Abstract The development of hot rolled strip for J55 ERW casing produced with Nb micro alloying at Baotou CSP plant is introduced. The strips have good mechanical properties,including cold bending, weld ability and thread machining etc. The Integrated properties of casing are conformed to API 5CT standard and costumer requirements completely. 10000 t strips was produced and used very well.

Key words： CSP Nb microalloyed J55
