The BBNSTEEL company has the first-class qualification for steel structure professional contracting, integrating production, design and installation, and can undertake various steel structure projects. The product has a wide surface, flat and smooth surface, and neat trimming. It has users in more than 10 provinces and cities in China and is exported to the United States, Canada, Japan, Europe, Southeast Asia and other countries and regions.
BBN Steel Company adheres to the marketing concept of "first-class technology, first-class steel quality, and first-class logistics services". It is our goal to build high-quality carbon steel A709 grade HPS70W bridge steel plate, alloy steel plates and high-strength structural steel plate international-class boutique bases. Our logistic team will make customs clearance documents, track products production process, and update shipping information for customers. Creating value for customers is our pursuit.
Try to use A709 grade HPS70W bridge steel plate 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 A709 grade HPS70W bridge steel plate temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.
In October, 2018, our Malaysia customer purchased 600 Tons CCS-AH36 Ship Building Steel Plates to use in their shipbuilding project .This customer is a famous shipyard in Malaysia. Their company has the business scope of tourism, A709 grade HPS70W bridge steel plate shipbuilding, transportation and so on. As a terminal manufacturer, they have strict requirements on quality . After visiting our factory, the customer are very satisfied with the quality of this batch of A709 grade HPS70W bridge steel plate CCS-AH36 Ship Building Steel Plates.
35SiMn steel chemical elements: C: 0.32-0.40, Si: 1.10-1.40, Mn: 1.10-1.40. The mechanical properties of 35SiMn steel: tensile strength 885 MPa; yield strength 735 MPa; elongation after fracture: 15; reduction of area: 45; impact energy: 47J. 35SiMn steel belongs to alloy quenched and tempered steel with good properties and can be used instead of 40Cr steel. After quenching and tempering, A709 grade HPS70W bridge steel plate, 35SiMn steel has high static strength, fatigue strength, wear resistance, good toughness, good hardenability and medium plasticity during cold deformation.
We had a wonderful trip in Phuket Island, Thailand. At the end of 2019, in order to thank employees for their hard work for a year and enrich their lives, our company organized a pleasant trip to Phuket Island, Thailand. The tour lasted 6 days and 5 nights, and returned by plane on the evening of December 27. We took off in Zhengzhou at about 5 o'clock in the afternoon on the 22th December.
