30Crmnornor steel yog hom siab-} performance performance performance້ນ optimoy້ນ optim້ອງ siv tau zoo, muaj zog, tawv, thiab coj tsis kam. Hauv qab no yog cov ncauj lus kom ntxaws ntawm nws cov yam ntxwv tseem ceeb, kev ua tau zoo, thiab kev siv:

1. Tshuaj Muaj Tshuaj

Qhov "re" hauv nws cov qauv qhia tau hais tias ntxiv rauTsis tshua muaj ntiaj teb ntsiab lus(piv txwv li, cerium, vinethanum), uas ua lub luag haujlwm tseem ceeb hauv kev tsim kho cov qauv graphing thiab txhim kho cov hlau qhov kev ua tau zoo tag nrho. Cov ntsiab lus tseem ceeb suav nrog:

 

Chromium (CR): Txhim kho cov khoom siv nyuaj, xeb tsis kam, thiab hnav tsis kam.

Manganese (MN): txhim kho lub zog, ua tsis tau, thiab tawv.

Molybdenum (mo): nce siab siab - lub zog kub, txo kom muaj kev kub taub hau, thiab ua rau muaj zog.

Tsis tshua muaj lub ntiaj teb (R)

2. Cov Khoom Siv Neeg Kho Tshuab

Tom qab kev kho cua sov kom zoo (feem ntau quenching thiab tempering), 30cmmore cov khoom pov thawj zoo heev kev ua haujlwm zoo heev:

 

Lub zog tensile: Ntau dua los yog sib npaug rau 1,080 MPa

Paib lub zog: Ntau dua los yog sib npaug rau 880 MPa

Elongation: Ntau dua los yog sib npaug rau 10% (qhia tau cov khoom muaj peev xwm zoo heev)

Kev Cuam Tshuam Tougness (AKV, Chav Chav): Ntau dua los yog sib npaug rau 39 J (zoo heev tiv taus rau kev cuam tshuam sai sai

Kev nyuaj: 28-32 HRC tom qab Tempering (tsis muaj zog thiab lub tshuab txua)

 

 

 

 

 

 

3. Tseem Ceeb Zoo

Siab zog thiab kev sib npaug sib npaug: Kev sib xyaw ua ke ntawm lub zog siab tensile lub zog thiab cov kev cuam tshuam zoo ua rau muaj kev cuam tshuam hnyav thiab kev cuam tshuam zoo tsis muaj plhuav, ua rau nws haum rau cov khoom siv nyuaj.

Cov Hardener Tsis Muaj Peev Xwm: Vim yog cov nyhuv synergistic ntawm cr, mn, thiab mo, cov hlau tuaj yeem yog cov khoom siv nyuaj, ua kom cov khoom siv tshuab hluav taws xob hla cov khoom.

Txhim Kho Microstructure kev ruaj khov: Tsis tshua muaj lub ntiaj teb tseem ceeb dua cov qauv sib dhos, txo cov kev phom sij (piv txwv li, cov leeg nqaij), thiab txhim kho cov hlau tiv thaiv thiab nkag.

Cov Khoom Zoo Kuj: Tom qab kev kho mob saum npoo (piv txwv li, carburizing), nws tuaj yeem ua tiav cov npoo tawv siab, txhim kho cov kev coj tsis kam rau qhov chaw xws li cov khoom plig lossis hauv cov duab.
