bs EN 10025-6-S690QL biggest 6 mills United Kingdom

The production method of seamless steel pipe can be roughly divided into cross rolling method (menesmann method) and extrusion method. The cross rolling method (menesmann method) is to pierce the tube blank with the cross roll first, and then extend it with the rolling mill. This method is fast in production, but requires high machinability of tube blank. It is mainly suitable for producing carbon steel and low alloy steel tube, bs EN 10025-6-S690QL tube.

Q690D steel belongs to high-strength welded structural steel. Among them, Q represents the yield strength, 690 represents the yield strength value, and D represents the grade of the steel plate. The quality grades of common Q690 series steel are A, B, C, D, E. The impact of grade D steel plate is -20°C. Q690D steel can be called a low temperature resistant high strength steel with a yield strength of 690Mpa.

On the whole, on the one hand, under the support of better macroeconomic expectations and high costs, macro funds have disturbed the futures market from time to time and promoted the phased rise of bs EN 10025-6-S690QL prices. On the other hand, the current steel market's actual demand performance is average, and once bs EN 10025-6-S690QL prices rise too quickly, there will be fear of heights. In the short term, bs EN 10025-6-S690QL prices may fluctuate strongly.
