Nickel element is mainly used to form and stabilize the austenite structure, so that the A514 Gr B alloy steel plate steel has good mechanical properties, corrosion resistance and process performance. Molybdenum can quickly passivate stainless acid-resistant steel, and improve the corrosion resistance to solutions containing chloride ions and other non-oxidizing media. Titanium and niobium are usually used to fix the carbon in alloy steel and make it generate stable carbides to reduce the harmful effect of carbon on the corrosion resistance of alloy steel.
In the first quarter of 2020, the output of EU steel pipe industry decreased by 13.3% year-on-year, but it is considered to be flexible due to its close connection with the A514 Gr B alloy steel plate construction industry. However, demand for large welded pipes is expected to remain weak in the oil and gas industry. In 2020, the steel consumption of steel pipe industry will account for 13% of EU A514 Gr B alloy steel plate steel consumption market. Uestf predicts that in 2020, the output of steel pipe industry will continue the downward trend of 2019, with a year-on-year decrease of 19.4%, and a rebound of 9.8% in 2021.
