In order to improve the economic efficiency of oil and gas transportion, pipeline steels are developing to ultra-high strength level. The development and performance of ultra-high strength pipeline steels are reviewed and discussed on the view point of chemical composition design, strengthening mechanism, toughness improvement, and production technology. Regarding the combination of high strength and good toughness in conjunction with excellant weldability, the technology difficulties on the development of ultra-high strength steels are discussed. The trend on the production technology and special welding process are outlined.
