S355J2 steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the NV A40 passenger container ship steel rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of NV A40 passenger container ship steel steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.
Low carbon alloy steel, the total amount of alloy elements is generally ≦3%; the low carbon alloy steel strength is significantly higher than that of carbon steel, with better plasticity and toughness, and weldability is acceptable; low alloy steel includes carbon manganese series, carbon manganese vanadium series, NV A40 passenger container ship steel chromium molybdenum series, chromium molybdenum vanadium series. Molybdenum and chromium molybdenum vanadium alloy steels are commonly used as materials for hydrogen corrosion resistance, high temperature sulfur or hydrogen sulfide corrosion resistance and heat resistance (sub high temperature).
The company's sales department has a professional team, they have professional steel knowledge, respond quickly, with the problems raised by customers can quickly give solutions, put the interests of customers first. With their own professional knowledge to provide customers with high-quality steel plate in line with the requirements. At the same time, in terms of price, we also have great advantages. Members of the business department make sure that the delivery time is short and the service is the best.

Keep in mind your mission and never forget your mission." At present, the BEBON steel leadership team unites the majority of cadres and employees to keep in mind their glorious missions, guided by Xi Jinping's ideology of socialism with Chinese characteristics in the new era, fully implementing the spirit of the 19th CPC National Congress, in-depth implementation of the requirements of the "three advances", pioneering spirit, and striving In order to lead high-quality development with innovation, build a new pattern of Anshan Iron and Steel's revitalization and development, strive to build the most internationally influential steel company, and make new contributions to the start of a new journey for BEBON Iron and Steel Group.
BBN company is an industry leading steel service center that supplies a full line of hot rolled steel plate in a variety of sizes, grades and finishes. Hot rolled steel is an economical option that offers reliable performance and versatility. In the NV A40 passenger container ship steel hot rolled process, high temperature is used to heat the steel above its recrystallization point. In this state it becomes more malleable, allowing it to be easily formed into a variety of shapes. If you are interested in A36 hot rolled plates price, welcome to come and visit us.
