China elongation of api 5l psl2 x56 steel production and operation maintained stable


Plate 20 to 30mm thick elongation of api 5l PSL2 x56 steel product: 20*1400*11400, 20*2100*7000, 20*2500*6200, 20*2933*7300, 20*3200*4400, 20.9*2851*7000, 21*2100*8810, 21.5*1630*13480, 22*3400*13000, 23.1*2590*7790, 25*1950*10150, 25*1950*9700, 25*2100*8400, 25*2100*8650, 25*2400*11600, 25*2400*8200, 28*2170*13000, 30*1600*10720, 30*1600*8600.

It is not the thicker the steel plate is, the better. The larger steel plate thickness means higher price and purchase cost, and it is also not inconvenient for transportation. Besides, the thickness of elongation of api 5l PSL2 x56 steel, steel plate has relation to the safety, so the thickness of steel plate is not determined at random, and the size data of steel plate should be strictly planned according to the requirements of drawings. Therefore, it is necessary to select the appropriate steel plate material and specification according to the use.

It is reported that during the period from the end of 2018 to the first quarter of 2019, some Japanese long process steel mills encountered a series of production line equipment failures, resulting in the overall output decline. Japanese elongation of api 5l PSL2 x56 steel steel mills must give priority to domestic customers, so the export volume in the first half of last year was relatively small. Meanwhile, in the first half of the year, Japan's imports of general elongation of api 5l PSL2 x56 steel steel were about 2.079 million tons, down 16.4% year-on-year; imports of special steel were about 332000 tons, down 14.2% year-on-year.

Only by combining microalloying with controlled rolling and controlled cooling technology can the production of new elongation of api 5l PSL2 x56 steel pipeline steel be perfected.The latter is also known as on-line control of the structure and properties of steels.Recrystallization controlled rolling and conventional controlled rolling are two typical controlled rolling processes, the core of which are high temperature austenite recrystallization, enriched metanucleation in non-recrystallized zone and precipitation enhancement of carbonitride.
