Welcome to BBN High Strength Steels Factory
BBN steel company was founded in 2000, starting the international business in 2010 and successfully being approved and certified by ISO9001:2008. After ten years development, BBN steel has become the large-scale comprehensive enterprise group, combining steel trading, 1.8931 S690Q plate processing, and steel distribution, also have large warehouse and processional representatives both inTianJin, Zhengzhou and Beijing city.
SA387 GR22 CL2 steel plate has the properties of preventing hydrogen embrittlement, hydrogen corrosion, hydrogen peeling, and sulfide corrosion, as well as good low temper embrittlement. It is widely used in the manufacture of fertilizer, petrochemical and thermal power plant equipment. BBNSTEEL has leading production technology, and there are many 1.8931 S690Q products in stock. If you need to fix it, it can be 8mm-120mm-650mm thick and wide to 3900mm.
Grade E, Grade EH32, Grade EH36 series shipbuilding steel products have good comprehensive mechanical properties, welding performance, process performance. Our shipbuilding steel plate and 1.8931 S690Q steel sections are suitable for manufacturing structural parts such as ship hull structures, docks, oil production platforms, marine transmission pipelines, coastal power plants, wharf facilities in ocean, coastal and inland navigation areas.
S355J2 steel plate 1.8931 S690Q 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 rolling speed is 1.6-2.0m/s, the 1.8931 S690Q 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℃.
Mechanical Properties A242 steel:ASTM A242 specification is made for low alloy steel with high strength, it has good atmospheric corrosion resistance, some applications has shown that it has better corrosion resistance than ASTM A36 steel and ASTM A572 Grade 50.Tensile: 70 ksi min (3/4 and under), 67 ksi min (3/4-1.5) 63 ksi min (over 1.5-4)Yield: 50 ksi min (3/4 and under), 46 ksi min (3/4-1.5) 42 ksi min (over 1.5-4)Elongation: 16% min in 8” 19% min in 2” (for plates wider than 24”)
The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
