Hot rolled S690QL steel material production mechanical properties

BEBON has been engaged in the piping industry as a professional manufacturer and supplier of steel plates, ship plates, corten steel, pressure vessels, S690QL steel material production steel pipelines, seamless pipe and ERW pipes since the inception. We provide integrated solutions to whole-package procurement covering miscellaneous ferrous and non-ferrous piping components. The products are widely used in oil & gas project, subsea or offshore platform piping, S690QL steel material production chemical & pharmaceutical pipeline, power plant, sewage treatment, water supply piping, heat exchange application.

Low welding crack sensitivity high-strength steel plate, today mainly introduces Q620CF, with three grades C, D, E. The grades of low-welding crack sensitivity high-strength steel plate: Q460CFC, Q460CFD, Q460CFE, Q500CFC, Q500CFD, Q500CFE, Q550CFC, Q550CFD , Q550CFE, Q620CFC, Q620CFD, Q620CFE, Q690CFC, Q690CFD, Q690CFE, S690QL steel material production, Q800CFE. It is mainly used for the production of hydropower penstocks, construction machinery, railway vehicles, bridges, high-rise and large-span buildings that require high weldability.

The boiler steel pipe has excellent anti-oxidation and corrosion performance: the general steel pipe is easy to be corroded under high temperature and produces harmful substances, but the boiler steel pipe has no such worries. The high-precision material and wall thickness of the boiler steel pipe can effectively prevent the corrosion. Good tensile strength of S690QL steel material production, boiler steel pipe: it can keep the original state well without affecting its quality after being heated and stretched.

Now many manufacturers will use CNC equipment to complete the steel plate cutting processing, this processing method is also gradually increasing, but if you want to make the processing effect meet the specifications and standards, the control requirements of operation technology are also relatively high. Now there are many kinds of steel plate cutting, during the actual processing, it is necessary to select the appropriate processing method according to the cutting requirements of steel plate, so as to achieve the ideal processing effect for S690QL steel material production.

According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for S690QL steel material production, 42CrMo steel is quenching and tempering.

Our company will accept the product quality objection registration record, pass it to the S690QL steel material production production unit and relevant departments, and timely coordinate the supervision of product S690QL steel material production quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
