- •
Novel Cu-bearing high-strength pipeline steels were developed.
- •
The microstructure with uniformly distributed fine Cu-rich precipitates was obtained.
- •
The novel pipeline steel achieved a high strength with excellent resistance to hydrogen-induced cracking.
- •
Cu-rich precipitates contribute to both strengthening and hydrogen traps.
