On March 19, 2020 the us international trade commission (ITC) vote on imports from China and India's carbon alloy steel screw (CarbonandAlloySteelThreadedRod) to make a positive final anti-dumping and anti-subsidy industry damage. All five members of the international trade commission voted in favor of the ruling. The us department of commerce will issue anti-dumping and countervailing duty orders on imports of carbon alloy steel screws from China and India, according to the itc's affirmative ruling.

Q345 and Q345B are steel numbers The differences are as follows:
1 Q345 is general and does not indicate the quality level; Q345B is clear and the quality level is B
2 Q345 does not require to inspect the impact performance; Q345B requires that the impact performance at room temperature is qualified (impact at 20 ℃)
3 Q345 does not indicate carbon content of steel; Q345B carbon content is 020%
Q345 refers to carbon structural steel with yield point (σ s) of 345MPa The following letters indicate the quality level, including A, B, C, D and E,QStE500TM automotive steel coil.

The basic phases of structural steel in the annealed state are ferrite and carbide The alloy elements are dissolved in ferrite to form alloy ferrite, which depends on solid solution strengthening to increase strength and hardness, but at the same time reduce plasticity and toughness The addition of alloying elements reduces the carbon content of the eutectoid point, which increases the proportion of pearlite in the structure and reduces the distance of the pearlite layer This also increases the strength of the steel and reduces the plasticity,QStE500TM automotive steel coil.
