Heat treatment is a very important process to improve the performance of DIN HII pressure vessel steel sheet etc. metal materials. The process of heating, heat preservation and cooling the steel in solid state to obtain the required structure and properties.
Executive Standards of our DIN HII pressure vessel steel sheet, steel plate products: according to the user's requirements, the steel plate can be delivered according to the following standards: national standards, metallurgical industry standards, American ASTM, ASME standards, Japanese JIS, German DIN, British BS, European EN, international ISO standards and relevant standards of special plate. The ship plate can be certified by ABS LR DNV CCS BV KR NK GL RINA.
Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the DIN HII pressure vessel steel sheet steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its DIN HII pressure vessel steel sheet steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.
Welded pipe, also known as welded steel pipe, refers to the steel pipe made of steel plate or strip steel after crimping and forming, with a fixed length of 6 meters. The production process of welded steel pipe is simple, the production efficiency is high, the varieties and specifications are diversified, and the equipment investment is less, but the general strength is lower than that of seamless steel pipe. DIN HII pressure vessel steel sheet, Welded pipes have many uses and are almost ubiquitous in our lives. However, when choosing welded pipes, we must pay attention to performance and material characteristics.
