Reliable supplier of BP440 bulletproof material

The diameter of large diameter seamless steel pipe is 325mm-1220mm, and the maximum thickness that can be achieved is 200 mm. The diameter of small diameter seamless steel pipe is generally less than 89mm. The processing technology of large diameter seamless steel pipe is hot rolling or hot expanding. There are many materials for large diameter seamless steel pipe, such as BP440 bulletproof material, which can be processed and customized according to customer requirements. The large diameter seamless steel pipe is usually used in the chemical, petroleum, mechanical and other industries.

Shipbuilding steel plates are used to manufacture the hull of marine and inland ships. High strength, plasticity, toughness, cold bending performance, welding performance and corrosion resistance are required for shipbuilding steel plates. Boiler steel plates are used to manufacture various boilers and important accessories. As the boiler steel plate works under medium temperature (below 350℃) and high pressure, it is also subject to impact, fatigue load and water and gas corrosion. The BP440 bulletproof material, boiler steel plate is required to ensure a certain strength and have good welding and cold bending properties.

In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This BP440 bulletproof material production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate BP440 bulletproof material size.

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 BP440 bulletproof material 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.

If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
