Cutting method of EN 10025 S620QL high strength steel

Every after-sales service shall have a detailed record of the customer's product problems and handling methods. The records shall be sorted into volumes and filed on a monthly basis, and submitted to the technical department for filing. The problems found in the after-sales service shall be summarized in a timely manner, discussed with the technical department, the quality inspection department and the production department, and a proper solution shall be proposed for the technical department to improve in a timely manner;

15crmo alloy pipe is a kind of seamless steel pipe, and its performance is much higher than ordinary seamless steel pipe. Because this kind of steel pipe contains more Cr, its high temperature resistance and corrosion resistance are not comparable to other seamless steel pipes, so alloy pipes are widely used in petroleum, chemical, electric power, boiler and other industries.

The heat treatment process can significantly improve the physical properties of steel, improve the compressive strength, ductility and service life of parts, and improve the hardness and wear resistance. Therefore, critical equipment parts and special tools must be quenched and tempered. The quenching and tempering treatment can also improve the production and processing performance of the EN 10025 S620QL high strength steel product workpiece, thereby improving the production efficiency and production processing quality.

S355J2G3 is low alloy high strength structural steel, and it is roughly equivalent to GB Q345D.S355J2G3 is a European standard steel with composition of C ≤ 0.20, Si ≤ 0.55, Mn ≤ 1.60, P ≤ 0.035, S ≤ 0.035. The meaning of J2G3 indicates that the delivery state of S355J2G3 steel is normalized, the impact energy at - 20 ℃ is 27J. G3 and G4 indicate the deoxidization mode. EN 10025 S620QL high strength steel, S355J2G3 steel is semi killed steel, S355J2G4 steel is fully killed steel.
