Nta

Kuj muaj peev xwm ntawm qib 347/347H
Cov qib no muaj qhov zoo sib xws ntawm kev tiv thaiv corrosion raws li qib chromium stabilized.Nws muaj zuag qhia tag nrho thiab hauv zos corrosion kuj muaj peev xwm.Feem ntau, nws yog qib SS stabilized uas muaj kev tiv thaiv zoo heev rau intergranular corrosion nyob rau hauv raug kub kub.Nws yog resistive rau chromium carbide ntau ntawm nag lossis daus (sensitization) nyob rau hauv qhov kub ntawm 427 mus rau 816 degree C. Nws yog stabilize tiv thaiv chromium carbide tsim.
Alloy 347 / 347H yog qhov cuam tshuam rau kev ntxhov siab corrosion cracking (SSC) hauv halides ib puag ncig.Qhov no yog vim nws cov ntsiab lus nickel.Nws muaj alloying ntsiab tso cai rau nws siv nyob rau hauv lub pitting thiab crevice corrosion ib puag ncig.Nws nthuav tawm oxidation tsis kam piv rau cov qib pa.Cov khoom siv lub cev xav tau yog muab los ntawm cov txheej txheem kho cua sov.Feem ntau alloy 347 yog tsis-sib nqus nyob rau hauv cov xwm txheej nyob rau hauv lub annealed tej yam kev mob, txawm li cas los xij, me ntsis dhau los ua hlau nplaum thaum raug rau kev ua haujlwm txias.
Tsim cov ntsiab lus
Nws muaj qhov ua tau zoo txias ua haujlwm hardening.Qhov kub ua kom sov ntawm cov hlau yog 2100- 2250 ° F thiab nws raug pom zoo rau kev tsim khoom.Nws yog tam sim ntawd quenched los yog tag nrho annealed uas khaws ntau dua txhua yam khoom.Nws muaj zoo weldability, machinability, formability, thiab fabricability feature.
Kev tshuaj xyuas cov khoom
Thaum lub sij hawm tsim khoom, muaj ntau lub caij nyoog ntawm faulty cov khoom uas yog tsim.Txhawm rau tshem tawm lawv, lawv raug tshuaj xyuas hauv peb qhov chaw sim.Cov kev ntsuam xyuas los ntawm peb yog cov kev ntsuam xyuas kev ruaj ntseg, PMI test, hardness test, Thermal performance test, thiab tshuaj ntsuam xyuas.Lwm qhov kev ntsuam xyuas yog kev sim tshuab, kev ntsuas kev puas tsuaj, kev sim macro, IGC xeem, pitting corrosion test, compression test, to test, thiab ultrasonic test.
