Among plates, Q345B low alloy seamless steel pipe belongs to the low alloy series. Among low alloy materials, this material is the most common. Q345B low alloy seamless steel pipe used to be called: 16Mn seamless steel pipe.
The external implementation standard of Q345B low alloy seamless steel pipe is: GB709, and the internal implementation standard is: GB/T1591-94.
Similar to the naming method of Q345B.
Due to the implementation of standards, this type of steel plate is allowed to be delivered with negative tolerances.
Q345 low alloy seamless steel pipe is a kind of steel pipe material. Q represents the yield of this material, and the following 345 refers to the yield value of this material, which is around 345. And as the thickness of the material increases, its yield value decreases.
Q345A level, no impact; Q345B level, 20 degree normal temperature impact; Q345C level, 0 degree impact; Q345D level, -20 degree impact; Q345E level, -40 degree impact. At different impact temperatures, the impact values are also different.
Q345A, Q345B, Q345C, Q345D, Q345E. This is a distinction between levels, and what it represents is mainly that the temperature of the impact is different。
