What are the S690QL material number advantages

StE 480.7 TM steel plate/pipes,under DIN 17172 standard, we can regard StE 480.7 TM steel plate/pipes as large diameter pipes. S690QL material number, StE 480.7 TM steel plate/pipes is one mainly of Steel for large diameter pipes,DIN 17172 StE 480.7 TM steel with the demands in mechanical properties of the pipes followed the DIN 17172 specification for grade StE 480.7 TM(YS is 485MPa, TS is from 600-750 MPa).It is well known that a low carbon bainitic microstructure offers an excellent combination of strength and toughness.

In order to further promote the ultra-low emission process and the technological innovation of flue gas treatment technology in China's steel industry, the China Institute of Metals and Beijing China-Japan Energy Conservation and Environmental Protection Engineering Technology Co., Ltd. (hereinafter referred to as Beijing China-Japan Alliance) will carry out technical cooperation to promote the activated coke dry process The application of desulfurization and denitrification technology in iron and steel enterprises, the signing ceremony of technical cooperation between the two parties was successfully held recently at the Chinese Institute of Metals.

The large diameter cold drawn seamless steel pipe is a steel pipe with an outer diameter of more than 1000mm. The large diameter seamless steel pipe is made of steel ingot or solid billet through perforation and then hot rolling, cold rolling or cold drawing. If they are long, they need to remove the redundant parts, that is, cut them out. Their length S690QL material number is suitable for the length required by the construction of steel pipes.

The company has strict control on the quality of S690QL material number. Each S690QL material number 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 material number meets the specified quality requirements.
