Welcome to Henan BBN Steel
Laser cutting is that the horizontal laser beam emitted by the laser changes into a vertical downward laser beam through the 45° total reflector, and then focuses through the lens, forming a tiny spot at the focal point. When the spot hits the material, the material is heated to the vaporization temperature quickly, and evaporates to form a hole. With the movement of the beam on the material such as astm a36 s275jr steel, the auxiliary gas (carbon dioxide gas, oxygen, Nitrogen, etc.) blow away the melted slag, make the hole continuously form a very narrow width (such as about 0.1mm) cutting seam, and complete the cutting of materials.
Steel plate numerical control cutting processing, astm a36 s275jr steel steel plate cutting processing can be divided into semi-automatic flame cutting, automatic numerical control cutting, laser cutting, water cutting.The thickness range of steel plate can be cut 20-650mm steel plate, the main steel plate processing material is divided into Q235B plate, Q345B low alloy plate, 45# carbon bond plate.
Q345 is a steel material. It is a low alloy steel, with good comprehensive properties, low temperature properties, cold stamping properties, astm a36 s275jr steel welding properties and machinability. Q345 steel is subdivided into Q345A, Q345B, Q345C, Q345D and Q345E. This is the grade distinction, which represents that the impact temperature is different! Q345A, no impact; Q345B, impact at 20 degrees normal temperature; Q345C, impact at 0 degrees; Q345D, impact at - 20 degrees; Q345E, impact at - 40 degrees. At different impact temperature, the impact value is different.
The company is based on the principle of good faith, small profits and quick sales, and keeps forging ahead. In the fierce market competition, with astm a36 s275jr steel good cooperation and sincere service spirit, we win the trust of our customers and develop rapidly. We will create a win-win situation with our customers and create a better future with the belief of pioneering, pursuing excellence and learning.
