Verification of Allowable Stresses In ASME Section III

The database for the creep-rupture of 9Cr-1Mo-V (Grade 91) steel was collected and reviewed to determine if it met the needs for recommending time-dependent strength values,S {sub t},for coverage in ASME Section III Subsection NH (ASME III-NH) to 650 C (1200 F) and 600,000 hours.T91 / P91 SteelThe T91/ P91 steel is primarily used for superheater and reheater in power plant boiler construction,headers,main steam pipeline,as well as the heating furnace piping in petrochemical industry.Compared to other austenitic alloy steels,it has better thermal conductivity and thermal expansivity.T91 - Steel GradesTool Die Steels Inc.Stainless Steel,Special Steel,Compressor Blading,Turbine Blading,Superalloy Supplier.T91 Round Bar T91 Flat Bar T91 Hollow Bar T91 Tube / Pipe T91 Sheet / Plate T91 Strip / Coil T91 Wire T91 Forging T91 Tube / Pipe TEL:+86-13880247006
