EN 10025-6 high strength steel 1.8914 bridge steel plate

Q690D material is a Chinese standard high-strength welded structural steel. What does Q690D stand for? Q represents the yield strength, 690 represents the yield strength value, and D represents the quality of the Q690 steel. The quality grades are A, B, C, D, and E, respectively. The impact of Grade D steel plate is﹣20°C. Q690D executive standard: GB / T1591-2008. EN 10025-6 high strength steel 1.8914, Q690D steel has high yield strength and tensile strength.

The company is a leading steel production and exporting group in steel materials with advanced production technology, metal-cutting skill, and steel structures engineering projects. We can supply carbon steel plate and sheet, alloy steel plates and structural EN 10025-6 high strength steel 1.8914 steel plates. These hot rolled steel plates are sturdy plates having high quality. Their imperviousness to effect and scrapped area, weld capacity, and workability make them a worthy product in a variety of industries.

Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched EN 10025-6 high strength steel 1.8914 increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of EN 10025-6 high strength steel 1.8914 during tempering, while tempering determines the performance and life of the workpiece.

"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, EN 10025-6 high strength steel 1.8914 tube.The extrusion method is to pierce the billet or ingot with a piercer, and then extrude it into a steel tube with an extruder. This method is less efficient than the cross rolling method and is suitable for the production of high-strength alloy steel tubes."
