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 EN S420M steel price, 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.

The company's logistics department has the ability to monitor the whole process of logistics. We monitor the goods in transit through advanced information technology and communication technology, timely discover and handle problems in the transportation process, and ensure the steel materials are delivered to the destination in a timely and safe manner. The professional logistics team provides powerful support for good comments of customers and good reputation of the company.

The selection principle of steel plate for high-rise building is: it can not only make the structure safe and reliable, but also can save steel and reduce the cost. Different use conditions should have different quality requirements. In terms of the mechanical properties of steel such as EN S420M steel price, yield point, tensile strength, elongation, cold bending property, impact toughness etc. are the indicators to measure the quality of steel. In the design of steel structure, the appropriate steel should be selected according to the characteristics of the structure. The selection of steel is not only an economic problem, but also related to the safety and service life of the structure.

Chemical composition of EN S420M steel price, A514 Gr P steel plate (melting analysis %)C: 0.14-0.18 Mn: 1.20 V: 0.03-0.08 Si: 0.10-.040 P: 0.025 S: 0.020 Cr: 1.0-1.5 Mo: 0.4-0.6Mechanical properties of A514 Gr P steel plate:Yield strength≥690MPa, tensile strength≥760-896MPa, elongation %≥16, Akv2 J / longitudinal ≥34, impact temperature - 40℃.
