Joining method of steel members, and joint strengthening methods and steel products in the assembly consisting of steel members

摘要

A bonded body forming step S120 that the prepare steel member preparation step S110 steel members of two containing Cr, to form a conjugate joined together steel members of two bonding method of steel members of the present invention, the junction After heating to a second temperature in the range of 800 ℃ ~1150 ℃ the body, by a third temperature of 600 ℃ below until annealing the assembly, and bonding strength strengthening step S140 to enhance bonding strength of the conjugate comprises in this order the door, in the steel member preparation step S110, the steel members 2, prepare the sintered steel members of two in assembly forming step S120, by bonding together the sintered steel members of two It is characterized by forming a conjugate. Therefore, according to the joining method of the steel member of the present invention, it is possible to obtain sufficiently high bonding strength even when manufacturing a bonded body by bonding to each other steel members of two containing Cr.
