Abstract

Use of a steel alloy as a material for fuel distributors is new. The alloy contains (in wt.%) 0.09-0.13 C, 0.15-0.30 Si, 1.10-1.60 Mn, less than 0.015 P, less than 0.011 S, 1.00-1.60 Cr, 0.30-0.60 Mo, 0.02-0.05 Al, 0.12-0.25 V and a balance of Fe. The steel has a tensile strength Rm of more than 850 N/mm2, an apparent yielding point Rp0.2 of more than 700 N/mm2 and an elongation A5 of more than 15 %.
