Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, astm a633 grade a based on a high starting point and high technology, the company has vigorously developed various steel products astm a633 grade a and deep-processed parts, steel structures, precision castings, seamless pipes.
Steel transportation because of the special material of astm a633 grade a steel, is a metal with "iron" as the main basic element, small volume and large weight, and easy to oxidize and rust when contacting with air and rain water, so there are many precautions in the transportation of steel. There are 11 proverbs for steel transportation: "evenly placed, moisture-proof and rust proof". Our company chooses the logistics aspect to be very rigorous, takes the customer's request as the standard, guarantees the steel product quality.
BBN Group's first blast furnace blast dehumidification system: The project started construction on May 2 and began trial operation on August 28. All data are balanced and stable, blast furnace output indicators have improved significantly, and the daily dehydration capacity of the two blast furnaces is as high as 124 tons, with a daily increase of about 200 tons astm a633 grade a, and the blast furnace is running smoothly.
The Indian customer purchased our A516 Gr 70 pressure vessel steel plates to make tanks. They have very strict requirement for raw materials quality. For the A516 Gr 70 pressure vessel steel plates, they asked for Normalizing, 0℃ impact, A578 UT test, PWHT and so on tests, our Q/C department witness the production process with the technician from the customer company together. Meanwhile, we arrange BV inspection to check the quantity, spray mark, stamp on the A516 Gr 70 pressure vessel steel plates, and so on.
JIS g3101:2004 ss540 structural steel angle contains 0.30% carbon and 1.60% manganese, which greatly improves the strength of steel. Compared with astm a633 grade a SS400 and ss490, ss540 has higher strength with yield strength of 400MPa and tensile strength of 540Mpa. High strength makes it popular in applications that require strength but weight is a problem.
On November 1st, our company organized some of company staff to visit Zhengzhou Children Welfare Institute, and gave children cookies and toys, as well as concerns to the Children.
