SA573 Grade 65 bulb flat chemical elements

BEBON has been engaged in the piping industry as a professional manufacturer and supplier of steel plates, ship plates, corten steel, pressure vessels, SA573 Grade 65 bulb flat 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, SA573 Grade 65 bulb flat chemical & pharmaceutical pipeline, power plant, sewage treatment, water supply piping, heat exchange application.

In the process of SA573 Grade 65 bulb flat steel transportation, enterprises often use railway transportation, highway transportation, water transportation and other ways to transport. According to the cargo owner's requirements on the timeliness of the goods and the different transportation routes, our company will choose SA573 Grade 65 bulb flat different modes of transportation. According to the specific needs of customers, or specify the mode of transportation.

Try to use SA573 Grade 65 bulb flat high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the SA573 Grade 65 bulb flat temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.

In April 8th, 2018, our Philiphine customer purchased 1008 Tons API 5L Gr.B ERW pipes &Q345B seamless steel pipe for offshore oildfield resources drilling project. This is a regular demand almost every two month, and we has been cooperated more than three times, totally around 2100 tons API 5L Gr.B steel pipeline since 2015 year. We can supply the relative certificated for the API 5L Gr.B ERW pipes products like SGS report, B/L &Form M, and mill test certificate.

40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. SA573 Grade 65 bulb flat, 40Cr alloy chemical composition (C: 0.37 ~ 0.44, Si: 0.17 ~ 0.37, Mn: 0.50 ~ 0.80, Cr: 0.80 ~ 1.10, Ni: ≤0.30, P: ≤0.030, S: ≤0.030, Cu: ≤0.30, Mo: ≤0.10).
