Kev ntsuas kub siab Mechanics
Lub npe "H" hauv S347H qhia txog nws cov ntsiab lus carbon siab. Thaum cov pa roj carbon tsawg yog ib txwm nyiam los txwv kev xeb thaum lub sijhawm vuam, cov pa roj carbon elevated yog qhov tseem ceeb rau siab -kub txhua yam khoom.
Creep Strength thiab Stress Rupture
Hauv kev tsim hluav taws xob tseem ceeb hauv cov kav dej thiab cov tshuab ua kom zoo, cov hlau nyob hauv qhov kev ntxhov siab ntawm qhov kub siab tau ua kom qis, deformation mus tas li nyob rau lub sijhawm- txheej txheem hu uankag.
S347H xa ntau tshajob zaug lub creep rupture zogntawm tus qauv 304H lossis 316H ntawm qhov kub siab tshaj 700℃(1292℃F).
Kev faib tawm tsis sib xws ntawm NbC precipitates muab cov hlua khi kom muaj zog, tiv thaiv micro-cov qauv slippage uas ua rau nkag tsis tau.
Oxidation thiab Scaling Resistance
Nruam kev caij tsheb kauj vab tuaj yeem ua rau muaj kev tiv thaiv oxides ntawm cov hlau tsis tshua muaj zog kom tawg, ua rau kom nrawm nrawm ntawm cov yeeb nkab phab ntsa. S347H nthuav tawm ruaj khov oxidation thiab scaling tsis kam mus txog kev ua haujlwm tsis tu ncua ntawm750℃(1382℃F), nrog luv luv - lub sij hawm mus ncig ua si ntev mus txog 900℃(1652℃F).
Manufacturing Standards thiab Processing Guidelines
Ntiaj teb no kev lag luam Specifications
S347H cov kav dej yog tsim nyob rau hauv cov qauv thoob ntiaj teb nruj nyob ntawm daim ntawv thov zaum kawg:
ASTM A312 / ASME SA312 Cov Lus Qhia:Qhia meej seamless, ncaj-seam welded, thiab hnyav hnyav- ua haujlwm welded austenitic kav npaj rau siab - kub thiab kev pabcuam corrosive.
ASTM A213 / ASME SA213 Cov Lus Qhia:Npog seamless ferritic thiab austenitic steel boiler, superheater, thiab cua sov- cov raj xa dej.
ASTM A358 / ASME SA358 Cov Lus Qhia:Governs Electric-Fusion-Welded (EFW) kav tsim los rau siab -siab configurations.
Kev kho cua sov raws tu qauv
Ua kom tau txais cov yam ntxwv zoo txhua yam yuav tsum tau ua cov txheej txheem thermal:
Kev daws Annealing:Cov khoom yuav tsum tau rhuab nyob rau hauv qhov ntau ntawm1925 ° F txog 2000 ° F (1050 ° txog 1100 ° F), ua raws li cov dej nrawm nrawm los yog yuam cua txias kom tiv thaiv theem nrab precipitates.
Stabilization Thaum tshav kub kub kho:Feem ntau teev rau qhov hnyav heev - kev pabcuam ib puag ncig, cov txheej txheem no ua kom sov cov yeeb nkab mus txog 1600℃F–1650℃F (870℃-900℃). Qhov no ua rau niobium carbide nag lossis daus ua ntej kev pabcuam, ua kom ntseeg tau tias tom qab qis dua - qhov kub thiab txias tsis tuaj yeem ua rau muaj kev kub ntxhov.
