| Abstract: | IIIX15 6earinK steel tubes produced with the Process of rapid coolies to 200-400 ℃ after hot-rolling-sizing (reducing) while reheatin8 to critical temperature}then cooling in air will have much shorter globurizing time.The Properties of the tubes after globurizingare hidher than that specified by OCT800-78 standard. |
