Low alloy steel ASTM A387 Gr.21 Cl2 boiler plate propety
What are the characteristics of medium and thick plate, ASTM A387 Gr.21 Cl2 boiler plate? First, the performance of shock resistance and vibration is very good, so the application of medium and thick plates in buildings and bridges can greatly improve the safety. Second, the bearing capacity of medium and thick plate, ASTM A387 Gr.21 Cl2 boiler plate is good, the performance is excellent. The bridge, the automobile girder steel plate, and buildings have strict load-bearing requirements, and it is easy to cause accidents if the steel materials not meet the requirements, so the selection of steel is more stringent.
Hot Rolled Plates Products TestingBBN STEEL can supply many tests and analysis done to examine them before and after the manufacturing. As the ASTM A387 Gr.21 Cl2 boiler plate raw material is fetched by us the steel undergoes vacuum treatment, product analysis, additional tensile test, simulated post weld heat treatment, and impact test. After the steel is converted to steel plates they undergo the drop-weight test, hot tensile test, ultrasonic test, the practical examination through examination, and the vacuum carbon deoxidized steel."
The extra thick and extra wide steel plate is one of our superior products (thickness 8mm-650mm, width 1500mm-5200mm, length 3000mm-18800mm). The maximum unit weight is 30 tons. At the same time, we are equipped with large-scale CNC cutting machine, which can cut all kinds of special-shaped parts, flanges and semi-finished products for users, and roll new ASTM A387 Gr.21 Cl2 boiler plate and so on steel products and armor steel for users at any time
Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while ASTM A387 Gr.21 Cl2 boiler plate steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of ASTM A387 Gr.21 Cl2 boiler plate steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.
