S690QL bending Sheet Price

The company has strict control on the quality of S690QL bending. Each S690QL bending is inspected for the whole process, including raw material purchase, production process according to the procedures and relevant regulations. According to the technical standards and technical requirements, the composite quality inspection is carried out to confirm whether the S690QL bending meets the specified quality requirements. If the S690QL bending does not meet the quality requirements, the non conformity control shall be implemented, and the unqualified S690QL bending shall be removed, marked, registered and effectively isolated; the S690QL bending shall be inspected and confirmed for acceptance, release and delivery, and the quality certificate shall be issued.

Heat treatment process: heat treatment refers to a kind of process operation in which the metal or alloy can change the internal structure through certain heating, heat preservation and cooling methods in the solid range to obtain the required performance. S690QL bending Heat treatment process refers to the ability to change the microstructure and properties of S690QL bending after heat treatment, including hardenability, hardenability, temper brittleness, etc.

Molybdenum is a well known alloy element. Molybdenum can refine the grains of steel material, improve the hardenability and thermal strength, and maintain sufficient strength and creep resistance at high temperature. Adding molybdenum to S690QL bending, structural steel can improve mechanical properties. Molybdenum can also restrain the brittleness of alloy steel caused by quenching treatment.

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
