What are the precautions during the cutting of S420ML steel channel

BBN company team and culture: tt the end of 2019, in order to thank employees for their hard work and enrich their sparetime lives, the company organized a pleasant trip to Phuket Island, Thailand. This tour lasted 6 days and 5 nights, and returned by plane on the evening of December 27. We took off in Zhengzhou at about 5o'clock in the afternoon on the 22th December. Let's seize the day and live it to the full, and greet the arrival of the year 2020 together.

Compared with S420ML steel channel, pressure vessel and boiler steel plates have such advantages: The pressure vessel and boiler steel should be pure, and the fracture structure of the boiler steel plate should be uniform without cracks and inclusions. Besides, the strain aging sensitivity is small, and the strain aging impact value of the pressure vessel and boiler steel plate is required to be no less than 50% of the non-aging impact value. That is why pressure vessel and boiler steel plate is first choice for fabricating pressure vessels and boilers, while S420ML steel channel is not.

The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the S420ML steel channel principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
