STRESS RUPTURE REQUIREMENT
Test temperature: 760 Deg.
Stress /MPa: 325
Time to rupture: 23h
Elongtation, (%): 3.5
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.
