Mechanical Properties thiab Kev kho cua sov

ASME SA387 Qib 12 feem ntau yog muab rau hauvnormalized thiab tempered (N + T)mob kom ntseeg tau tias tsis sib xws microstructure thiab ruaj khov mechanical zog.

Cov yam ntxwv mechanical zog:

• Tensile zog:415-585 MPa
• Yield zog (min):205 MPa
• Elongation:Ntau dua lossis sib npaug li 18%
• Kev ntsuam xyuas cuam tshuam: Muaj nyob ntawm qhov kev thov

Qhov kub no- kho mob kom ntseeg tau zoo heevsiab- bearing muaj peev xwm, toughness, thiab fabrication ntseeg tau, tshwj xeeb tshaj yog rau cov phaj tuab.

High -Tsub Kev Ua Haujlwm Zoo

Piv nrog rau cov pa roj carbon siab lub nkoj steels, SA387 Qib 12 Cr-Mo steel muab kev ua tau zoo tshaj plaws hauv qhov chaw kub siab.

Cov txiaj ntsig tseem ceeb muaj xws li:

Zoo heevcreep zogntawm qhov kub thiab txias

Muaj zogoxidation thiab scaling kuj

Txhim khu kev ua tau zoo hauvhydrogen- muaj ib puag ncig

Txo qhov kev pheej hmoo ntawm thermal qaug zog thaum lub sijhawm ua haujlwm cyclic

Cov txiaj ntsig zoo no ua rau SA387 Gr 12 zoo tagnrho rau cov cuab yeej ua haujlwm tas mus li qhov ntev - lub sijhawm ruaj khov yog qhov tseem ceeb.

Sib piv: SA387 Qib 12 vs 13CrMo44

SA387 Qib 12 thiab13 CrMo44feem ntau suav hais tias sib npaug rau ntau daim ntawv thov.

Txawm hais tias cov tshuaj muaj pes tsawg leeg thiab kev ua tau zoo sib xws, kev hloov pauv zaum kawg yuav tsum ua raws litsim code pom zoo thiab qhov yuav tsum tau ua.
