Principle of surface pretreatment of material S960Q

With high-quality material S960Q steel and professional services, we have won international praise in infrastructure, shipbuilding, oil and other industries, and gradually grow into a bright star in the steel export industry, while winning unanimous praise from foreign customers. It has laid a foundation for the development of our material S960Q steel market and improved the control of steel plate production quality.

The common uses of material S960Q, boiler and pressure vessel steel plate are as follows. First, make boilers and pressure vessels. Boiler and pressure vessel steel plate not only has a certain strength, but also has a certain ability to withstand impact. The boiler and pressure vessel steel plate should be resistant to abrasion and high temperature. Second, the boiler and pressure vessel steel plate is used to make spherical tank, oil gas tank, liquefied gas tank and other tanks. The boiler and pressure vessel steel plate should have the characteristics of corrosion resistance and pressure resistance.

As a new type of coil material, compared with the traditional steel coil, material S960Q, the alloy steel coil and sheet has a great improvement in performance properties. The alloy steel coil and sheet has good thermal strength and oxidation resistance at high temperature. Moreover, the corrosion resistance of alloy steel coil and sheet is better. After long-term corrosion, the service life of traditional coil plate will decrease rapidly, but the new type coil, the alloy steel coil and sheet has strong corrosion resistance, and its service life is far longer than that of traditional coil plate.

Generally speaking, rolled plates are easier to handle in a high temperature environment, and the heat treatment of material S960Q, rolled plates is also very common. Hot rolling can not only greatly reduce energy consumption and save costs, but also improve the processing performance of metals and alloys, that is, the coarse grains in the as-cast state are broken, the cracks are healed significantly, and the processing performance of the alloy is improved.

material S960Q, Q345 and Q345B are steel numbers. The differences are as follows:1. Q345 is general and does not indicate the quality level; Q345B is clear and the quality level is B.2. Q345 does not require to inspect the impact performance; Q345B requires that the impact performance at room temperature is qualified (impact at 20 ℃).3. Q345 does not indicate carbon content of steel; Q345B carbon content is 0.20%.Q345 refers to carbon structural steel with yield point (σ s) of 345MPa. The following letters indicate the quality level, including A, B, C, D and E.

The company has sufficient stocks and complete specifications. The common carbon steel plates, marine plates, material S960Q and storage tank steel plates sold are all produced by large state-owned steel companies such as Shougang, Hegang, Taiyuan Iron and Steel, with quality assurance and worry-free after-sales. The company develops and grows under the concept of seeking innovation in stability and advancing with the times for development. After a short period of development, it has begun to take shape.

The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
