-6 /℃ 이하인 Ni기 합금으로 형성된 제1 부재와, 고크롬강으로 형성된 제2 부재를 용접에 의해 접합함으로써 구성되고, 650℃ 이상의 작동 유체와 접하는 부위를 상기 Ni기 합금으로 형성한 제1 부재로 한다.
An object of the present invention may be bonded by another heat-resistant steel material such as a Ni-based alloy and 12Cr steel for welding, and can maintain the strength at the joint, employed in the 700 ℃ grade steam conditions possible turbine rotor and a method of manufacturing the same to provide. Is provided in the rotating device which is a working fluid is introduced at least 650 ℃, in a plurality of members of a different intensity, depending on the working fluid temperature flowing through the rotor of the joint rotating unit by welding, the average coefficient of linear expansion of up to 700 ℃ from room temperature 12.4 × 10
-6 / ℃ to 14.5 × 10
-6 / ℃, preferably 14.0 × 10
-6 / ℃ or less joined by a second member formed of a first member and a high chrome steel is formed of a Ni-based alloy for welding by configuration and and the contact portion and at least 650 ℃ working fluid to a first member formed with the Ni-based alloy.
