description | Provided is a steel pipe for a fuel injection line, having a chemical composition, expressed in weight percent, of C: 0.12-0.27%, Si: 0.05-0.40%, Mn: 0.3-2.0%, Al: 0.005-0.060%, N: 0.0020-0.0080%, Ti: 0.005-0.015%, Nb: 0.015-0.045%, Cr: 0-1.0%, Mo: 0-1.0%, Cu: 0-0.5%, Ni: 0-0.5%, V: 0-0.15%, and B: 0-0.005%, with the remainder being Fe and impurities. The content of Ca, P, S, and O among the impurities is Ca: 0.001% or less, P: 0.02% or less, S: 0.01% or less, and O: 0.0040% or less. The pipe has a metallographic structure comprising a tempered martensite structure or mixed structure of tempered martensite and tempered bainite, and has a prior austenite grain size number of 10.0 or above, and tensile strength TS of 800 MPa or above, as well as a critical internal pressure of at least [0.3*TS*alpha] (where alpha=[(D/d)2-1]/[0.776*(D/d)2], D: steel pipe outside diameter (mm), and d: steel pipe inside diameter (mm)).
