S275 material surface quality problems

The company has a group of experienced steel plate continuous processing line construction, production management, operation and professional and technical personnel. The company is a modern enterprise integrating scientific research and development, production processing, sales and service. Our main products include hot rolled plates, seamless pipes, S275 material and steel structures. At the same time, it also adheres to international standards and adheres to the international line.

Because 15CrMo steel contains high content of Cr, C and other alloying elements, the hardening tendency of steel is obvious and the weldability is poor. 15CrMo steel plate is used in petroleum, petrochemical, high-pressure boilers, etc., seamless pipes for special purposes include seamless pipes for boilers, seamless steel pipes for geology, seamless pipes for petroleum, etc. Welcome to contact us for S275 material product price in 2020.

Non-destructive flaw detection of steel plates is a test method for inspecting the S275 material surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used S275 material steel plate flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetration flaw detection, eddy current flaw detection, gamma-ray flaw detection, fluorescent flaw detection, color flaw detection and other methods. Physical flaw detection is non-destructive flaw detection without any chemical changes.

S275 material, Q345R pressure vessel steel is an ordinary low alloy steel, which is commonly used for boiler and pressure vessels. The delivery status of Q345R pressure vessel steel is hot rolling or normalizing. The properties of Q345R pressure vessel steel are similar to those of Q345 steel (16Mn). The yield strength of 16mm steel plate is greater than 345 Mpa, the tensile strength is 510-640 Mpa, the elongation is more than 21%, and the zero degree V-shaped impact energy is greater than 34J. The process reference standard of Q345R pressure vessel steel is GB713.

As a leading international steel supplier, we have two warehouses, close to Tianjin port and Shanghai port. This superior geographical location effectively saves the domestic transportation cost and greatly improves our service level. At the same time, it also shortens our delivery time and provides more convenience for customers.

Our steel products are widely used in petroleum and natural gas, chemical industry, shipbuilding, automobile manufacturing, power generation, mining, and other industries. The products S275 material are sold in more than 20 provinces, cities and all over the world. The company has strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high-quality products.
