for further information.
