<p>A martensitic heat-resistant steel that is excellent in high-temperature creep strength, contains Co, and does not yield an intermetallic compound with an approximate composition of Cr40Mo20Co20W10C2-Fe at a temperature as high as 600 °C. The deposition of the above intermetallic compound is suppressed and an excellent high-temperature creep strength is secured by adding minute amounts of Mg, Ba, Ca, Y, Ce, La, etc., and small amounts of Ti and Zr to a heat-resistant steel containing at least 8 % Cr and also Co, Mo and W.</p> |
