weight of S460ML plate sheet

The company has allocated special environmental protection facilities for all S460ML plate sheet pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, S460ML plate sheet steel mill scale, environmental protection dust has reached 100%.

Magnetic particle flaw detection is only suitable for detecting surface defects, which means that by laying magnetic powder on the surface of the equipment and using its aggregate shape on the surface defects of the magnetic material equipment to determine the position, size and shape of the defect. This S460ML plate sheet method has a relatively low cost and is easy for steel production enterprises to adopt in batches. However, for special steel profiles with deeper thickness, whether this method is used to detect hidden defects is yet to be verified.

Our company has a comfortable office environment, covers a large area, can accommodate hundreds of people working at the same time. All kinds of green plants are placed in the company, with a healthy office environment. Our company also has gym, table tennis, leisure bar, kitchen, refrigerator, microwave oven and other equipment. Humanized construction provides comfortable office environment for employees.

What is the difference between Q345B steel and Q345A steel? S460ML plate sheet, 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.
