16MnDR steel has good corrosion resistance at low temperature, but it is still necessary to take some anti-corrosion measures to extend its service life. The following are common anti-corrosion measures:

1. Surface treatment: Before use, the surface of 16MnDR steel is purified, such as rust removal, sandblasting or pickling, etc., to remove oxides, dirt and impurities to ensure that the surface is clean.

2. Anti-corrosion coating: After surface treatment, apply appropriate anti-corrosion coating to isolate the direct contact between the steel and the environmental medium. Commonly used anti-corrosion coatings include coatings, epoxy resins, polymer coatings, etc. Select the appropriate coating type and thickness to respond to the specific working environment and corrosive media.

3. Cathodic protection: Use cathodic protection technologies, such as current anode protection (ICCP) or sacrificial anode protection (SACP), to make 16MnDR steel a cathode, thereby reducing its corrosion rate in corroded batteries. This method is often used for buried pipelines and underwater structures.

4. Regular maintenance: Regular inspection and maintenance of 16MnDR steel structure, including patching and updating of coating, to ensure the integrity of its anti-corrosion layer. Timely treatment and repair of possible damage or corrosion problems to prevent further corrosion development.

5. Immersion coating: For some special cases of 16MnDR steel structures, such as the inner wall of storage tanks, you can consider using immersion coating technology to immerse the entire steel in a coating solution with anti-corrosion properties.

The appropriate anti-corrosion measures need to be selected according to the specific working environment and application requirements, and the operation and maintenance are carried out in strict accordance with the relevant norms and standards. This can maximize the corrosion resistance of 16MnDR steel and extend its service life.
