Under normal exposure to the atmosphere, A283 Gr C CS steel carbon plate, bare steel forms a tight protective oxide film during the first few months of atmospheric corrosion. Sometimes architects choose bare steel structures because they want to get the appearance of uniform atmospheric oxidation on the steel surface, and sometimes they are to save the protective coating for economic purposes. To use these low-alloy high-strength steels in a bare state, the design must consider that the surface of the steel cannot be wet for a long time, and special attention should be paid to the special atmospheric environment to ensure that the corrosion rate of the steel is allowed under this condition.
The proportion of main elements in Q345 steel is basically the same as that in 16Mn steel, the difference is that V, Ti, Nb microalloy elements are added. A small amount of V, Ti, Nb alloy elements can refine the grains, greatly improve the toughness of the steel, and greatly improve the comprehensive mechanical properties of the steel. Because of this, the thickness of A283 Gr C CS steel carbon plate, Q345 steel plate can be made larger. Therefore, the comprehensive mechanical properties of Q345 steel should be better than that of 16Mn steel, especially its low temperature properties. The allowable stress of Q345 steel is slightly higher than that of 16Mn steel.
Flat steel is a kind of steel with rectangular cross-section and blunt edges at the edges and corners. It is usually 12-300 mm wide and 3-60 mm thick. Compared with A283 Gr C CS steel carbon plate ordinary steel plate, the utilization rate of flat steel is increased by one to five percentage points. Moreover, flat steel can be produced with fixed thickness, width and length according to the user's requirements, which saves the cutting process for users, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and material.
Our company will accept the product quality objection registration record, pass it to the A283 Gr C CS steel carbon plate production unit and relevant departments, and timely coordinate the supervision of product A283 Gr C CS steel carbon plate quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
BBN steel strictly control quality of our carbon steel plate, alloy steel plates and structural steel plates. For A283 Gr C CS steel carbon plate ASTM A572 Grade 50 structural steel plate, Our Q/C Department will inspect dimension before shipment, making sure structural steel plate thickness tolerance and width, length tolerance are matchable to the A283 Gr C CS steel carbon plate standard requirements. The company is a good ASTM A572 grade 50 structural steel plate supplier in the globle market and the head is located in China. Welcome to send us inquiry and questions about structural steel plate.
