On 18th December, 2019, BBN Group decorated the office NV A36 dry cargo ship steel building with many kinds of pendant. There were christmas trees, gifts and snowflakes in the logo wall. At the same time, we made a video at the Zhengzhou office to celebrate the coming Christmas holiday. Our NV A36 dry cargo ship steel oversea sales team and market delevopment team wish you Merry Christmas and Happy New Year. Besides, we prepare some meaningful gifts for our old customers.
The impression of most customers who have cooperated with us on the company is being professional and responsible. That mainly owe to our united and considerate team members. For example, the professional technician, the responsible QC inspector, the experienced sales person, the rigorous document maker, the patient after-sales, etc. Their selfless devotion bring the customer good experience, and bring the company good reputation.
In 2018, one of our India customers visit Zhengzhou office building and work shop to discuss carbon steel Q235B grind plate technical request. They have strict surface and thickness tolerance, and they also request UT and MT for testing for Q235B grind plate. As a result, they purchase 179 tons as trial order for first cooperation. After using the gind plate, the India customer has good comment on our NV A36 dry cargo ship steel quality. Till now, we keep exporting around 100 tons per month as regularly.
S355J2 steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the NV A36 dry cargo ship steel rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of NV A36 dry cargo ship steel steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.
When using NV A36 dry cargo ship steel, low-alloy high-strength steel, it is desirable to take advantage of its high strength and use a thinner section, not only for saving weight but also for the economy as much as possible. However, the corrosion factor must be fully considered. The thinner the steel section, the more attention should be paid to corrosion protection. Some low-alloy high-strength steels have good atmospheric corrosion resistance, which can not only improve the effect of anti-corrosion coatings, but in some cases, take appropriate precautions and can even be used without being coated in the atmosphere.
The 2019 Year of the Pig is the 70th anniversary of the founding of the People's Republic of China. Growing up with the motherland, our company sang songs to the mark the 70th victory anniversary. In September, we organized all employees to sing "My Country and I" and made a film.
