Tensile strength,σb/≥ MPa: 1120
Tensile strength,σb/≥ MPa: 1120
Yield strength, σ0.2/≥ MPa: 725
Elongation, δ ≥(％): 15.0
Reduction of area, ф ≥ (％): 15.0
Hardness | HBW: 310 min.
STRESS RUPTURE REQUIREMENT
Test temperature: 816 Deg.
Stress /MPa: 260
Time to rupture: 100h
Elongtation, (%): 5.0
TYPICAL APPLICATIONS
Starndard specification for high-temperature bolting, with expansion coefficients comparable to austenitic stainless steel with yield strength ranging from 345 to 827 MPa for use in high-temperature service such as fasteners for pressure vessel and valve flanges.
Nuclear reactor, Turbine engine parts - mechanical gears, gear shaft, main axis, blade.
Mechanical parts - bolt and nut, fastener.
Gas turbine blade, Fuel nozzle.
These materials must stand up to high heat, extreme oxidation potential and recycling.
