Surface heat treatment methods for 09CuPCrNi-B grade steel

SA516 70 grade has the highest tensile and yield strength range due to the highest carbon content (up to 0.28%). For high-grade 09CUPCRNI-B grade steel steel plates such as SA516 70 grade, especially thick steel plates need to be preheated during arc welding.

The clad steel plate is based on carbon structural steel, which is sprayed with stainless acid resistant and heat-resistant steel on the surface. The clad steel plate is widely used to make acid and alkali resistant container. Advantages of clad steel plate: The appearance of the clad steel plate is very smooth, the quality is very good, and it will not rust. Disadvantages of clad steel plate: the 09CUPCRNI-B grade steel, clad steel plate has better requirements for production technology and are more expensive.

Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process. They need to be heated to 1100 ° C to 1250 ° C for rolling. This 09CUPCRNI-B grade steel rolling process is called hot rolling. Rolling at room temperature is generally understood as cold rolling. However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling.

Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our 09CUPCRNI-B grade steel products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.
