BOLT, METHOD OF MANUFACTURING BOLT AND REACTOR INSIDE STRUCTURE OF NUCLEAR REACTOR

摘要

PPROBLEM TO BE SOLVED: To provide a bolt having high strength and high corrosion resistance. PSOLUTION: This manufacturing method of the bolt 11 is characterized by forming a frictional padding layer 3 by cladding a highly hard-highly corrosion resistant material 2 on a surface 4 by frictional agitation, or forming a frictional agitation layer 23 by frictionally agitating an unconsumed highly hard material 22 on a surface of a stainless steel base material, and forming a thread on this frictional padding layer 3 or the frictional agitation layer 23.
