MX CARBONITRIDE PRECIPITATION-STRENGTHENED HEAT-RESISTANT STEEL |
摘要 |
PROBLEM TO BE SOLVED: To provide an MX carbonitride precipitation-strengthened heat-resistant steel which is a heat-resistant steel utilizing a strengthening mechanism by the precipitation of carbonitride and in which the high-temperature creep strength at 600 to 650°C is improved. SOLUTION: The MX carbonitride precipitation-strengthened heat-resistant steel utilizes a strengthening mechanism by the precipitation of MX carbonitride and has the improved high-temperature creep strength at 600 to 650°C, wherein the content of a compound MX carbonitride comprising NbC (TaC) and VN is restricted to below 30% by weight with respect to the entire precipitated MX carbonitride.
