Advantages of Q420qDNH bridge weathering steel

Advantages of Q420qDNH bridge weathering steel:
1. Good low-temperature toughness, which can meet the requirements of impact energy of more than 150J under the environment of - 40℃.
2. With high weatherability index, it can resist atmospheric, seawater and other corrosion and prolong its service life.
3. The resistance to lamellar tearing is excellent, meeting the requirements of Z35 grade.
4. Low-carbon design ensures good welding performance. It can be directly welded without preheating during processing, which is convenient for customers' later installation and production.
5. Short lead time can reduce manufacturing costs for customers.
