Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional bs EN 10025 S690QL production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of bs EN 10025 S690QL leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.

The carbon and low alloy steel plates are our main products. Our main conducted standards for carbon and low alloy steel plates are (ASME) ASTM (S)A36, (S)A283, bs EN 10025 S690QL, (S)A572, (S)A573, (S)A633, (S)A709, EN10025-2, EN10025-3, EN10025-4, EN10025-6, JIS G3101, JIS G3106, DIN 17100, DIN 17102, etc. Our typical carbon and low alloy steel grades are (S)A36, (S)A283 grade C, (S)A572 grade 50, S235JR, S355JR, S355J2, SS400, SM570, ST37-2, ST52-3, Q235B, bs EN 10025 S690QL, Q345B, etc.

09CuPCrNi-A steel is weather resistant steel. It is also called 09CuPCrNi-A weathering steel, or 09CuPCrNi-A anti-corrosion steel. 09CuPCrNi-A steel is equivalent to SPA-H, Corten B, etc. steels. Compared with those steels, 09CuPCrNi-A steel price is cheaper while the performance is similiar. That is mainly because the demands for 09CuPCrNi-A steel is very large in China, which is one of the largest steel prodction and export country. So the production capacity of 09CuPCrNi-A steel in very large in China. Consequently, the unit cost of 09CuPCrNi-A steel is cheaper.

Preheating cutting: The most effective way to prevent steel plate cutting cracks is to preheat before cutting. Before flame cutting, the steel plate is usually preheated, and the preheating temperature mainly depends on the quality level and thickness of the steel plate. The preheating method can be carried out with flame burner, electronic heating pad, or heating furnace. In order to determine the preheating effect of the steel plate, the required temperature should be tested at the heating point.

The proportion of main elements in Q345 steel is basically the same as that in 16Mn steel, the difference is that V, Ti, Nb microalloy elements are added. A small amount of V, Ti, Nb alloy elements can refine the grains, greatly improve the toughness of the steel, and greatly improve the comprehensive mechanical properties of the steel. Because of this, the thickness of bs EN 10025 S690QL, Q345 steel plate can be made larger. Therefore, the comprehensive mechanical properties of Q345 steel should be better than that of 16Mn steel, especially its low temperature properties. The allowable stress of Q345 steel is slightly higher than that of 16Mn steel.
