Effect of humidity and temperature on corrosion of KF32 hull structural steel sheet

The company adheres to the management concept of "people-oriented, talent is concerned", develops business with the spirit of "believing strength, practical style, KF32 hull structural steel sheet professional service and dare to compete", and provides customers with "professional, value-added and effective" service support. For the company's development and take-off, we work together to move forward and create a better KF32 hull structural steel sheet tomorrow!

Q345qC steel plate is the steel plate of bridge structure, the implementation standard is GB / T 714-2015 standard. KF32 hull structural steel sheet, Q345qC-Z25 steel: Q represents the yield strength, 345 represents the small yield strength, the unit is MPa, q is short for the bridge, C quality grade, corresponding to the corresponding impact temperature and impact work value, Z is the Z-direction performance that is the performance of the steel plate thickness direction, Z25 is the Z-direction Performance level requirements.

High wear resistance: fully automatic CNC stacking equipment, independent of manual KF32 hull structural steel sheet welding technology, produces fully qualified high-quality products. Special automatic welding technology enables the chromium content of wear-resistant layer to be controlled at more than 28%, and the KF32 hull structural steel sheet hardness is between 58-62, which fully ensures that our wear-resistant layer has continuous good and balanced wear resistance. The wear test in metallurgy, cement and other industries shows that the wear resistance of the wear-resistant layer of the surfacing composite KF32 hull structural steel sheet wear-resistant steel plate is more than 30 times that of the 16Mn plate with the same thickness.

Try to use KF32 hull structural steel sheet high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the KF32 hull structural steel sheet temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.
