S690QL thickness vs pressure vessel steel plate

S355J2 is a European standard low alloy high strength structural steel grade, equivalent to Q345D. Because of its good impact toughness and welding performance, S355J2 steel plate is widely used in bridges, ships, power plant equipment, hoisting and transportation machinery, machinery manufacturing and other engineering and welding structures that bear high loads. S355J2 steel plate delivery status: hot rolled delivery, the S690QL thickness specific delivery status should be indicated in the contract.

The company mainly supplies S690QL thickness steel materials, and has a large amount of inventory all year round. We can process and cut all kinds of special-shaped steel parts according to your requirements, and we can arrange fresh production for all kinds of S690QL thickness steel materials in customized specifications. The company adheres to the core values of "quality and benefit, integrity and win-win, innovation and efficiency", and provides first-class services. Based on the principle of reputation first, small profits and high sales, we develop the market with high-quality services and flexible business model.

The user of S355NC grade must make sure that his calculation, design and processing methods are appropriate for the S690QL thickness material. The forming process used must be suitable for the intended application and comply with the state-ofthe- art; it is of fundamental importance to the processing behaviour of this S690QL thickness steel grade.

The S690QL thickness, wear resistant steel plate is composed of low carbon steel plate and alloy wear-resistant layer, and the alloy wear-resistant layer is 1/3 ~ 1/2 of the total thickness. The alloy wear-resistant layer and the base plate are metallurgically bonded. When working, the base plate provides comprehensive properties such as strength, toughness and plasticity to resist external forces, and the alloy wear-resistant layer provides wear-resistant properties to meet the requirements of specified working conditions.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
