If the wall thickness of the elbow is relatively thick, it is best to perform stress relief heat treatment on the weldment immediately after welding. This is especially true for large-thickness weldments Q235B, high-rigidity structural parts, and weldments that work under severe conditions (dynamic load or impact load). The tempering temperature for stress relief is 600～650℃. For thin-walled elbows, stress heat treatment is not necessary after welding.
What are the characteristics of medium and thick plate, LR DH36 watercraft structural steel? First, the performance of shock resistance and vibration is very good, so the application of medium and thick plates in buildings and bridges can greatly improve the safety. Second, the bearing capacity of medium and thick plate, LR DH36 watercraft structural steel is good, the performance is excellent. The bridge, the automobile girder steel plate, and buildings have strict load-bearing requirements, and it is easy to cause accidents if the steel materials not meet the requirements, so the selection of steel is more stringent.
Last year, the technicians in the automation department of BBN STEEL closely combined the needs of the production line, based on the big data platform. It has successively developed more than 10 industrial software such as intelligent boiler combustion system, equipment full life cycle system, and integration of environmental protection management and control, which provide efficient and intelligent support for comprehensive support of high-end production line production and lays a solid foundation for high-quality development.
