OEM/ODM Supplier Astm A106 Gr. B Hot Rolled Seamless Steel Pipe - Q345 ASTMGr.50 ISOE355CC JISSN400 low alloy high strength structural seamless steel pipe – Huayi Detail:
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.
