Hot continuous rolling can be divided into ordinary carbon structural steel, low alloy steel and alloy steel according to their different materials and properties. According to the different uses, A514 Gr E high strength steel plate it can be divided into: cold forming steel, structural steel, automobile structural steel, corrosion-resistant structural steel, mechanical structural steel, welding gas cylinder steel and pressure vessel steel, pipeline steel, etc.
Low-alloy high-strength steel grades: Q345B/C/D/E, Q390B/C/D/E, Q420B/C/D/E, Q460B/C/D/E, Q550B/C/D/E, Q690B/C/ D/E, 16MN, A514 Gr E high strength steel plate, A633 Gr A, SA633 Grade C, SA633 Gr.D, SA633 Grade E.Steel plates for bridges: Q235qc, Q235qd, Q345qC, Q345qD, Q345qE, Q370qC, Q370qD, Q370qE, Q420qC, Q420qD, Q420qE.
In line with the service concept of "honesty first, customer first" and the service tenet of "all for customer satisfaction", the company adopts the acceptance and response mode of combining manual and automatic, and accepts the diversified service demands of customer business consultation, complaint declaration, business acceptance, etc. through telephone, fax, e-mail, visit, letter, etc.
After the steel plate is produced from the original factory, it will pass through a series of transportation and storage links and then be delivered to the processing workshop. During this period of time, the steel plate surface will contact with the air continuously, which will inevitably produce a layer of oxide skin. The oxide skin is a difficulty in the treatment process. It has high melting point, is not easy to burn and dissolve, increases preheating time, reduces cutting speed. Therefore, the surface of the A514 Gr E high strength steel plate plate should be derusted before cutting.
