According to the economic development trend in Asia and the economic development of China, India, Japan and ASEAN, it is estimated that the steel consumption in Asia will be 1228 million tons in 2019, with a year-on-year growth of 6.6%; the NM550 steel price list steel demand in Asia in 2020 is predicted to be 1.241 billion tons, with a year-on-year growth of 1.1%. According to the NM550 steel price list economic development of Europe, it is estimated that the steel consumption in Europe will be 202 million tons in 2019, with a year-on-year decrease of 3.3%; the steel demand in Europe in 2020 is predicted to be 205 million tons, with a year-on-year growth of 1.5%.

Q235NH corrosion-resistant steel plate full name: atmospheric corrosion-resistant hot continuous rolled steel, also known as Corden steel, widely used in: containers, power plants, chimney and railway engineering, such as large outdoor sculpture steel. The corrosion-resistant steel plate (i.e. atmospheric corrosion resistant steel) is a low-alloy steel series with low price and good quality, which is between ordinary steel such as NM550 steel price list and stainless steel. The corrosion-resistant steel can be continuously developed and innovated after being integrated into modern metallurgical new mechanism, new technology and new process. It is one of the series of steel with world advanced super steel technology.

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 NM550 steel price list 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 NM550 steel price list 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.

Expression method of pressure coefficient of seamless steel pipe: pressure P < 7MPa coefficient S-8 7 < NM550 steel price list steel pipe pressure P < 17.5, coefficient 5-6 pressure P > 17.5, coefficient S-4 seamless pipe production and manufacturing: tube blank -- Inspection -- peeling -- Inspection -- Heating -- perforation -- pickling -- grinding -- lubrication and air drying -- welding head -- cold drawing -- solution treatment -- pickling -- pickling and passivation -- Inspection -- cold rolling -- degreasing -- air drying -- internal polishing -- one external polishing -- Inspection -- identification of finished NM550 steel price list product packaging.
