Title:
CUTTING PROCESSING METHOD OF SEAMLESS STEEL PIPE
Document Type and Number:
Japanese Patent JP2017035745
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a cutting processing method of a seamless steel pipe capable of improving production efficiency, while restraining cutting resistance and agglutination in screw cutting processing time.SOLUTION: A cutting processing method of a seamless steel pipe by the present embodiment comprises a process of preparing a base material and a process of cutting processing. In the process of preparing the base material, the base material having a structure of including Cr:16.0-18.0% in mass% and including a ferrite phase, a martensite phase and a residual austenite phase is prepared. In the process of cutting processing, the base material is cut-processed by using a cutting tool. Assuming the contact area (mm) between the cutting tool and the base material as S, in the case of 0.2≤S≤2.0 mm, a cutting speed is set to 150-350 m/min, and in the case of 2.0
