S890 steel is a quenched and tempered high-strength steel plate, the series grades are S890Q, S890QL, S890QL1. S890Q, S890QL, S890QL1 steel,hot rolled RINA DH40 marine plate plates, where S means structural steel, Q means that the impact temperature of the steel plate is -20°C, and QL means that the impact temperature of the steel plate is -50°C. Then guess what QL1 stands for. QL1 means that the impact temperature of the steel plate is -60°C, and 890 means that the thickness is £50mm.
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 hot rolled RINA DH40 marine plate industrial planning, and realize the revitalization and development of enterprises.Fully implement the corporate hot rolled RINA DH40 marine plate market dominant position, comprehensively promote contractual management, and promote the transition from "internal production" to "market operation”.
The blanking of the structural steel plate is first to find 90 degrees, and then use a tape measure and a powder line to draw the cutting range. According to the thickness of the carbon steel plate plus the cutting allowance, drilling is required. For the deep processing of hot rolled RINA DH40 marine plate structural steel sections or profiles: First use a square ruler or a curved ruler to find 90 degrees, and then use a square ruler or a ruler to cut the line and add the cutting margin to the hole.
The effect of alloy elements of hot rolled RINA DH40 marine plate, Q345B alloy steel plate on tempering transformation: improving the tempering stability. The alloying elements delay the decomposition of martensite and the transformation of residual austenite during the tempering process. Increasing the recrystallization temperature of ferrite makes it difficult for carbides to aggregate and grow, so the resistance of steel to temper softening is improved, that is, the tempering stability of steel is improved.
After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
