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.

Our company can produce A573 Gr 70 structural carbon steel sheet, EN10025-2 S355J2 structural steel plates and sheets up to 400mm thickness. S355J2 steel consists of S ( for structural steel), 355 (indicates the minimum specified yield strength value in MPa for thickness less than 16mm), J2( for a minimum impact energy value of 27J at -20ºC). EN S355J2 structural steel plates are suitable for cold flanging, delivery condition normalized rolled or as rolled.

Our company produces ordinary carbon steel A573 Gr 70 structural carbon steel sheet with high strength and good plasticity and toughness. Due to the effect of alloy elements, its strength is 25% - 50% higher than that of ordinary carbon steel, its elongation is 15% - 23%, and its impact toughness at room temperature is higher than 60j / cm 2. We have a A573 Gr 70 structural carbon steel sheet production line specializing in the production of ordinary carbon steel plate, and strictly control its quality.

The effect of nitrogen (N) on the properties of A573 Gr 70 structural carbon steel sheet and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in A573 Gr 70 structural carbon steel sheet and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.

Boiler steel A573 Gr 70 structural carbon steel sheet inventory: 14*2000*11181, 14*2070*9060, 14*2200*10030, 15*2200*10270, 15*2500*10000, 15*2992*10185, 16*1500*9340, 16*1800*6000, 16*2000*10713, 16*2120*6080, 16*2230*7650, 18.5*2320*6600, 20*1400*11400, 20*2100*7000, 20*2933*7300, 20*3200*4400, 20.9*2851*7000, 21*2100*8810, 21.5*1630*13480.

The steel plate, steel pipe and other steel materials are the important material in the material engineers. Our company will provide the high quality the steel plate, steel pipe and other steel materials for you. We are exported the steel plate, steel pipe and other A573 Gr 70 structural carbon steel sheet steel materials to the customers from USA, South America, Europe, Africa etc. If we can have the good cooperation together, you will be very welcome to be our agent in your local market. Let’s work together!

We have a professional after-sales service team, the company has developed a clear service process and service standards, after-sales service team members strictly perform after-sales procedures, comply with service standards.
