What is the cause of cracks in weather-resistant steel plates?

September 01, 2023

Weather-resistant steel plate has the advantages of atmospheric corrosion resistance and seawater corrosion resistance, and is mainly used in urban landscape, park modeling, urban curtain wall and other places. Hot rolled corrosion resistant special steel, container plate, weather resistant bridge steel, seawater corrosion resistant steel, atmospheric corrosion resistant structural steel, construction machinery steel beam steel, rich resources, reasonable price products, material specifications of a wide variety.

Weather resistant steel plate

The key to the initial hardening trend is the composition, sheet thickness, welding method and refrigeration standard. The greater the hardening trend of steel, the more likely it is to cause cold cracks.

2. The effect of hydrogen and hydrogen is one of the key elements of aging resistance and cold crack resistance of extremely high compressive strength Shatin 16CuCr weathering steel plate, and has the characteristics of delay time. The higher the hydrogen composition of the high toughness weathering steel plate, the stronger the crack sensitivity.

3. Aging resistance to ground stress: The tendency of Shatin 16CuCr weathering steel plate to cause delay time cracks lies not only in its hardening trend and the effect of hydrogen, but also in aging resistance to ground stress. The key ground stresses of weather-resistant Shatin 16CuCr steel plate are: welding stress caused by uneven heating and cooling, structural ground stress caused by changes in metal materials, and structural self-restraint.
