High strength steel is mainly used in offshore engineering, lifting equipment, construction machinery, container storage tank and other important steel structures with harsh working conditions, hoping to reduce weight. The application of LR EH40 wash bulkhead steel, high strength steel can not only reduce material cost, transportation cost and production cost, but also save welding material consumption, welding work hour; reduce post welding stress, preheating temperature and post weld heat treatment requirements.
BEBON cpompany practice new development concepts, expand in an all-round way, deepen reform and innovation, speed up transformation and upgrading, become stronger, better and bigger, accelerate the implementation of BEBON Steel's LR EH40 wash bulkhead steel industrial planning, and realize the revitalization and development of enterprises.Fully implement the corporate LR EH40 wash bulkhead steel market dominant position, comprehensively promote contractual management, and promote the transition from "internal production" to "market operation”.
The preparation of LR EH40 wash bulkhead steel galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for LR EH40 wash bulkhead steel centralized control, two-layer welding process, reducing the possibility of incomplete penetration.
After hot extrusion, the grains of the alloy wear-resistant steel plate are significantly refined, dendrites and network structures are broken, and the grain size and the distribution of precipitated phases in the alloy are more uniform to generate Al2Y and Al3Y phases distributed within and along the grain boundaries , The hardness is significantly improved, the mechanical properties are significantly improved, the deformation strengthening effect is more significant, and the corrosion resistance of the LR EH40 wash bulkhead steel, alloy wear-resistant steel plate is significantly improved.
Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.
