Maintenance

Regular Inspection: Regularly check the surface of the steel to see if there is any abnormal corrosion or damage. If rust spots or other damages are found, corresponding treatment measures should be taken in a timely manner.

Cleaning: Use a soft - bristle brush or a mild cleaning agent to clean the surface of the steel to remove dust, dirt, and other substances to prevent them from adhering to the steel surface and affecting the formation of the rust - resistant layer. Avoid using high - pressure water jets or harsh cleaning agents to prevent damage to the surface rust - resistant layer.

Avoid Contact with Dissimilar Metals: When using A588 GrK steel, avoid direct contact with dissimilar metals to prevent galvanic corrosion. If it is necessary to connect with other metals, appropriate isolation measures should be taken.
