Mechanical Properties
Tensile:≥690 MPa;Yield:≥310 MPa;Elong:≥30%
Equivalent Standards
AMS 5662
Equivalent Grades
Maintain the recommended heat-treatment envelope; prolonged time in embrittlement ranges reduces ductility. Use descaling/protective atmosphere to limit scaling.
Applications
沉淀硬化镍基，航空主力。,"Bar
Available Forms
Forging
Uses
Plate"
Heat Treatment
Heat- and creep-resistant steel for elevated-temperature service with stable strength and oxidation resistance. Used in furnace parts, exhaust manifolds, turbine components, boiler tubes and engine valves.
Precautions
Normally used in the solution-annealed or precipitation-hardened condition; stabilise/age per the grade (e.g., 650–800 °C ageing). Avoid long exposure in the sigma/475 °C embrittlement ranges.
