Maintenance Key Points for Q345E High-Strength Steel Plate

Q345E high-strength steel plate boasts excellent comprehensive mechanical properties and low-temperature impact toughness, widely used in bridges, construction, machinery manufacturing, and other fields. Proper maintenance can extend its service life and maintain stable performance. Below are specific maintenance recommendations:

1. Storage Environment Management

Moisture and Rust Prevention

Store in a dry and ventilated area to avoid direct contact with rainwater or fog on the steel plate surface.

Raise the steel plates with wooden pallets, channel steel, etc., to a height of ≥10 cm to isolate them from the ground and prevent moisture erosion.

For long-term storage, apply rust-proof oil (e.g., petroleum jelly, industrial rust-proof grease) or cover with moisture-proof paper/plastic film, particularly paying attention to edges and cut surfaces.

Avoid Stacking and Extrusion

Ensure the load-bearing capacity of the bottom steel plates when stacking. Use wooden boards or rubber pads between layers to prevent surface scratches or deformation.

Keep the stacking height ≤2 meters and regularly inspect the stability of the stack to avoid collapse risks.

Environmental Temperature Control

Avoid long-term storage in extreme temperatures (e.g., high heat, severe cold) to prevent internal stress from thermal expansion/contraction or cracking of surface coatings.
