Q345NQR2 tempered steel chemical composition

The main steel plates for oil and gas pipelines are X42, X46, X52 (L360), X56 (L390), X60 (L420), X65 (L460), X70, X80. The specification range of steel plate used by the company for oil and gas pipelines: thickness 8mm-60mm. It can produce additional flaw detection requirements and Z15-Z35 tear resistance (thickness direction performance) steel plates Q345NQR2 tempered steel, and can also provide Z-direction performance steel plates according to ASTM A770 and other standards.The company covers an area of 15,000 square meters and the plant construction area is 10,000 square meters. We have introduced more than 50 sets of advanced Q345NQR2 tempered steel production equipment, auxiliary equipment and testing equipment at home and abroad, more than 260 employees, more than 20 middle and senior management staff, more than 10 professional and technical personnel, annual production capacity of 100,000 tons. Main products: flat steel, Q345NQR2 tempered steel steel pipe, steel plate, section steel, steel structure processing parts, etc. We also accept incoming materials and annealing processing.The blanking of the structural steel plate is first to find 90 degrees, and then use a tape measure and a powder line to draw the cutting range. According to the thickness of the carbon steel plate plus the cutting allowance, drilling is required. For the deep processing of Q345NQR2 tempered steel structural steel sections or profiles: First use a square ruler or a curved ruler to find 90 degrees, and then use a square ruler or a ruler to cut the line and add the cutting margin to the hole.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 Q345NQR2 tempered 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.After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
