S460ML equivalent grade seamless pipe belongs to high strength medium carbon steel, with certain plasticity and toughness, high strength and good machinability. Good comprehensive mechanical properties can be obtained by quenching and tempering treatment. In addition, the hardenability of 45# seamless pipe is poor, and the water quenching is easy to produce cracks. After quenching and tempering, the small and medium-sized parts can obtain better toughness and higher hardness. For large parts (the section size is more than 80mm), normalizing treatment is appropriate. But the weldability of No.45 steel is poor. The weldment should be preheated before welding and annealed after welding to eliminate welding stress.
The Alacero (Latin American Iron and Steel Association) predicts that the S460ML equivalent grade and so on steel consumption in Latin America will reach 66 million tons in 2020, a year-on-year increase of 2.8%. The forecast is influenced by Brazil, the major economy in the region. With the implementation of economic reform measures, the outlook for the Brazilian economy is positive. Our steel business has been occupying a large share in the Latin American market, keeps an increasing trend in recent years, and has won the trust of customers in local. This year we must seize the opportunity to make greater contributions to the local development.
The steel market is full of good and bad, and the quotation is chaotic. The price of S460ML equivalent grade, spiral welded pipe is fluctuating. It is better to understand the market price of spiral welded pipe before purchasing. If it is a large project, the required quantity of spiral welded pipe is large, the price selection should be particularly careful, and we can select several suppliers for comparison. In addition, we shall not only consider the price, but also put an eye on the quality, the actual weight.
Novel coronavirus pneumonia has been closed in recent years, and Pohang iron and Steel Co., Ltd. closed its overseas processing center in Italy, Malaysia, Philippines and India. At the request of the Italian government, all production activities will be stopped except for the necessary S460ML equivalent grade products. POSCO-ITPC, an Italian stainless steel cold rolling mill near Verona in northeast Italy, is scheduled to close from March 26 to April 3.
