Top Grade Hot Selling ASTM A106 A53 Hot Rolled Low Carbon Steel Pipe Carbon Steel Seamless Tube

Short Description:

Q345 seamless pipe belongs to low alloy series – low alloy high strength structural steel (GB / t1591-1994). Q345A, B, C, D and E are the representative grades of this kind of steel. Compared with carbon structural steel, Q345A has the advantages of high strength, good comprehensive performance, long service life, wide application range and relatively economic. It is widely used in bridges, ships, boilers, vehicles and important building structures.

Product Description

Q345 is a kind of low-alloy steel with good comprehensive mechanical properties, low-temperature properties, good plasticity and weldability. It is used for medium and low pressure vessels, oil tanks, vehicles, cranes, mining machinery, power stations, bridges and other structures, mechanical parts, building structures and general metal structures under dynamic load. Q345A, Q345B, Q345C, Q345D, Q345E. The main reason is that the impact temperature is different. Q345A level, is not to do impact; Q345B, 20 ℃ impact at room temperature; Q345C, 0 degree impact; Q345D is – 20 degree impact; Q345E is – 40 degree impact. At different impact temperature, the impact value is different. In the plate, it belongs to low alloy series. In the low alloy material, this material is the most common. Q345 used to be called 16Mn. Due to the implementation of the standard, this kind of steel plate is allowed to be delivered with negative tolerance.
