A few days ago, the Korea iron and Steel Association said that in February, the stock of cold rolled steel plates in South Korea reached 97 thousand and 400 tons, a decrease of 3.5% compared with the same period, an increase of 25.1% over the same period last year. Generally speaking, the beginning of spring production will lead to the decline of stainless steel stock, but the sales of stainless steel in South Korea will keep warm. The stainless steel production in Korea is expected to be 90 thousand tons ~10 million tons. Therefore, the growth of stainless steel consumption in Korea is basically stagnant. South Korea's stainless steel cold-rolled plate producers and distributors are puzzled.

In March 26th, the latest data from the World Steel Association showed that India has become the world's second largest producer of coarse steel, with 8 million 430 thousand tons of crude steel in February 2018 and 8 million 300 thousand tons in Japan. In the first 2 months of 2018, the crude steel output in India was 17 million 462 thousand tons, up 2.9% compared to the same period last year, and the crude steel output in Japan was 17 million 321 thousand tons, down 0.1% compared with the same period last year.

In March 23rd, the American steel Society (AISI) report showed that the United States imported 2 million 363 thousand short tons of crude steel in February this year, including 1 million 923 thousand short tons of finished products (18% and 17.6% respectively). The import of crude steel and finished products in the United States were 5 million 245 thousand short tons and 4 million 257 thousand short tons respectively in the first 2 months of this year, down 5.3% and 3.5% respectively over the same period of last year. According to the report, it is estimated that imports of finished products accounted for 24% of the US market share in February this year, and the US market share of imported products accounted for 25% in the first 2 months. The total imports of crude steel and finished products will be 31 million 500 thousand short tons and 25 million 500 thousand short tons in 2018, down 17.5% and 13.6%, respectively. In February this year, the main export products of the US increased significantly, including steel structure profiles (growth of 60%) and wire rod (37%). In the first 2 months, the major products of US imports increased substantially from the same year to year, including hot rolled coils (33%), pipeline (30%) and hot rolled steel (up 27%).

The Wall Street Journal reported in a report on the 16 day of the Wall Street. Peter, director of the White House National Trade Commission, is closely related to the interests of the US iron and steel industry. He has instructed the Steel Corp to provide funds for filming documentary supporting his political views.

According to Indonesia, "Jakarta post" reported on February 8th, the Indonesian iron and Steel Association released data show that in 2017 Indonesia imported 6 million 430 thousand tons of steel, accounting for 48% of the total annual steel consumption in 2015 and 2016, respectively; Indonesia imported steel 6 million 850 thousand tons and 6 million 490 thousand tons, is the world's five largest importer of iron and steel.

According to researchers, this dense wood can block bullets. In this study, stainless steel balls fired by air guns easily penetrated ordinary wood but did not penetrate the same thickness of treated wood. The team said that this technology may bring a new kind of strong, lightweight wood material. This material can be used to replace steel in construction, to make lighter and better performing vehicles, and even to make bulletproof armor.

US media claimed that South Korea mentioned its role in the situation on the peninsula. Europe reminds the United States that it is actually a long-term military ally of the United States. Australia has used secret weapons: President Trump's good friend and legendary golfer Greg Norman. Just one day after Trump signed an order to impose tariffs on imported steel and aluminum, the manufacturing nations began to work hard to enter the list of exempted countries for these tariffs, including persuasion, threats, personal charisma and diplomatic influence. According to the report of the “New York Times” website on March 9th, while EU leaders listed the list of US products levied on retaliatory tariffs and threatened to sue the WTO, they also reviewed the long history of friendly relations between Europe and the United States. German Minister of Economic Affairs Brigitte Teplice wrote to US Secretary of Commerce Wilbur Rose. She said that Europe and the United States should work together to solve the real problem: the global steel production capacity that led to the price drop. She said: "On this issue, Europe and the United States need unity and no trade conflicts can occur."

In January 26, 2018, the United States cispi (Cast Iron Soil Pipe Institute) on behalf of the domestic industry in the United States to the United States Department of Commerce and the U.S. International Trade Commission (USITC) submitted to the Chinese iron water pipe (Cast Iron Soil Pipe) anti-dumping and countervailing investigation application. At present, the U. S. International Trade Commission's industrial damage investigation procedure has been launched, and the US Commerce Department will decide whether to file a case within 20 days.

As an important part of seamless steel pipe, steel pipe plays an important role in the development of national economy. The general trend of development of the steel industry in the world is: welded steel pipe production growth faster than the growth rate of seamless steel pipe; welded steel pipe production is far greater than the proportion of seamless steel pipe; for seamless pipe market in various areas; hot dip galvanized pipe in welding steel pipe welded steel pipe type, ERW is dominant in the production but, in the use of field pipelines, oil and gas pipelines in city gas pipeline within the longitudinal submerged arc welded pipe and spiral submerged arc welded pipe for the market.

ERW pipe's application includes three aspects, first, for low pressure fluid transmission, such as water pipelines, agriculture & irrigation (water mains, sewerage systems, industrial water lines,; ant piping, deep tube-wells & casing); second, for machinery manufacturing, such as engineering purpose, fencing, scaffolding, line pipes etc .; third, for Gas pipe lines (pipe lines for natural gas), LPG and other non-toxic gas.

With the continuous structural reform of the supply side, the steel industry related metal products industry, including the steel pipe industry, has been brewing a good trend recently, but the real turning point of the relevant industries has not yet come. According to statistics, after nearly a decade of development, China's steel pipe industry has been continuously optimized and upgraded in terms of product structure, quality level, technical equipment and so on. It has become a veritable world steel pipe manufacturing powerhouse and is now making its stride in the world's steel pipe industry. However, the staged contradictions and structural contradictions in the development of China's steel pipe industry have emerged as a "bottleneck" that hinders the sustainable, healthy and stable development of the steel pipe industry. The depth adjustment of the steel pipe industry is still under way.
