S355J2 carbon steel plate sheet, Pressure vessel steel plate is large size steel plate. Pressure vessel steel plate has many special properties, and is widely used in petroleum, chemical industry, power station, boiler and other industries. It is used to make reactor, heat exchanger, separator, spherical tank, oil and gas tank, liquefied gas tank, nuclear reactor pressure shell, boiler drum, liquefied petroleum gas cylinder, high pressure water pipe of hydropower station, spiral case of water turbine and other equipment and components.

Welding is mainly used for manufacturing metal structure parts, and also for manufacturing machine parts. The welding connection performance is good, and it is convenient to weld S355J2 carbon steel plate sheet steel plates, profiles or castings and forgings according to the needs. At the same time, welding can also connect different shapes and sizes (plate thickness, pipe diameter) or even different materials, so as to reduce weight, save materials, optimize resources and other purposes. The welding structure has high rigidity, good integrity, and easy to ensure air tightness and water tightness, so it is especially suitable for S355J2 carbon steel plate sheet manufacturing hollow structures with high strength and large rigidity (such as pressure vessels, pipes, boilers, etc.).

Chemical elements of 35CrMnSi steel: C: 0.32-0.39, Si: 1.10-1.40, Mn: 0.80-1.10, Cr: 1.10-1.40. The mechanical properties of 35CrMnSi steel: tensile strength 1620 MPa; yield strength 1280 MPa; elongation after fracture: 9%; reduction of area: 40; impact energy: 31J. S355J2 carbon steel plate sheet, 35CrMnSi steel is used to manufacture medium speed, heavy load, high strength parts and high strength components, such as aircraft landing gear and high pressure blower blades. 35CrMnSi can partly replace the corresponding CrNi alloy steel in manufacturing small and medium section parts.

As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's S355J2 carbon steel plate sheet steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole S355J2 carbon steel plate sheet steel transportation industry.

our company is a professional ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel exporter and a steel Stockist in china. We keep more than S355J2 carbon steel plate sheet 1000 tons ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel in stock every month.
