摘要

The present invention provides a method of bonding steel members by bonding a plurality of steel members made of a Cr-containing steel material to each other. The method includes a united body forming step S10 in which a united body is formed by making the plurality of steel members butted to each other and by heating the plurality of steel members to a first temperature while pressing the plurality of steel members under a predetermined pressure condition; and a bonding strength enhancing step S30 in which the united body is heated to a second temperature equal to or above an A1 transformation point of the steel material and, subsequently, is gradually cooled to a third temperature equal to or below 600° C. under a condition that lowering of temperature to 600° C. from A1 transformation point takes 10 hours or more in this order. According to the method of bonding steel members of the present invention, even when the united body is manufactured by bonding the plurality of steel members made of a Cr-containing steel material to each other, the united body can acquire a sufficiently high bonding strength.
