Zusammenfassung:	An objective of the present disclosure is to provide a high strength and lightweight fuel pipe for a mobility by increasing a nickel equivalent, configuring an alloy composition having price competitiveness, and designing optimized pipe dimensions to a pipe for carrying hydrogen formed in the alloy composition under applicable pressure.According to the objective, the present disclosure provides an alloy material having a Ni equivalent (Nieq) over 28.5% by controlling the composition of C, Si, Mn, P, S, Ni, Cr, and Mo, a pipe is machined using the alloy material, and a high-strength pipe of about 1/8 hard is provided by applying a strength increasing technology using work hardening and heat treatment.
