The nm400 mechanical properties cold brittleness from BBN

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.

Because NM400 mechanical properties, boiler steel plate is a product of important use, the safety and reliability requirements are strict, and the manufacturing technology is difficult. The boiler steel plate material must have the following main characteristics:The boiler steel plate has high yield strength performance in a certain temperature range (medium temperature and high temperature);The boiler steel plate has sufficient toughness, no brittle failure accident will occur during manufacturing or use.

Cold rolled NM400 mechanical properties steel sheet can be produced by two high mill, four high reversing mill, multi high reversing mill and tandem cold mill. Although there are still only two work rolls in four high and multi high rolling mills, each work roll is supported by one or more large diameter backup rolls, which can prevent deflection of work roll. As a result, wide and thinner NM400 mechanical properties steel plates can be produced. For example, 20 high mill can produce as thin as 0. 001 mm sheet, but the two high mill can only produce as thin as 0. 35mm sheet

On August 29th Clients from Senegal visited us-Zhengzhou office and wanted to know more about BBN to build a long relationship. They have a big demand of ship building steel plates with thickness 6mm and thickness 8mm LR AH36 shipping steel NM400 mechanical properties plates to Senegal Navy, and our strong advantage in offering these ship building steel plates make us begin to build a steady cooperation relationship with Senegal clients. BBN has always supplied high quality ship plates with stable supply. Soon he placed 15 containers of LR AH36 shipping steel plates to BBN.
