What is the price of B480GNQR weathering steel, low alloy steel plate? The low alloy steel plate quality of different manufacturers is different. Generally speaking, the quality of B480GNQR weathering steel, low alloy steel plate produced by famous manufacturers will be better guaranteed, and the price is also relatively expensive. Besides, it is related to the grade of low alloy steel plate. The better the performance, the higher the price. In addition, it is related to the specification of B480GNQR weathering steel, low alloy steel plate. And the price of different size and thickness plate is different. Finally, we can learn more information about B480GNQR weathering steel, low alloy steel plate price through the comparison of multiple manufacturers or through the Internet.

Ordinary carbon structural steel B480GNQR weathering steel has many impurities and low price. The ordinary carbon structural steel is used in places with low performance requirements and low strength, but it has good plasticity, toughness and cold deformation performance. High quality carbon structural steel has less harmful impurities, and its strength, plasticity and toughness are better than those of ordinary carbon structural steel. High quality carbon structural steel is mainly used to manufacture important mechanical parts.

Composition characteristics of low alloy structural steel, B480GNQR weathering steel: (1) Low carbon: the carbon content of low alloy structural steel is less than 0.20% due to the high requirements of toughness, weldability and cold formability. (2) The alloy elements such as manganese are added. (3) The addition of Nb, Ti or V and other auxiliary elements: a small amount of Nb, Ti or V forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of low alloy structural steel. In addition, adding a small amount of copper (≤ 0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. The addition of a small amount of rare earth elements can remove sulfur and gas, purify the steel, and improve the toughness and process performance of low alloy structural steel.

S355J2 steel plate belongs to European standard low alloy steel, the executive standard is EN10025-2. Delivery status: normalizing, hot rolling or control rolling. S355J2 corresponds to the Chinese Q345D, but the executive standard is different, the chemical composition is slightly different, but their mechanical properties are the same. S355J2 low alloy steel plate tensile strength (MPA): 450-680, impact value: - 20 ℃: ≥ 27J. B480GNQR weathering steel, S355J2 low alloy steel plate is widely used in bridges, vehicles, ships, buildings, steel structures, etc.
