Qhov sib txawv ntawm 13crmo 4-5 thiab 10cmroid {

1. sib txawv hauv cov tshuaj muaj kuab lom
13clo 4-5:
Chromium (CR) Cov ntsiab lus: 0 {}}}}}}}}}}}}) (molybdenum (mo) Cov ntsiab lus: 0.40% ~ 0.60%.
Cov pa roj carbon (c) Cov ntsiab lus tsawg: 0 {{}} 08% ~ 0,1%, phosphorus (p) tsawg dua lossis sib npaug rau 0.025%.
10Clo 9-10:
Chromium cov ntsiab lus yog siab dua: {{{{}} 00% ~ 2.50, molybdenum cov ntsiab lus: 0.90% ~ 1.10%.
Cov ntsiab lus carbon yog qhov siab dua me ntsis: 0 {}}} 09% ~ 0.16%

{{0 {}} kev ua tiav thiab thov sib piv
Kev Kub Siab Tshaj:
13clo {{4-5}: muaj feem xyuam rau tsawg dua lossis sib npaug zos, nrog nruab nrab kev sib sau ua ke thiab kev laus tom qab siv ntev {}}
10clo {{9-10: qhov ntsuas kub tshaj plaws yog 620 degree, haum rau ultra-siab siab chav tshuab {}}
Lub zog thiab tawv:
13clo {{4-5}: Tensile Lub Zog 450-600MPA, Tawm Zog Rau 290Mpa, Elongation ntau dua los yog sib luag rau 19% .
10clo {{9-10}: Tensile Lub Zog 480-660MpaSxy, tawm suab ntau dua los yog sib npaug rau 18% .
Daim Ntawv Thov Qhia:
13clo {{4-5: feem ntau yog siv rau nruab nrab thiab qis} 88mpa), petrochemical cua sov sib pauv thiab cov hlab kub tsis kub.
10Crmo 9-10}: Tshwj xeeb siv rau cov nruas kub (ntau dua los yog sib npaug ntawm 9.

3. Txheem thiab cov txheej txheem sib txawv
Kev siv cov qauv: ob qho tib si ua raws cov en 10216-2 Tus Qauv Siv Hluav Taws Xob Sa387 graphic {}}} Hais rau sa387 gr.12.
Kev Kho Cua Sov:
13clo {{4-5 feem ntau yog li qub + tempered (n + t);
10clo 9-10 Yuav tsum tau kev kho mob quenching thiab temperinging (Q + t) kom ntseeg tau high-kub}
4. vuam thiab corrosion tsis kam
13clo {{4-5} muaj cov pa roj carbon ntau (cev) ntawm txog 0.45%, thiab xav tau preheated ntawm 200-300℃ua ntej vuam;
10clo 9-10} muaj ntau cov txheej txheem vuam ntau dua vim nws cov ntsiab lus high alloy .
Lub chromium-molybdenum piv ntawm 10clo9-10 Tseem cuam tshuam tau daws qhov muaj peev xwm tiv thaiv hydrogen corrosion (hatha).
Ntsiab lus: 10Crmo 9-10 yog qhov siab dua-}} Qhov kev xav tau ntawm ob qho yog qhov sib txawv ntawm .
