Factory price of 4.2mm coil nm400 mechanical properties per ton

The market demand affects the NM400 mechanical properties, stainless steel price: if the downstream industries such as infrastructure, real estate and hardware products have strong production demand and large procurement volume, it will naturally affect the price of stainless steel. And these large macro data will be disclosed by related statistical departments, therefore, stainless steel purchasers need to understand the macro economic data. Secondly, the international market trade environment and policies among countries will also have a certain impact on the import and export of stainless steel.

What is the difference between Q345B steel and Q345A steel? NM400 mechanical properties, Q345B steel and Q345A steel have slight difference in chemical composition: Q345A steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.045, S ≤ 0.045, V 0.02 ~ 0.15; Q345B steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.040, S ≤ 0.040, V 0.02 ~ 0.15. The difference between Q345B steel and Q345A steel is mainly in A and B behind the steel grade, Q345A steel grade is not subject to impact; Q345B steel grade needs 20 ℃ room temperature impact test.
